(a communication to me from abroad by Alcide Droz et fils of St Imiers,
Switzerland, Watch and Clock Makers.)
This Invention has for its object the construction of a watch hermetically sealed

and setting are effected by means of an arrangement in the pendant outside the
watch and communicating with the interior by means of a "crown" or button
inside the ring or handle.

such flange is made higher and squarer than is usual in watches and there is no
opening to the back of the case. The said rim may also if preferred be screwed on
to the said square part. The pendant is screwed internally so as to receive the

This Invention has for its object the construction of a Watch hermetically sealed
or closed so as to exclude damp and foreign matters and in which the winding and
setting are effected by means of an arrangement in the pendant outside the Watch
and communicating with the interior by means of a "Crown or button inside the
ring or handle-The rim which carries the Glass cemented to it is made to fit on a
flange and such flange is made higher and squarer than is usual in Watches and
there is no opening to the back of the Case-The said rim may also if preferred be
screwed on to the said square part.
The Pendant is screwed internally so as to receive the stem of the "Crown" or
button having on it a left handed screw. When the "Crown" or button is
screwed down it rests externally on a shoulder of the Pendant and internally on
the upper end of the said pendant thereby forming a double closing.
In order to wind the Watch the said "Crown" or button is turned about once
round to the right so as to loosen it then by moving it from left to right and
back again the Watch can be wound as usual It is to be observed that the
hindrance to the winding has been prevented so as to allow of continuous winding
the completion of which can be known by hearing the sound produced by the
mainspring passing from one notch to another in the interior of the barrel-
During this operation the winding spindle will merely have become raised without
causing any derangement and a single turn to the left will return the parts to their
original position-In order to set the watch it is necessary to liberate the stem of
the said "Crown" or button from the screwed part of the pendant. For this
purpose two or three turns to the right are required, then the " crown or button
must be drawn into a raised position which will cause the arm of a rocking lever
to be moved and carry with it this lever to which it is screwed and will thereby
drive a second rocking lever and drop into a notch therein-This second rocking
lever carrying a stud working in a groove of a sliding pinion will move the latter
into gear with the wheel connected with the minute hand and by turning the
or button the Watch can be set as required.

In order to restore the parts to their former position it is sufficient to move the
"crown
or button and screw it again at the bottom
"
Having thus stated the nature of the said Invention I will proceed to describe
more particularly in what manner the same is to be performed by the aid of the
accompanying drawings in which are represented the parts of a Watch above
referred to
DESCRIPTION OF THE DRAWINGS
In the first place the Case for the Glass is made at a time when such Case is no
longer required to be heated in the course of manufacture thereby avoiding all
risk of putting it out of form-The flange A figure 2 is made higher and squarer
than usual the edge of the lunette has a corresponding form-By slightly greasing
the parts in contact an air-tight fastening is secured-The rim B may when
desired have a screw thread formed upon it, the lunette will then be screwed upon
the said square part of the flange and the same result will be obtained
"
Secondly-The Pendant C (figures 1. 2.) is screwed internally at D in order to
receive the stem E of the "crown or button F which has on it a left handed
screw thread When the button F is screwed down it rests on the shoulder G

page_text: formed externally on the pendant and internally on the upper end H of the said
pendant (6gure 1) thereby giving it a double closing
Thirdly The pendant is formed as shown at I. I. figure 1 in order to receive
the ring.
Fourthly, the Glass is cemented in the Case by means of an insoluble and
infusible composition-The operations of winding and setting are effected in the
following manner-In order to wind up the Watch the button E is turned about a
turn to the right so as to loosen it, then by alternate movement from left to right
and vice versa the Watch will be wound in the ordinary manner-It is to be
observed that the stoppage of the winding has been prevented so as to allow of
continuous winding the completion of which can be known by hearing the sound
produced by the mainspring passing from one notch to another in the interior of
the barrel-During this operation the winding spindle J will have merely become
raised without causing any derangement, one turn to the left will then return the
parts to their original position
"
crown or
,,
In order to set the Watch it is necessary to liberate the stem of the "
button E (figure 2) from the screwed part of the Pendant. For this purpose it is
necessary to make three or four turns to the right then to draw the "
button into the position shewn by dotted lines in figure 1 and in the raised
position in figure 2
crown or
In this Movement the Arm L of the rocking lever M (figures 1 and 2) will be
moved and draw with it this rocking lever to which it is screwed-This will
cause the second rocking lever N to be moved so far as to drop into a notch in
the arm O-The rocking lever N carrying a stud P inserted in the Groove R of
the sliding pinion S will move the latter into gear with the wheel T connected
crown or button the Watch can be
with the minute hand and by turning the "
set as required
"
Having thus described the natnre of the said Invention and in what manner the
same is to be performed (communicated to me from abroad as aforesaid) I hereby
declare that what I claim as of the said invention is
The impermeably closed Watch represented in figures 1 and 2 and described
having in it the following characteristics
First An air tight closing obtained by a flange A higher and much less pointed
than usual, which makes a contact with the rim B which has a corresponding
form, the rim B being capable also of being screwed and in that case the lunette
screwed upon the square part of the flange A.
Secondly-The pendant C screwed internally in order to receive the stem of the
"Crown or button having on it a left handed screw and the combination of the
parts G and H the whole being adapted to effect a double closing.
Thirdly The arrangement of a pendant with an opening as described in order
to receive the ring.
And lastly The method of cementing the Glass in the rim and also the method
of effecting the operations of winding and setting substantially in the manner
represented and described
In witness whereof I the said William Heather Spence have hereunto set my
hand and seal the twenty second day of November in the year of Our Lord Oue
thousand eight hundred and eighty three
