Item 1.  BUSINESS

      (a)  General  Development  of  Business.  Dean  Witter

Spectrum  Technical L.P. (the "Partnership") is  a  Delaware

limited  partnership  formed to engage  in  the  speculative

trading  of  futures and forward contracts  and  options  on

futures  contracts, and on physical commodities,  and  other

commodity interests, including foreign currencies, financial

instruments,   precious   and  industrial   metals,   energy

products,    and   agriculturals   (collectively    "futures

interests").

           An  aggregate  of  10,000,000  Units  of  limited

partnership  interest ("Units") in the Partnership  and  its

affiliated partnerships, Dean Witter Spectrum Balanced  L.P.

and  Dean  Witter  Spectrum Strategic L.P., were  registered

pursuant  to a Registration Statement on Form S-1 (File  No.

33-80146) which became effective on September 15, 1994, with

an   arbitrary   allocation  of  4,000,000  Units   to   the

Partnership.    The  offering  of  units  was   underwritten

initially  at $10.00 per unit on a "best efforts"  basis  by

Dean   Witter  Reynolds  Inc.  ("DWR").   The  Partnership's

General    Partner   is   Demeter   Management   Corporation

("Demeter").  DWR and Demeter are wholly-owned  subsidiaries

of  Morgan  Stanley, Dean Witter, Discover & Co.  ("MSDWD").

The  Partnership commenced operations on November  2,  1994.

An   aggregate  of  14,000,000  additional  Units   in   the

Partnership were

                              

                              

<PAGE>

registered pursuant to the Registration Statement on Form S-

1 (File Nos. 333-00494 and 333-3222), which became effective

on January 31, 1996 and April 30, 1996, respectively.  Units

of  limited  partnership  interest are  offered  at  monthly

closings at a price equal to 100% of the Net Asset Value per

Unit  as  of  the close of business on the last day  of  the

month.

     Through July 31, 1997, the sole commodity broker of the

Partnership's transactions was DWR.  On July 31,  1997,  DWR

closed  the  sale of its institutional futures business  and

foreign  currency trading operations to Carr  Futures,  Inc.

("Carr"),   a   subsidiary  of  Credit  Agricole   Indosuez.

Following  the  sale,  Carr became  the  clearing  commodity

broker  for  the  Partnership's futures and futures  options

trades  and  the  counterparty on the Partnership's  foreign

currency  trades.  DWR serves as the non-clearing  commodity

broker for the Partnerships with Carr providing all clearing

services for the Partnerships' transactions.

      The  Partnership's  Net Asset Value  per  Unit  as  of

December  31, 1997 was $14.63, representing an  increase  of

7.49 percent from the Net Asset Value per Unit of $13.61  on

December 31, 1996.  For a more detailed description  of  the

Partnership's business see subparagraph (c).

     (b) Financial Information about Industry Segments.  The

Partnership's  business  comprises  only  one  segment   for

financial   reporting  purposes,  speculative   trading   of

commodity futures contracts and other



<PAGE>

commodity interests.  The relevant financial information  is

presented in Items 6 and 8.

     (c) Narrative Description of Business.  The Partnership

is  in  the  business  of speculative trading  in  commodity

futures contracts and other commodity interests, pursuant to

trading  instructions provided by Campbell & Company,  Inc.,

Chesapeake Capital Corporation and John W. Henry  &  Company

Inc.,  ("JWH")  its  independent trading  advisors.   For  a

detailed  description  of  the  different  facets   of   the

Partnership's   business,  see   those   portions   of   the

Partnership's   Prospectus,  dated  April  25,   1997   (the

Item 2.  PROPERTIES

        The executive and administrative offices are located

<PAGE>

Item 3.  LEGAL PROCEEDINGS

        On  September 6, 10, and 20, 1996, and on March  13,

1997,  similar  purported class actions were  filed  in  the

Superior  Court of the State of California,  County  of  Los

Angeles, on behalf of all purchasers of interests in limited

partnership  commodity pools sold by DWR.  Named  defendants

include   DWR,  Demeter,  Dean  Witter  Futures  &  Currency

Management Inc. ("DWFCM"), MSDWD (all such parties  referred

to  hereafter as the "Dean Witter Parties"), certain limited

partnership commodity pools of which Demeter is the  general

partner,  and  certain trading advisors (including  JWH) to

those  pools.  On June 16, 1997, the plaintiffs in the above

actions  filed  a consolidated amended complaint,  alleging,

among  other  things, that the defendants  committed  fraud,

deceit,  negligent misrepresentation, various violations  of

the  California Corporations Code, intentional and negligent

breach  of  fiduciary duty, fraudulent and  unfair  business

practices, unjust enrichment, and conversion in the sale and

operation  of  the  various limited  partnerships  commodity

pools.   Similar purported class actions were also filed  on

September 18 and 20, 1996, in the Supreme Court of the State

of  New  York, New York County, and on November 14, 1996  in

the  Superior  Court  of the State of Delaware,  New  Castle

County,  against the Dean Witter Parties and certain trading

advisors  (including  JWH) on behalf of  all  purchasers  of

interests in various limited partnership

<PAGE>

commodity  pools  sold  by DWR. A consolidated  and  amended

complaint in the action pending in the Supreme Court of  the

State  of  New  York was filed on August 13, 1997,  alleging

that  the  defendants committed fraud, breach  of  fiduciary

duty,  and  negligent  misrepresentation  in  the  sale  and

operation  of  the  various  limited  partnership  commodity

pools.  On December 16, 1997, upon motion of the plaintiffs,

the  action  pending in the Superior Court of the  State  of

Delaware  was voluntarily dismissed without prejudice.   The

complaints  seek  unspecified amounts  of  compensatory  and

punitive  damages  and other relief.  It  is  possible  that

additional  similar actions may be filed and  that,  in  the

course  of  these actions, other parties could be  added  as

defendants.  The Dean Witter Parties believe that they  have

strong  defenses  to, and they will vigorously  contest  the

actions.  Although the ultimate outcome of legal proceedings

cannot  be  predicted with certainty, it is the  opinion  of

management of the Dean Witter Parties that the resolution of

the  actions will not have a material adverse effect on  the

financial condition or the results of operations of  any  of

the Dean Witter Parties.

