How exact is my watch?

Both types of mechanical watches (hand-wound and automatic watches) always exhibit an element of tolerance as far as accuracy is concerned. This depends on the way a timepiece is worn, for example. Variations in temperature and air pressure, minor jolts and irregular winding can also have an influence. Mechanical watches from NOMOS Glashütte achieve an accuracy of less than ten seconds deviation per day. To ensure this, we regulate our mechanical calibers in six positions over the span of seven days. NOMOS Glashütte watches must achieve the best results in all dial and crown positions.

How are NOMOS watches adjusted?

Fine adjustment regulation (something that few manufacturers offer at all) ensures the greatest possible accuracy. Before leaving NOMOS Glashütte, all watches are thoroughly put through their paces—the NOMOS controllers spend several days testing them in six different positions to ensure each watch is working properly. NOMOS Glashütte uses three different regulation systems: the Triovis fine adjustment system, the DUW adjustment with the NOMOS swing system, as well as the swan neck fine adjustment found in our gold models, Lux and Lambda.

What is the NOMOS swing system?

The swing system, also known as the escapement, assortiment, or reglage, is the heart of a mechanical watch and comprised of the balance, balance spring, pallet wheel, and pallet. It sets the pace and ensures that the watch ticks accurately. It is a declaration of independence for NOMOS Glashütte to be able to produce its own swing system, and a work of considerable watchmaking skill.

Is the NOMOS swing system at work in all NOMOS models?

It will be in the future. The NOMOS swing system will gradually be extended to all current watch models.

Allergies: Does NOMOS use nickel-free stainless steel? And what other materials?

The so-called "nickel regulation" has been in effect since June 2000. It says that objects that touch the skin directly and for extended periods of time may only give off 0.5 micrograms of nickel per square centimeter of skin per week. In general, it doesn't matter how high the percentage of nickel in any given alloy is. Much more important is how much nickel is passed on to the skin.

NOMOS uses 316 L stainless steel for all cases and buckles. This type of stainless steel is not fully free of nickel, but it does not pass nickel on to the skin; the amount of nickel in the alloy is about 12 percent. Thus, the amount of nickel passed to the skin is less than 0.2 micrograms per square centimeter per week and far below the medicinally acceptable amount. Other stainless steel alloys might have a lower percentual amount of nickel in the alloy, but they pass more of it on to the skin.

Nevertheless, it is a fact that allergies don't give a hoot about regulations and limits. We only hear very, very rarely of cases where people were not able to tolerate the materials we use. Unfortunately, however, allergic reactions can never be ruled out all together. We advise people who are very sensitive to choose—in consultation with his or her physician—a material which, in all probability, will not provoke an allergic reaction.

It is our goal to use the best possible materials for you. And this is not only true for the steel we use. For example, our straps are tanned in an elaborate manufacturing process using vegetable lye only.

Can I swim or shower with my watch?

Particularly water-resistant watches have this feature noted on their casebacks. If your NOMOS watch has the addition 30 atm or 20 atm on its back then, according to the DIN standard, you can go diving with it. The description 10 atm reveals that your watch is suitable for swimming and snorkeling; 5 atm means that you can shower with your watch on. All other NOMOS watches are protected to 3 atm and generally prefer to stay dry; they are splashproof, so wearing them while washing your hands will not cause them any problems, but you should take them off before a dip in the pool. It is recommended to have the water resistance of a mechanical watch checked once a year by a retailer. It only takes a moment.

Please note: The three models Ahoi, Tangente Sport, and Club Sport come with a screw-drown crown. Please remember to screw the crown back in after use—as this is the only way to ensure your watch stays water resistant. To do so, gently push down the crown in its default position and turn it clockwise until you feel some significant resistance. The crown should never be wound while underwater.

How, how often, and when should I wind my watch?

If you wear a NOMOS automatic, you don't have to do much. Your watch winds itself using the motion of your arm. The spring in the automatic movement tensions itself regardless of how the arm is moving.

We recommend to the owners of manually wound watches to wind your watches regularly—best is every morning. Then it will have enough energy for the whole day to withstand all of the trials and tribulations you might undergo.

Wind your watch by turning the crown clockwise between your thumb and forefinger until you feel a clear point of resistance. Once your watch is fully wound, your NOMOS has a power reserve of 43 hours. Without having to rewind, it will run for two days. Only the watches with date have a little less (42 hours), as the changing the date costs the watch energy.

Does it damage my NOMOS automatic watch if I always wind it by hand?

No—because NOMOS automatic watches have been installed with a clutch mechanism so that all parts in the movement stand still when it is wound by hand (which is also why you don’t feel any resistance while winding). The new extra-thin automatic movements DUW 3001 and DUW 6001 work slightly differently: When you wind them, you will soon notice that the resistance of the crown increases—this means that the watch has been given enough energy. The rotor stops when it is fully wound, which protects the fine caliber against wear. Either way: You can wind your automatic NOMOS watch without any worries, but the self-winding mechanism will also take care of this job for you.

I have a watch winder. What is the best setting for my NOMOS watch?

The best setting is 650 turns per day with alternating rotation direction.

What happens when my watch becomes magnetized?

There are a great number of magnetic fields in our everyday environment—including anywhere where electricity is present, such as close to personal electronic devices. Unfortunately, these magnetic fields can have a negative effect on a mechanical watch: they can affect the escapement parts of the caliber, stopping it from working properly. This is usually noticeable by a watch suddenly gaining time. However, losing time or stopping all together can also be a consequence of a watch becoming magnetized.

If you suspect that your watch has been magnetized, ask your retailer if they have a demagnetization machine. This can demagnetize your watch in only a few minutes, if required. Of course, you can also send your NOMOS directly to us in Glashütte. However, please note: since magnetization is not a defect of the watch, we are unfortunately unable to carry this service out under guarantee.

Can I as a consumer make special requests?

In order to keep our collection as clear and small as possible, we can only comply with certain requests for individual wishes. For example, it is possible to laser an engraving on the case back of your watch. Upon request we'd be glad to send you an estimate. Though we won't change the dial or handle similar requests.

Can my steel watch also be equipped with a sapphire crystal case back?

In general, every NOMOS watch except Tetra 27 can be refitted with a sapphire crystal case back. We’ll be happy to send you an offer upon request.

Can I have the NOMOS swing system built into my watch at a later date?

The Nivarox escapement—which we have previously used in all our watches and are still using in some of them—is of excellent quality, ensuring outstanding accuracy. For this reason, we do not offer the option to exchange this escapement for the new NOMOS swing system; this also applies during servicing.

What is the benefit of registering my watch online?

In the event that you lose your watch, it can be very helpful if your watch and its serial number are listed with us. In fact, it happens quite frequently that an honest finder or the police contact NOMOS Glashütte about a watch that has been found. In such cases, we make sure that your watch finds its way back to you.

What happens if my watch goes missing?

Please report the loss to us. If your watch was stolen, report it to the police and send us the contact details of the police station, along with the case reference number. This means that you can be more quickly reunited with your watch should it return to us.

Why are some NOMOS watches labeled with “Made in Germany” and others with only “Germany”?

The inscription “Made in Germany” began appearing on our watches in mid-2003. Later, when we reorganized production and began making our own in-house movements in April 2005, we also shortened the lettering on the face to read simply “Germany.” After a while, we changed this diminutive label back to “Made in Germany” because we realized it actually does have a nicer ring to it.
