Nomos calibres

Glashütte watch maker Nomos has progressed to a full manufacture over the last two decades. The company began with a refinished version of the Peseux 7001 before creating their own movement components, designing their own movement families, and building an in-house assortment, the Nomos Swing System. Today, they are one of the few companies that manufactures every movement component in-house.


From the beginning, Nomos was involved in re-working the watch movements they used. Their earliest watches used the traditional hand winding small seconds Peseux 7001, but they began modifying the movement in 2002. They added Triovis fine regulation, renaming the movement Nomos 1 T and beginning a family. They added hacking seconds for the Nomos 1 TS, a and a date wheel for the Nomos 1 TSD. The next major advance was the replacement of the multi-part Swiss movement plates with a traditional Glashütte three-quarters plate for the Nomos 1 TSDP and Nomos 1 TSP. Finally, they added a power reserve indicator in 2004 for the Nomos 1 TSDPG.

Nomos was already working on their next major advancement, however. In 2004 they announced that they would produce a movement made from in-house components. The Nomos Alpha was the first, replacing everything apart from the assortment with parts made by the company. This was followed by updated versions with date (Nomos Beta) and power reserve indicator (Nomos Delta). These used a patented design that placed the date wheel outside the movement plane, resulting in a thinner overall movement.

In 2006, Nomos released their first automatic movement, Nomos Epsilon and Nomos Zeta (with date). These used a rotor wider than the movement itself, similar to the company's date mechanism, reducing overall thickness. Another major advance for this period was the innovative world time watch series using the Nomos Xi. These automatic movements proved incredibly popular and remain in production as of 2019.

As Nomos gained expertise in movement construction, they took on work from other companies. Many of their movement designs appear in watches from Wempe, for example. And Nomos also created their own “haute horlogerie” movement family with a swan neck regulator and double barrel power. These new in-house movements were given a new name, Deutsche Uhrenwerke or DUW. For this series, DUW 1001 is a round movement and DUW 2002 is tonneau shaped.

The next major advance for Nomos was the creation of their own assortment, the Nomos Swing System, in 2014. This was a major advance for the watch industry, as very few companies have mastered the construction of a balance wheel and escapement. The first Swing System models were the hand winding DUW 4401 and DUW 4301, but an automatic version was quickly introduced as well, DUW 5201. These were niche movements, allowing the company to get up to speed on production before ramping up with the more mainstream DUW 4101, DUW 5101, and DUW 5001. These quickly displaced the old “Alpha” family movements, and it is expected that Nomos will retire those in the next few years.

2015 saw the introduction of the “Nomos neomatik”, an entirely new small and thin movement with the Nomos Swing System. These watches are marketed specifically for this extra-thin movement and use the DUW 3001 or DUW 6101 movement.