                              

Item 4.  SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

Item  5.  MARKET FOR THE REGISTRANT'S PARTNERSHIP UNITS  AND
RELATED
         SECURITY HOLDER MATTERS

       There is no established public trading market for the

Units  of  Limited Partnership Interest in the  Partnership.

The  number  of holders of Units at December  31,  1997  was

approximately 17,558.  No distributions have  been  made  by

the  Partnership  since it commenced trading  operations  on

November  2,  1994.  Demeter has sole discretion  to  decide

what  distributions, if any, shall be made to  investors  in

the  Partnership.  No determination has yet been made as  to

future distributions.

       Dean   Witter  Spectrum  Strategic  L.P.   ("Spectrum

Strategic"); Dean Witter Spectrum Technical L.P.  ("Spectrum

Technical");   and  Dean  Witter  Spectrum   Balanced   L.P.

("Spectrum   Balanced"  and,  collectively   with   Spectrum

Strategic   and   Spectrum  Technical,  the  "Partnerships")

collectively   registered  10,000,000   Units   of   Limited

Partnership  Interest ("Units") pursuant to  a  Registration

Statement  on Form S-1, which became effective on  September

15, 1994 (the "Registration Statement") (SEC File Number 33-

80146).   While  such  Units were not  allocated  among  the

Partnerships at that time, they were subsequently  allocated

for  convenience  purposes as follows:   Spectrum  Strategic

4,000,000,   Spectrum  Technical  4,000,000   and   Spectrum

Balanced   2,000,000.    The  Partnerships   registered   an

additional  20,000,000 Units pursuant to a new  Registration

Statement on Form S-1, which become effective on January 31,

1996 (SEC

<PAGE>

File Number 333-00494); such units were allocated among  the

Partnerships  as  follows:   Spectrum  Strategic  6,000,000,

Spectrum   Technical   9,000,000   and   Spectrum   Balanced

5,000,000.    The  Partnerships  registered  an   additional

8,500,000  Units pursuant to another Registration  Statement

on  Form S-1, which become effective on April 30, 1996  (SEC

File  Number 333-3222); such Units were allocated among  the

Partnerships  as  follows:   Spectrum  Strategic  2,500,000,

Spectrum   Technical   5,000,000   and   Spectrum   Balanced

1,000,000.  The managing underwriter for the Partnerships is

DWR.

      The "Initial Offering" by the Partnerships, when Units

were sold for $10 each, commenced on September 15, 1994  and

closed  on  November 2, 1994; a "Continuing Offering"  began

thereafter,  during which Units are being  sold  at  monthly

closings  as of the last day of each month at a price  equal

to  100% of the Net Asset Value of a Unit as of the date  of

such monthly closing.

      Through  December 31, 1997, 13,917,669.201 Units  were

sold,  leaving 4,082,330.799 Units unsold as of  January  1,

1998.    The   aggregate  offering  amount  registered   was

$201,920,000, based upon the offering prices of $10 per Unit

for  the  4,000,000 Units registered on September 15,  1994;

$11.73  per  Unit  for  the 9,000,000  Units  registered  on

January 31, 1996; and





<PAGE>

$11.27 per Unit for the 5,000,000 Units registered on  April

30, 1996.

The  aggregate price of the Units sold through December  31,

1997 is $169,694,891.

      Since  DWR  has paid all expenses of the  Initial  and

Continuing  Offerings, and no other expenses are  chargeable

against proceeds, 100% of the proceeds of the offering  have

been  applied to the working capital of the Partnership  for

use  in accordance with the "Use of Proceeds" section of the

Prospectus included as part of each Registration Statement.

Item  7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
CONDITION AND            RESULTS OF OPERATIONS

      Liquidity.  The Partnership's assets are on deposit in

separate  commodity interest trading accounts with  DWR  and

Carr, the commodity brokers, and are used by the Partnership

as  margin to engage in commodity futures, forward contracts

and  other  commodity interest trading.  DWR and  Carr  hold

such   assets  in  either  designated  depositories  or   in

securities   approved  by  the  Commodity  Futures   Trading

Commission  ("CFTC") for investment of customer funds.   The

Partnership's  assets held by DWR and Carr may  be  used  as

margin  solely  for  the Partnership's trading.   Since  the

Partnership's sole purpose is to trade in commodity  futures

contracts and other commodity interests, it is expected that

the  Partnership will continue to own such liquid assets for

margin purposes.

      The  Partnership's  investment  in  commodity  futures

contracts,  forward contracts and other commodity  interests

may be illiquid.  If the price for a futures contract for  a

particular commodity has increased or decreased by an amount

equal  to the "daily limit", positions in the commodity  can

neither  be taken nor liquidated unless traders are  willing

to  effect trades at or within the limit.  Commodity futures

prices  have occasionally moved the daily limit for  several

consecutive  days  with little or no trading.   Such  market

conditions  could  prevent  the  Partnership  from  promptly

liquidating its commodity futures positions.



