Usage and care

1. Winding the watch

This watch does not need to be wound, as it winds itself as you move. Alternatively, you can wind it by turning the crown clockwise between finger and thumb. In contrast to hand-wound watches, automatic watches do not have a point of resistance once they are fully wound—but there’s nothing to worry about; with the neomatik calibers (DUW 3001 and DUW 6101) the rotor reduces its rate of movement once the watch is fully wound. If you don’t wear your watch, it will have a power reserve of at least 43 hours after being fully wound—or one hour less for models with a date function (switching the date requires a little extra energy).

2. Setting the date

a) The calibers DUW 5101 and Zeta

You can set the date by winding the hour hand between eight and one o’clock. For example, if you need to change your watch from the 1st to the 16th September—perhaps after it spent the holidays tucked away safely in a drawer—then you don’t have to wind the hands 30 times around the dial. Start by simply setting the watch to one o’clock the next day, which will change the date. Then wind the hands counterclockwise to around eight thirty in the evening. Now you can wind clockwise to one o’clock, which will change the date again. When you are setting the time afterwards, please check whether you are setting it to ten o’clock in the evening or the morning—as if you get it wrong, the date will change at midday instead of midnight. 

b) The NOMOS neomatik caliber DUW 6101

Watches with this neomatik caliber can be set even more quickly. In the second crown position—which can be found by pulling out the crown just a little—the date can be set forward and backwards with ease; just a half-turn of the crown will move the date once. Furthermore, DUW 6101 has a very small time frame for the date change: simply avoid resetting the date between 11:15 pm and 0:45 am. If you do so accidently, however, don’t worry; DUW 6101 is constructed so that this will not damage the mechanism. Should the date come to a halt while switching between two dates, simply pull the crown out as far as it will go and set the time to shortly after one o'clock in the morning—or back to 11 o'clock at night. Then the date display will return to its original position.
To set the time, just pull the crown a little further out—into the third position.

3. Setting the time and time zone

A perfectly simple complication: Setting a NOMOS watch with a world-time function is very easy—and accomplished in just three steps.

a. Tangomat GMT

• Set the home time zone: Press the pusher above the crown until the city code representing the time zone you want to select as home appears in the window at 9 o'clock. This could be where you live, or a time zone you often work in.
• Synchronize the dials: Use the setting pin provided with the watch to press the corrector point recessed into the case at 8 o'clock repeatedly—until the hour hand on the main dial indicates the same hour as the one marked with the red arrow in the time window at 3 o'clock. This display is now synchronized with the time zone selected as the home time and remains constant, even if you set a new time zone using the world time pusher.
• Set the current time in the home time zone: Pull the crown to the first position and set the time on the main dial as usual. Pay attention to whether it is day or night in your reference zone and continue turning the hands until the 24-hour display in the window at 3 o'clock also shows the correct time. You can then use the pusher to move to other time zones without losing track of whether it is day or night at home.

b. Zürich Worldtimer

• Set the home time zone: Find the city on the city disk that represents the time zone you want to select as home. This could be where you live, or a time zone you often work in. Press the pusher above the crown until this city name is at 12 o'clock.
• Synchronize the dials: Use the setting pin supplied with the watch to press the corrector point, which is recessed into the case at 8 o'clock, repeatedly—until the hour hand on the main dial indicates the same hour as the time disc at 3 o'clock. This display is now synchronized with the time zone selected as the home time, and remains constant even if you set a new time zone using the world time pusher.
• Set the current time in the home time zone: Pull the crown to the first position and set the time on the main dial as usual. Pay attention to whether it is day or night in your home time zone and continue turning the hands until the 24-hour display at 3 o'clock also shows the correct time. You can then use the pusher to move to other time zones without losing track of whether it is day or night at home.

