Watches with automatic winding
1. Winding your watch
You do not need to wind this watch as it winds itself
when you move. Alternatively, however, you canwind your watch by turning the crown clockwise withyour thumb and index finger. Unlike with handwound watches you will not feel any resistance fromautomatic models when they are fully wound. Note:
With neomatik calibers (DUW 3001 and DUW 6101)
the rotor will stop when the watch is fully wound.
This is to protect the mainspring. If you don’t wear
your watch, it has a power reserve of up to 43 hourswhen fully wound.

2. Setting the date	DUW 5101 and Zeta calibers
You can set the date by turning the hour hand backand forth between 8 p.m. and 1 a.m. If your watch
has spent your vacation in a drawer, for example, andyou want to correct it from September 1 to September 16, you don’t need to wind it on 24 hours fifteentimes. First, set your watch to 1 a.m. so the datechanges. Then turn the hands counterclockwise toabout 8:30 p.m. Now turn them forward, back to
1 a.m.: the date will change again. If you then needto set the time, please pay attention to whether it
is 10 a.m. or 10 p.m., as the date will only change at
midnight instead of midday if this is correct.	NOMOS DUW 6101
automatic movement
For watches with a neomatik caliber, the date can be
set even faster. In the second crown position—
simply pull the crown out a little—you can quickly set
the date backwards and forwards; just a half-turnof the crown will change the date. Additionally,the DUW 6101 has extra-short lockout times: simply
avoid resetting the date between 11:15 p.m. and12:45 a.m. If you attempt to do so anyway: no problem.
DUW 6101 has been constructed so that this does
not damage the mechanism. If the date gets stuck
between two positions, simply pull out the crown as
far as it will go and set the time forward to 1 a.m.—or back to 11 p.m.: the date indicator will then jumpback to its original position. The time can be set on
watches with this caliber in the outermost, that’s to
say the third, crown position.

3. Setting the time and time zones

General maintenanceComplications made uncomplicated: setting a NOMOS
watch with a world time complication is reallysimple—and is done in just three small steps.

1. CaseTangomat GMT
1.	Set the reference time: Push the button until yourtime zone appears in the window on the left.
2.	Synchronize the time: The recessed button (corrector button) can be pressed using the setting pin—
until the hour hand displays the time of the hourdisc on the right.
3.	Set the current time: As usual, turn the crown toset your local time (paying attention to the difference between 10 a.m. and 10 p.m.).

Zürich world time
1.	Set the reference time: Push the button until yourtime zone appears at the top of the city dial (i.e.
at 12 o’clock).
2.	Synchronize the time: The recessed button can bepressed using the setting pin—until the hour handdisplays the time of the hour disc on the right.
3. S
 et the current time: As usual, pull out the crown
and turn it to set your local time (paying attention
to the difference between 10 a.m. and 10 p.m.).

The cases of most of our watches are made fromnickel-free stainless steel and sapphire crystal glass.
Only diamond is harder. The sapphire crystal glass
is very slightly raised in order to protect the steel.
The cases of gold NOMOS watches are made of solid
gold (18 carat), so they are particularly valuable.
As gold—rose gold, white gold and yellow gold—issofter than stainless steel, small scratches cannot
be avoided—but they also depict life, beautifully demonstrating the history of the watch.

2. Water resistanceIf your NOMOS watch bears the 30 atm or 20 atm
suffix, this means according to the corresponding
DIN standard: you can take it diving with you without
any concern. The 10 atm designation indicates thatyour watch is suitable for swimming and snorkeling,and 5 atm means it can be worn when showering.
All other NOMOS models are water resistant to 3 atm—
and prefer to stay dry. They are splashproof,
meaning you can wash your hands with them on, but
it is better to take them off when swimming. It isalso recommended to have the water resistance ofa mechanical watch checked once a year by yourretailer—it doesn’t take long.
Caution: The Ahoi, Tangente Sport and Club Sportneomatik 42 date models have a screwed-downcrown. Please screw it down tightly after each use as
this is the only way to keep your watch waterproof.
To do so, press the crown gently against the case inits default position and turn it clockwise until you
feel noticeable resistance. Also important: Never pullout the crown under water.

3. Magnetic fields
Magnetic fields can damage all mechanical watches.
It is better to avoid them. If you notice any fixed
rate deviation, this could be due to the magnetizationof your watch. A watchmaker can quickly fix this.

4. Service
As a rule, a mechanical watch should be serviced
every five years, when it will be cleaned and freshly
oiled. We recommend that you bring it to yourretailer for servicing at these intervals.