<PAGE>

      There is no limitation on daily price moves in trading

forward  contracts on foreign currencies.  The  markets  for

some  world  currencies  have low  trading  volume  and  are

illiquid, which may prevent the Partnership from trading  in

potentially  profitable markets or prevent  the  Partnership

from  promptly  liquidating unfavorable  positions  in  such

markets and subjecting it to substantial losses.  Either  of

these  market  conditions could result  in  restrictions  on

redemptions.

      Market  Risk.  The Partnership trades futures, options

and  forward  contracts  in interest rates,  stock  indices,

commodities   and  currencies.   In  entering   into   these

contracts  there  exists a risk to the  Partnership  (market

risk) that such contracts may be significantly influenced by

market   conditions,  such  as  interest  rate   volatility,

resulting  in  such contracts being less valuable.   If  the

markets  should  move  against all of the  futures  interest

positions held by the Partnership at the same time,  and  if

the  Trading Advisors were unable to offset futures  interest

positions of the Partnership, the Partnership could lose all

of  its assets and the Limited Partners would realize a 100%

loss.   The  Partnership has established  Trading  Policies,

which  include  standards for liquidity and  leverage  which

help  control  market risk.  Both the Trading  Advisors  and

Demeter  monitor  the  Partnership's trading  activities  to

ensure  compliance with the Trading Policies.   Demeter  may

(under terms of

                              

<PAGE>

the Management Agreements) override the trading instructions

of a  Trading Advisor to the extent necessary to comply with

the Partnership's Trading Policies.

      Credit  Risk. In addition to market risk, in  entering

into  futures,  options and forward  contracts  there  is  a

credit risk to the Partnership that the counterparty on  the

contract  will  not be able to meet its obligations  to  the

Partnership.   The ultimate counterparty of the  Partnership

for  futures contracts traded in the United States and  most

foreign  exchanges on which the Partnership  trades  is  the

clearinghouse associated with such exchange.  In general,  a

clearinghouse  is backed by the membership of  the  exchange

and  will act in the event of non-performance by one of  its

members  or  one of its member's customers,  and,  as  such,

should  significantly reduce this credit risk.  For example,

a  clearinghouse may cover a default by (i) drawing  upon  a

defaulting  member's  mandatory  contributions  and/or  non-

defaulting   members'  contributions  to   a   clearinghouse

guarantee fund, established lines or letters of credit  with

banks, and/or the clearinghouse's surplus capital and  other

available assets of the exchange and clearinghouse, or  (ii)

assessing  its  members.   In cases  where  the  Partnership

trades on a foreign exchange where the clearinghouse is  not

funded or guaranteed by the membership or where the exchange

is  a  "principals'  market" in  which  performance  is  the

responsibility of the exchange member and not the

<PAGE>

exchange or a clearinghouse, or when the Partnership  enters

into  off-exchange contracts with a counterparty,  the  sole

recourse  of the Partnership will be the clearinghouse,  the

exchange  member or the off-exchange contract  counterparty,

as the case may be.

      There  can  be  no  assurance  that  a  clearinghouse,

exchange  or other exchange member will meet its obligations

to   the   Partnership,  and  the  Partnership  is   not

indemnified  against a default by such parties from  Demeter

or  MSDWD or DWR.  Further, the law is unclear as to whether

a  commodity  broker  has  any  obligation  to  protect  its

customers   from   loss  in  the  event  of   an   exchange,

clearinghouse  or  other exchange member default  on  trades

effected for the broker's customers; any such obligation  on

the  part  of the broker appears even less clear  where  the

default occurs in a non-US jurisdiction.

       Demeter   deals  with  the  credit   risks   of   all

partnerships  for  which it serves as  General  Partner  in

several ways.  First, it monitors each partnership's  credit

exposure to each exchange on a daily basis, calculating  not

only  the  amount  of margin required for it  but  also  the

amount  of  its unrealized gains at each exchange,  if  any.

The  commodity brokers inform each partnership, as with  all

their customers, of its net margin requirements for all  its

existing  open positions, but do not break that  net  figure

down,  exchange by exchange. Demeter, however, has installed

a system which permits it to monitor each Partnership's

<PAGE>

potential  margin liability, exchange by exchange.   Demeter

is   then  able  to  monitor  the  individual  partnership's

potential net credit exposure to each exchange by adding the

unrealized  trading gains on that exchange, if any,  to  the

partnership's margin liability thereon.

       Second,  as  discussed  earlier,  each  partnership's

trading policies limit the amount of partnership Net  Assets

that can be committed at any given time to futures contracts

and  require,  in  addition,  a certain  minimum  amount  of

diversification in the partnership's trading,  usually  over

several different products.  One of the aims of such trading

policies  has  been  to reduce the credit  exposure  of  any

partnership  to any single exchange and, historically,  such

partnership exposure has typically amounted to only a  small

percentage of its total Net Assets.  On those relatively few

occasions where a partnership's credit exposure has  climbed

above that level, Demeter has dealt with the situations on a

case by case basis, carefully weighing whether the increased

level  of  credit  exposure remained  appropriate.   Demeter

expects  to  continue  to deal with  such  situations  in  a

similar manner in the future.

     Third, Demeter has secured, with respect to Carr acting

as  the clearing broker for the partnerships, a guarantee by

Credit  Agricole Indosuez, Carr's parent, of the payment  of

the  "net  liquidating value" of the transactions  (futures,

options and forward contracts) in each

                              

<PAGE>

partnership's  account.   As of December  31,  1997,  Credit

Agricole Indosuez' total capital was over $3.25 billion  and

it is currently rated AA2 by Moody's.