c. Club Sport neomatik Worldtimer

• Set the reference / home time zone: Find the code on the city disk that represents the time zone you want to select as home. This could be where you live, or a time zone you often work in. Press the pusher above the crown until this code is at 12 o'clock.
• Synchronize the dials: Use the setting pin supplied with the watch to press the corrector point, which is recessed into the case at 8 o'clock, repeatedly—until the hour hand on the main dial indicates the same hour as the 24-hour display on the sub-dial. The main dial is now synchronized with the time zone selected to represent home, and remains constant even if you set a new time zone using the world time pusher.
• Set the current time in the reference / home time zone: Unscrew the screw-down crown, pull the crown to the first position, and set the time on the main dial as usual. Pay attention to whether it is day or night in your reference zone and continue turning the hands until the 24-hour display on the sub-dial also shows the correct time. You can then use the pusher to move to other time zones without losing track of whether it is day or night at home.

Daylight Savings Time

If DST is in effect in your reference / home time zone but not in the time zone you want to travel to, you must repeat the synchronization (via the corrector point, see 2). To ensure the correct indication of the home time zone, make sure that the time disc at 3 o'clock shows one hour earlier than the main display. And reverse this when you return to a time zone with DST.

World-time cities and codes

The city codes on the world-time watches from NOMOS Glashütte represent the following time zones (according to Coordinated Universal Time) without taking daylight saving time into account:

LON (London): UTC 0
BER (Berlin): UTC +1
ATH (Athens): UTC +2
MOW (Moscow): UTC +3
DXB (Dubai): UTC +4
KHI (Karachi): UTC +5
DHC (Dhaka): UTC +6
BKK (Bangkok): UTC +7
HKG (Hong Kong): UTC +8
TYO (Tokyo): UTC +9
SYD (Sydney): UTC +10
NOU (Noumea): UTC +11
AKL (Auckland): UTC +12
PPG (Pago Pago): UTC -11
HNL (Honolulu): UTC -10
ANC (Anchorage): UTC -9
LAX (Los Angeles): UTC -8
DEN (Denver): UTC -7
MEX (Mexico City): UTC -6
NYC (New York City): UTC -5
SCL (Santiago de Chile): UTC -4
RIO (Rio de Janeiro): UTC -3
FEN (Fernando de Noronha): UTC -2
PDL (Ponta Delgada): UTC -1

1. Case

The casing of most of our watches is made from nickel-free stainless steel and sapphire crystal glass. The only thing harder than this glass is a diamond. In order to protect the steel, it is very slightly raised.

The cases of the golden NOMOS watches are made of 18 carat gold—as beautiful as they are precious. Since gold—both rose and white gold—is softer than steel, for example, you cannot prevent minor scratches—but it also records its life, the most beautiful way to tell your story.

2. Water-resistance

If your NOMOS watch is water resistant to 20 or 30 atm, you can go diving with it in accordance with the applicable DIN standard. A water resistance of 10 atm means that a watch is suitable for swimming or snorkeling. All other NOMOS models are water resistant up to 3 or 5 atm and prefer to stay dry. They are splash-proof, which means you can wash your hands with them, but it is better to take them off when swimming. It is also advisable to have the water resistance of a mechanical watch checked once a year by a retailer—it's a very quick process.

Please note: Ahoi, Tangente Sport and Club Sport neomatik 42 date, and Club Sport neomatik Worldtimer have screw-down crowns. Please screw it back in fully after each use to ensure that your watch remains water resistant. To do this, press the crown lightly against the case in the home position and turn it clockwise until you feel a clear resistance. Also important: Never pull out the crown under water. The pusher and the corrector point of Club Sport neomatik Worldtimer should also not be operated under water.

3. Magnetic fields

Magnetic fields can harm all mechanical watches, so it’s best to avoid them. If you notice any fixed rate deviation, your watch could have been magnetized. A watchmaker can fix this quickly.

4. Service

A mechanical watch should undergo a complete servicing around once every five years. This involves cleaning and replacing the watch oil lubricating it. We recommend you to take your watch to your retailer for this servicing.
