On the watch
When does it say “Made in Germany” on a NOMOS watch, and when does it say only “Germany?”
The words “Made in Germany” appeared on our models from mid-2003 on. With the move to our self-built movements, we changed the inscription on the dial to the shorter “Germany” at the beginning of April 2005. This abbreviated version later reverted to “Made in Germany” again, simply because it sounds a bit nicer. There’s no difference as far as content is concerned.
How are NOMOS watches adjusted?
The Triovis fine adjustment regulator (something that few manufacturers even offer at all) ensures the greatest possible accuracy. Before leaving NOMOS, all watches are thoroughly put through their places - the NOMOS controllers spend several days testing them in six different positions to ensure each watch is working properly.
Allergies: What kind of materials does NOMOS Glashütte use, and is the stainless steel case nickel-free?
The so-called “nickel directive” came into force in June 2000. It stipulates that objects that come into direct and prolonged contact with the skin may only release 0.5 micrograms of nickel per cm² of skin per week. In principle, the percentage of nickel an alloy contains is unimportant. What matters is how much nickel it releases into the skin. NOMOS Glashütte uses 316 L stainless steel for all cases and clasps. This stainless steel is not absolutely nickel-free, but it does not release nickel: The admixture of nickel is about twelve percent. This means less than 0.2 mg of nickel per µg/cm²/week is released – far less than the limit called for by the medical profession. Other stainless steel alloys have a lower percentage, but they release more nickel into the skin. However, allergies don’t care much for rules and limits. Although we very rarely hear about cases where the materials we use have caused allergic reactions, they can never be ruled out entirely. We advise people who are extremely allergic to consult a specialist to help them select a material that is least likely to cause an allergic reaction. Our aim is to use materials that can generally be best tolerated. This does not only apply to steel. The watchstraps we use are tanned using a complex, purely plant-based process lasting several months. So far, we only know of two cases where a person developed an allergic reaction to NOMOS watches or straps. That’s two in 20 years.
Can I go swimming wearing my watch, or take a shower or sauna?
Until a few years ago, our watches bore the inscription “water resistant to 30 m”; in the case of sport models, it was “water resistant to 100 m.” These are DIN standard specifications and unfortunately they repeatedly led to confusion, because “water resistant to 30 xm” doesn’t mean that you can dive 30 meters underwater wearing your watch. According to DIN standards, watches can be considered watertight if they are proof against water, sweat and rain and can weather 30 minutes in one meter of water. Because of arm movements and changes in the pressure conditions they cause, swimming and, in particular, diving are not recommended. Today, normal NOMOS watches bear the new and technically more useful water resistance rating “to 3 atm” while the sport and the club models have the inscription “to 10 atm” NOMOS watches that are watertight down to 10 atm can also be worn in a swimming pool, sauna or shower. However, temperature variations, chemicals, etc. always affect watches adversely. They attack the rubber seals and eventually lead to a deterioration or loss of water resistance. That is why you should have your watch checked for water resistance once a year (your dealer can do it in next to no time). And to protect your strap as well, we recommend you remove your watch in the sauna or pool.
How, how often and when should I wind my watch?
If you wear a NOMOS self-winding watch, then you don’t have to do much at all: generally, a self-winding watch should be able to gain all the energy it needs through the motion of your arm. The spring in the self-winding mechanism will tighten regardless of how you move. If it does stop after you haven't worn it for a while, just turn its crown a few times and the watch should start running again.
For owners of manually-wound watches, we recommend regular winding – preferably in the morning. That gives the watch enough energy to run reliably throughout the day. Again, all you need to do to wind up the watch is turn the crown clockwise (towards the 12). After just a few rotations, the balance will start to move. Continue to turn the crown until you notice obvious resistance. Once your watch is fully wound, it will run for about 43 hours – in other words, for around two days without needing to be rewound. Watches with dates need to be rewound slightly more often (around once every 42 hours) because switching the date also takes a little energy from the watch.
Will it damage my NOMOS automatic watch if I always wind it manually?
With some movements, the wheels all turn almost as far as the rotor when the watch is wound by hand. You also notice that when you are winding it. However, the designers of NOMOS self-winding watches have fitted their pieces with a clutch, which means that all the self-winding mechanism components stop moving during manual winding, thereby preventing wear and tear. So you can happily wind your NOMOS self-winding watches by hand every day if you want – and if you ever forget to, then the automatic movement will quietly do it for you.
How do I set the date on my NOMOS watch?
Our watches do not have any so-called quickset mechanism, but changing the date is still quick and easy: just pull the crown out and turn the hand forwards until the date changes, then turn the hand back three or four hours until you hear a slight click. Move the date on further by repeatedly moving the hands on by at least three hours and keep on doing so until you have reached the correct date. If it’s after midday, you have to move the hand past the 12 to stop the date jumping on to the next day when it’s only 12 noon. This may sound a bit complicated, but it’s actually quite simple. Just try it out. Everything is also described in detail in the small guarantee book you received with your watch.