       With   respect  to  forward  contract  trading,   the

partnerships  trade  with  only those  counterparties  which

Demeter,   together  with  DWR,  have   determined   to   be

creditworthy.    At   the  date  of  this filing,   the

partnerships  deal only with Carr as their  counterparty  on

forward   contracts.   The  guarantee  by   Carr's   parent,

discussed above, covers these forward contracts.

      See  "Financial Instruments" under Notes to  Financial

Statements  in  the  Partnership's  1997  Annual  Report  to

Partners, incorporated by reference in this Form 10-K.

      Capital Resources.  The Partnership does not have, nor

does  it  expect to have, any capital assets.   Redemptions,

exchanges  and sales of additional Units of Limited Partnership

Interest in the future  will affect  the  amount  of funds available

for  investments  in subsequent periods.  As redemptions are at the

discretion of Limited Partners, it is not possible to estimate the

 amount and therefore, the impact of future redemptions.

ANNUAL REPORT
1997
 
Dear Limited Partner:
 
This marks the fourth annual report for Dean Witter Spectrum Series. The Net
Asset Value per Unit for each of the three Dean Witter Spectrum Funds as of
December 31, 1997 were as follows:
 
<TABLE>
<CAPTION>
      FUNDS         N.A.V. % CHANGE FOR YEAR
      -----         ------ -----------------
<S>                 <C>    <C>
Spectrum Balanced   $13.75       18.2%
Spectrum Strategic  $10.71        0.4%
Spectrum Technical  $14.63        7.5%
</TABLE>
 
DEAN WITTER SPECTRUM BALANCED L.P., a Fund that replicates a balanced portfolio
of stocks, bonds and managed futures utilizing the futures, options and forward
markets, achieved a profitable year. In January, the Fund recorded gains in the
currency markets from short positions in most European currencies as the value
of the U.S. dollar strengthened relative to these currencies. Additional gains
were recorded in the stock index portion of the balanced portfolio as long S&P
500 Index futures positions profited from an increase in domestic stock prices.
During February, gains were recorded in the currency markets from a continued
strengthening in the value of the U.S. dollar relative to most European
currencies, as well as the Singapore dollar. Additional gains were recorded
from short energy futures positions as oil and gas prices declined, and from
long positions in corn futures as prices in this market moved higher. In March,
losses were recorded from long S&P 500 Index futures positions as U.S. stock
prices moved lower late in the month. In currencies, a portion of previous
months' profits was given back as the previous upward trend in the value of the
U.S. dollar relative to most European currencies reversed lower.
<PAGE>
 
The Fund experienced losses during April from short U.S. interest rate futures
positions in the managed futures component as U.S. bond prices rallied late in
the month, after showing signs of trending lower previously. These losses were
partially offset by gains recorded from long positions in both the stock index
and bond components of the balanced portfolio as prices in the domestic capital
markets increased. During May, profits were recorded from long positions in
Australian bond futures as prices in this market moved higher. Additional gains
were recorded from long positions in U.S. stock index and bond futures as
prices in these markets continued their upward trend. This bullish trend in
U.S. equity and bond prices continued into June, thus resulting in additional
profits for the Fund's long positions. Gains were also recorded from long
Australian bond futures positions, as prices moved higher, and from long
Japanese yen positions as the value of the yen increased versus the U.S.
dollar.
 
The third quarter began with additional gains being recorded in the stock index
and bond futures components of the balanced portfolio as U.S. stock and bond
prices continued to move higher. Gains were also recorded in the managed
futures portion from long positions in U.S. and Australian interest rate
futures, as well as from a strengthening in the value of the U.S. dollar.
During August, a price reversal lower in U.S. stock index and bond futures, as
well as in international bond futures, resulted in a portion of previous
months' profits being given back. In September, gains were recorded from long
positions in the stock and bond portions of the portfolio as U.S. stock index
and bond futures prices regained their previous upward momentum. Additional
gains were recorded in the managed futures component from long positions in
global interest rate futures.
 
Losses were recorded during October from long S&P 500 Index futures positions
as U.S. equity prices declined sharply on October 27. These losses were
mitigated as stock prices rebounded on October 28. Smaller losses were
<PAGE>
 
experienced from long positions in Australian and European interest rate
futures as prices in these markets reversed lower during early October. During
November, the Fund recorded a small loss primarily from long U.S. Treasury note
futures positions as prices moved lower. A majority of these losses were offset
by gains recorded from long S&P 500 Index futures positions as U.S. stock
prices rallied late in the month. In the managed futures portion, small losses
were experienced from long energy futures positions as oil and gas prices
declined on easing tensions in Iraq. During December, gains were recorded from
short positions in most Pacific Rim currencies, particularly the New Zealand
and Singapore dollars, as the value of these currencies declined over concerns
of economic instability in Asia. Additional gains were recorded from short
positions in crude oil and natural gas futures.
 
DEAN WITTER SPECTRUM STRATEGIC L.P., a Fund managed by three trading advisors
who employ fundamental trading methodologies in a diverse portfolio of futures,
recorded a small net gain in net asset value per unit for the year. During
January, the Fund posted losses primarily from choppy price movement in global
interest rate futures. Smaller losses were experienced from short positions in
S&P 500 Index futures as U.S. stock prices moved higher. During February,
significant profits were recorded from short energy futures positions as oil
and gas prices moved lower as demand declined due to unseasonably warm weather
in key market areas. Additional gains were recorded from long positions in
silver and copper futures. In March, the Fund profited from short U.S. interest
rate futures positions as domestic bond prices dropped off due in large part to
an increase in the Fed Funds rate late in the month. Additional gains were
recorded from short S&P 500 Index futures positions as U.S. equity prices also
moved lower during late March.
 
In April, losses were recorded due primarily to choppy price movement in
European interest rate futures. Additionally, a portion of previous months'
profits was given back as
<PAGE>
 
short positions in U.S. interest rate futures experienced losses due to a rally
in U.S. bond prices late in the month after showing signs of weakening
previously. During May, the Fund recorded small profits as long positions in
copper and zinc futures profited from an increase in base metals prices. In
currency trading, gains from transactions involving the Japanese yen more than
offset losses from transactions involving the British pound. In June, losses
were recorded from long positions in soybean and soybean products as prices
moved lower. Smaller losses were experienced from short-term volatile price
movement in Japanese government bond futures. These losses were partially
offset by gains from long cocoa futures positions.
 
In July, gains were recorded from short positions in most major foreign
currencies as the value of the U.S. dollar strengthened relative to these
currencies. Additional gains were recorded from long positions in global
interest rate and stock index futures as prices in these markets moved higher.
During August, losses were experienced from long positions in these same
markets as prices reversed lower. Smaller losses were recorded from long
positions in aluminum and copper futures as prices declined. The Fund recorded
losses during September from short positions in S&P 500 Index futures as the
U.S. stock market regained its previous bullish momentum. Smaller losses were
recorded from long positions in soft commodities as prices moved lower.
 
During October, losses were recorded from long positions in base and precious
metals futures as prices declined. Smaller losses were recorded from short-term
volatility in the value of the Japanese yen and Swiss franc relative to the
U.S. dollar. These losses were partially offset by gains from long positions in
corn and soybean meal futures as prices increased. In November, the Fund
experienced losses from short positions in U.S., Hong Kong and German stock
index futures as most global equity prices rebounded higher after moving
sharply lower in late October and early
<PAGE>
 
November. Smaller losses were experienced from long cocoa futures positions as
prices moved lower. These losses were partially offset by gains recorded from
short Japanese yen positions as the value of the yen weakened versus the U.S.
dollar due to the economic turmoil in Asia. Profits were also recorded during
December from short Japanese yen positions as the value of the yen continued to
decline versus the U.S. dollar amid concerns over the instability of the
Japanese economy. Additional gains were recorded from long silver futures
positions.
 
DEAN WITTER SPECTRUM TECHNICAL L.P., a Fund managed by three trading advisors
who employ long-term technical trend-following trading systems across a diverse
portfolio of futures, recorded net gains for the year. In January, gains were
recorded from short positions in the German mark, Swiss franc and Japanese yen
as the value of the U.S. dollar strengthened relative to these currencies.
Additional gains were recorded from short gold futures positions as gold prices
declined to their lowest levels since 1993. A continued strengthening in the
value of the U.S. dollar versus most major European currencies during February
resulted in additional currency gains for the Fund's short German mark and
Swiss franc positions. Long positions in coffee futures profited from an upward
price trend as concerns about declining supplies grew stronger. During March, a
portion of previous months' profits were given back as the previous downward
trend in the value of the German mark and Swiss franc reversed higher relative
to the U.S. dollar. Smaller losses were recorded from short positions in the
energy markets as oil and gas prices reversed higher after moving lower during
February.
 
In April, losses were recorded from short positions in U.S. interest rate
futures established during late March as U.S. bond prices rallied higher late
in the month after moving lower previously. During May, losses were recorded in
currencies from short positions in the Japanese yen as the previous decline in
the value of the yen reversed higher
<PAGE>
 
relative to the U.S. dollar in late May. Subsequently, additional losses were
recorded in late May from newly established long yen positions as its value
reversed lower late in the month. In June, gains were recorded as long
positions in global interest rate and stock index futures profited from an
upward price trend. Additional gains were recorded in currency trading from
long Japanese yen positions as the value of the yen moved higher.
 
In July, gains were recorded from long positions in global financial futures as
prices in these markets continued to trend higher. Additional gains were
recorded from short positions in the German mark and Swiss franc as the
previous strengthening in the value of the U.S. dollar relative to these
currencies reemerged. Smaller gains were recorded from short gold futures
positions as prices declined early in the month. During August, losses were
recorded from long positions in international interest rate futures as prices
in these markets reversed lower after previously trending higher. These losses
were partially offset by gains from short Nikkei Index futures positions as
Japanese equity prices declined. September was profitable for the Fund as
international bond futures prices regained their previous upward momentum, thus
resulting in gains for the Fund's long positions. Additional gains were
recorded from long positions in European and U.S. stock index futures, as well
as from short positions in Japanese stock index futures. Gains were also
recorded from long natural gas futures positions as prices increased
significantly.
 
Small profits were recorded during October from long British pound positions as
the value of the pound increased relative to the U.S. dollar. Gains were also
recorded from short positions in the Australian and Canadian dollars, as well
as from long Japanese and U.S. bond futures positions. A majority of these
gains were offset by losses experienced from short-term price volatility in
global stock index futures. During November, gains were recorded from short
Japanese yen positions as
<PAGE>
 
the value of the yen trended lower versus other major currencies due to
economic turmoil in Asia. Additional gains were recorded from long British
pound positions as the value of the pound moved higher relative to the U.S.
dollar. Gains were also recorded from short gold futures positions as gold
prices broke below $300 an ounce for the first time in over 12 years. December
was also profitable as silver prices rallied on reports of declining supplies,
thus resulting in gains for long positions. Additional gains in metals were
recorded from short gold futures positions. Profits were also recorded from
long positions in European and U.S. interest rate futures as prices increased
due to a "flight-to-quality" by investors as a result of the Asian economic
crisis.
 
Overall, Spectrum Balanced had a successful year due primarily to a
strengthening in the value of the U.S. dollar during the first quarter, as well
as during December. Additional gains were recorded from long positions in S&P
500 Index futures, as U.S. equity prices continued to trend higher throughout a
majority of the year, and in Australian bond futures, as prices trended higher
during the second and third quarters. Spectrum Balanced's fixed income
component was also profitable as U.S. Treasury note and Treasury bond futures
prices finished the year higher despite trendless price movement throughout the
first half of the year. 1997 was also a profitable year for Spectrum Technical
as long global interest rate futures positions resulted in gains during the
second half of the year. Additional profits recorded in currencies, primarily
from a strengthening in the value of the U.S. dollar relative during January
and February, and again during the final quarter, also contributed to the
overall gains for the year. These gains were partially offset by losses from
trendless price movement in most tangible commodities, with the exception of a
profitable downward trend in gold prices. Spectrum Strategic posted a small net
gain in net asset value per unit during the year as profits were recorded by
the Fund's discretionary managers in the first quarter,
<PAGE>
 
primarily from commodities trading, and again in the year's final months, from
a strengthening U.S. dollar. A majority of these gains were offset by losses
experienced during the second quarter as the volatility in global stock index
and bond futures that began in March did not develop in line with the
discretionary managers' points of view. In much of the second half of the year,
small losses were recorded from significant short-term price volatility.
 
Since inception in November 1994, Spectrum Balanced has increased by 37.5% (a
compound annualized return of 10.3%), Spectrum Strategic has increased by 7.1%
(a compound annualized return of 2.1%) and Spectrum Technical has increased by
46.3% (a compound annualized return of 12.4%).

DEAN WITTER SPECTRUM SERIES
NOTES TO FINANCIAL STATEMENTS
 
1. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
ORGANIZATION--Dean Witter Spectrum Balanced L.P. ("Spectrum Balanced"), Dean
Witter Spectrum Strategic L.P. ("Spectrum Strategic") and Dean Witter Spectrum
Technical L.P. ("Spectrum Technical") (individually, a "Partnership," or
collectively, the "Partnerships") are limited partnerships organized to engage
in the speculative trading of futures and forward contracts, options on futures
contracts and on physical commodities, and other commodities interests,
including foreign currencies, financial instruments, precious and industrial
metals, energy products, and agriculturals. The general partner for each
Partnership is Demeter Management Corporation ("Demeter"). Demeter is a wholly-
owned subsidiary of Morgan Stanley, Dean Witter, Discover & Co. ("MSDWD").
 
On May 31, 1997, Morgan Stanley Group Inc. was merged with and into Dean
Witter, Discover & Co. ("DWD"). At that time, DWD changed its corporate name to
Morgan Stanley, Dean Witter, Discover & Co.
 
Through July 31, 1997, the sole commodity broker for the Partnership's
transactions was Dean Witter Reynolds Inc. ("DWR"), also a subsidiary of MSDWD.
On July 31, 1997, DWR closed the sale of its institutional futures business and
foreign currency trading operations to Carr Futures Inc. ("Carr"), a subsidiary
of Credit Agricole Indosuez. Following the sale, Carr became the clearing
commodity broker for the Partnerships' futures and futures options trades and
the counterparty on the Partnerships' foreign currency trades. DWR serves as
the non-clearing commodity broker for the Partnerships with Carr providing all
clearing services for Partnerships' transactions.
 
Demeter is required to maintain a 1% minimum interest in the equity of each
Partnership and income (losses) are shared by the General and Limited Partners
based upon their proportional ownership interests.
 
BASIS OF ACCOUNTING--The preparation of financial statements in conformity with
generally accepted accounting principles requires management to make estimates
and assumptions that affect the reported amounts in the financial statements.
 
REVENUE RECOGNITION--Commodity futures contracts and forward contracts on
foreign currencies are open commitments until settlement date. They are valued
at market and the resulting unrealized gains and losses are reflected in
income. Monthly, DWR pays each Partnership interest income based upon 80% of
its
<PAGE>
 
DEAN WITTER SPECTRUM SERIES
NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
average daily Net Assets for the month in the case of Spectrum Strategic and
Spectrum Technical and 100% in the case of Spectrum Balanced. The interest rate
is equal to a prevailing rate on U.S. Treasury Bills. For purposes of such
interest payments, Net Assets do not include monies due the Partnership on
forward contracts and other commodity interests, but not actually received.
 
NET INCOME (LOSS) PER UNIT--Net income (loss) per Unit is computed using the
weighted average number of units outstanding during the period.
 
EQUITY IN COMMODITY FUTURES TRADING ACCOUNTS--The Partnerships' assets "Equity
in Commodity futures trading accounts" consist of cash on deposit with DWR and
Carr to be used as margin for trading and the net asset or liability related to
unrealized gains or losses on open contracts and the net option premiums paid
and/or received. The asset or liability related to the unrealized gains or
losses on forward contracts is presented as a net amount in each period due to
master netting agreements.
 
BROKERAGE AND RELATED TRANSACTION FEES AND COSTS-- Prior to September 1, 1996,
brokerage fees for Spectrum Balanced were accrued at a monthly rate of 1/2 of
1% of the Net Assets (a 6% annual rate) as of the first day of each month.
Effective September 1, 1996, brokerage fees were reduced to a monthly rate of
11/24 of 1% of the Net Assets (a 5.5% annual rate) as of the first day of the
month. Effective August 1, 1997, brokerage fees were further reduced to 49/120
of 1% of the Net Assets (a 4.9% annual rate) as of the first day of the month.
 
Prior to September 1, 1996, brokerage fees for Spectrum Strategic and Spectrum
Technical were accrued at a monthly rate of 35/48 of 1% of the Net Assets (an
8.75% annual rate) as of the first day of each month. Effective September 1,
1996, brokerage fees were reduced to a monthly rate of 33/48 of 1% of the Net
Assets (an 8.25% annual rate) as of the first day of the month. Effective
August 1, 1997, brokerage fees were further reduced to 51/80 of 1% of the Net
Assets (a 7.65% annual rate) as of the first day of the month.
 
Such fees will cover all brokerage commissions, transaction fees and costs and
ordinary administrative and continuing offering expenses.
 
OPERATING EXPENSES--The Partnerships incur monthly management fees and may
incur incentive fees. All common administrative and continuing offering
expenses including legal, auditing, accounting, filing fees and other related
expenses, are borne by DWR through the brokerage fees paid by each Partnership.

DEAN WITTER SPECTRUM SERIES
NOTES TO FINANCIAL STATEMENTS--(CONTINUED)
 
 
INCOME TAXES--No provision for income taxes has been made in the accompanying
financial statements, as partners are individually responsible for reporting
income or loss based upon their respective share of each Partnership's revenues
and expenses for income tax purposes.
 
DISTRIBUTIONS--Distributions, other than on redemption of Units, are made on a
pro-rata basis at the sole discretion of Demeter. No distributions have been
made to date.
 
CONTINUING OFFERING--Units of each Partnership are offered at a price equal to
100% of the Net Asset Value per Unit as of the close of business on the last
day of the month. No selling commissions or charges related to the continuing
offering of Units will be paid by the Limited Partners or the Partnership. DWR
will pay all such costs.
 
REDEMPTIONS--Limited Partners may redeem some or all of their Units at 100% of
the Net Asset Value per Unit as of the end of the last day of any month that is
at least six months after the closing at which a person first becomes a limited
partner, upon five business days advance notice by redemption form to Demeter.
Thereafter, Units may be redeemed as of the end of any month upon five business
days advance notice by redemption form to Demeter. However, any Units redeemed
at or prior to the end of the twelfth, eighteenth, or twenty-fourth full months
following the closing at which such person first becomes a limited partner, may
be assessed a redemption charge equal to 3%, 2% or 1%, respectively, of the Net
Asset Value per Unit on the date of such redemption.
 
EXCHANGES--On the last day of the first month which occurs more than six months
after a person first becomes a Limited Partner in any of the Partnerships, and
the end of each month thereafter, Limited Partners may exchange their
investment among the Partnerships (subject to certain restrictions outlined in
the Limited Partnership Agreement) without paying additional charges.
 
DISSOLUTION OF THE PARTNERSHIP--Each Partnership will terminate on December 31,
2035 regardless of its financial condition at such time, or at an earlier date
if certain conditions occur as defined in each Partnership's Limited
Partnership Agreement.
 
2. RELATED PARTY TRANSACTIONS
 
Each Partnership pays brokerage commissions to DWR as described in Note 1. Each
Partnership's cash is on deposit with DWR and Carr in commodity trading
accounts to meet margin requirements as needed. DWR pays interest on these
funds as described in Note 1.

3. TRADING ADVISORS
 
Demeter, on behalf of each Partnership, retains certain commodity trading
advisors to make all trading decisions for the Partnerships. The trading
advisors for each Partnership are as follows:
 
Dean Witter Spectrum Balanced L.P.
 RXR, Inc.
 
Dean Witter Spectrum Strategic L.P.
 Blenheim Investments, Inc.
 A. Gary Shilling & Co., Inc.
 Willowbridge Associates Inc.
 
Dean Witter Spectrum Technical L.P.
 Campbell & Company, Inc.
 Chesapeake Capital Corporation
 John W. Henry & Company, Inc. ("JWH")
 
Compensation to the trading advisors by the Partnerships consists of a
management fee and an incentive fee as follows:
 
MANAGEMENT FEE--The management fee is accrued at the rate of 5/48 of 1% of the
Net Assets on the first day of each month (a 1.25% annual rate) to Spectrum
Balanced.
 
The management fee is accrued at the rate of 1/3 of 1% per month of the Net
Assets allocated to each trading advisor on the first day of each month (a 4%
annual rate) to Spectrum Strategic and Spectrum Technical.
 
INCENTIVE FEE--Each Partnership will pay a monthly incentive fee equal to 15%
of the "Trading Profits", as defined in the Limited Partnership Agreement,
experienced with respect to each trading advisor's allocated Net Assets as of
the end of each calendar month. When trading losses are incurred, no incentive
fee will be paid in subsequent months until all such losses are recovered.
 
4. FINANCIAL INSTRUMENTS
 
The Partnerships trade futures and forward contracts in interest rates, stock
indices, commodities, currencies, petroleum and precious metals. Futures and
forwards represent contracts for delayed delivery of an instrument at a
specified date and price. Risk arises from changes in the value of these
contracts and the potential inability of counterparties to perform under the
terms of the contracts. There are numerous factors which may significantly
influence the market value of these contracts, including interest rate
volatility. At December 31, 1997 and 1996, open contracts were:

A portion of the amounts indicated as off-balance-sheet risk in forward
currency contracts is due to offsetting forward commitments to purchase and to
sell the same currency on the same date in the future. These commitments are
economically offsetting, but are not offset in the forward market until the
settlement date.
 
The unrealized gains on open contracts are reported as a component of "Equity
in Commodity futures trading accounts" on the Statements of Financial Condition
and totaled at December 31, 1997 and 1996, respectively, $681,559 and $216,593
for Spectrum Balanced, $2,527,613 and $140,355 for Spectrum Strategic, and

The contract amounts in the above table represent the Partnerships' extent of
involvement in the particular class of financial instrument, but not the credit
risk associated with counterparty nonperformance. The credit risk associated
with these instruments is limited to the amounts reflected in the Partnerships'
Statements of Financial Condition.
 
Exchange-traded contracts and off-exchange-traded forward currency contracts
held by the Partnerships at December 1997 and 1996 mature as follows:

The Partnerships also have credit risk because either DWR or Carr acts as the
futures commission merchant or the counterparty, with respect to most of the
Partnerships' assets. Exchange-traded futures and options contracts are marked
to market on a daily basis, with variations in value settled on a daily basis.
DWR and Carr, as futures commission merchants for each Partnership's exchange-
traded futures and options contracts, are required pursuant to regulations of
the Commodity Futures Trading Commission to segregate from their own assets,
and for the sole benefit of their commodity customers, all funds held by them
with respect to exchange-traded futures and futures styled options contracts,
including an amount equal to the net unrealized gain on all open futures and
futures styled options contracts, which funds totaled at December 31, 1997 and
1996 respectively, $25,612,869 and $19,420,011 for Spectrum Balanced,
$59,631,616 and $46,138,105 for Spectrum Strategic and $180,827,678 and
$109,262,851 for Spectrum Technical. With respect to the Partnership's off-
exchange-traded forward currency contracts, there are no daily settlements of
variations in value nor is there any requirement that an amount equal to the
net

unrealized gain on open forward contracts be segregated. With respect to those
off-exchange-traded forward currency contracts, the Partnerships are at risk to
the ability of Carr, the sole counterparty on all of such contracts, to
perform. Carr's parent, Credit Agricole Indosuez, has guaranteed Carr's
obligation to each Partnership.
 
For the years ended December 31, 1997 and 1996 the average fair value of
financial instruments held for trading purposes was as follows:

5. LEGAL MATTERS
 
On September 6, 10, and 20, 1996, and on March 13, 1997, similar purported
class actions were filed in the Superior Court of the State of California,
County of Los Angeles, on behalf of all purchasers of interests in limited
partnership commodity pools sold by DWR. Named defendants include DWR, Demeter,
Dean Witter Futures & Currency Management Inc., MSDWD (all such parties
referred to hereafter as the "Dean Witter Parties"), certain limited
partnership commodity pools of which Demeter is the general partner, and
certain trading advisors (including JWH) to those pools. On June 16, 1997, the
plaintiffs in the above actions filed a consolidated amended complaint,
alleging, among other things, that the defendants committed fraud, deceit,
negligent misrepresentation, various violations of the California Corporations
Code, intentional and negligent breach of fiduciary duty, fraudulent and unfair
business practices, unjust enrichment, and conversion in the sale and operation
of the various limited partnerships commodity pools. Similar purported class
actions were also filed on September 18 and 20, 1996, in the Supreme Court of
the State of New York, New York County, and on November 14, 1996 in the
Superior Court of the State of Delaware, New Castle County, against the Dean
Witter Parties and certain trading advisors (including JWH) on behalf of all
purchasers of interests in
<PAGE>
 
DEAN WITTER SPECTRUM SERIES
NOTES TO FINANCIAL STATEMENTS--(CONCLUDED)
 
various limited partnership commodity pools sold by DWR. A consolidated and
amended complaint in the action pending in the Supreme Court of the State of
New York was filed on August 13, 1997, alleging that the defendants committed
fraud, breach of fiduciary duty, and negligent misrepresentation in the sale
and operation of the various limited partnership commodity pools. On December
16, 1997, upon motion of the plaintiffs, the action pending in the Superior
Court of the State of Delaware was voluntarily dismissed without prejudice. The
complaints seek unspecified amounts of compensatory and punitive damages and
other relief. It is possible that additional similar actions may be filed and
that, in the course of these actions, other parties could be added as
defendants. The Dean Witter Parties believe that they have strong defenses to,
and they will vigorously contest, the actions. Although the ultimate outcome of
legal proceedings cannot be predicted with certainty, it is the opinion of
management of the Dean Witter Parties that the resolution of the actions will
not have a material adverse effect on the financial condition or the results of
operations of any of the Dean Witter Parties.
 
6. SUBSEQUENT EVENTS
 
On March 11, 1998, the Partnerships filed a registration statement (the
"Offering") with the Securities and Exchange Commission to update and make
certain changes to the Partnership's registration effective with the first
Monthly Closing of the Offering. These changes include a reduction of brokerage
fees to 4.60% annually for Spectrum Balanced and 7.25% annually for Spectrum
Strategic and Spectrum Technical. At this time the trading program utilized by
Spectrum Balanced will be modified and Spectrum Balanced will be renamed Dean
Witter Spectrum Global Balanced L.P. Additionally, a fourth partnership, Dean
Witter Spectrum Select L.P. ("Spectrum Select") will be made available for
investment and exchanges. Prior to being added to the Spectrum series, Spectrum
Select was a stand alone commodity pool known as Dean Witter Select Futures
Fund L.P.
