Theodor Prenzel (right) and Mirko Heyne, heads of the Research & Development Department, have invested a good 1.5 million minutes on the development of the new automatic caliber DUW 3001.

In DUW 3001, the NOMOS balance bridge takes the place of the balance cock. It elegantly ensures the stable positioning of the balance.

Ultra slim: DUW 3001 measures a mere 3.2 millimeters. It is thinner than almost all other movements that that run on their own power.

Research and development in the NOMOS Glashütte Atelier

Seen from the outside, mechanical watches have not changed a lot in the past 200 years: Gears, screws, springs, pinions, and levers were always used in them and still are. And yet, many things are different. A boutique watchmaking firm that takes pride in itself naturally does not rest on its laurels. Modified alloys have better frictional properties. New cog shapes ensure that gears rotate more easily. High-precision parts make new complications possible.  

We at NOMOS Glashütte have always valued both tradition and progress—with the date function, for instance. The date ring was mounted on rubies and set around the movement, which kept the watch elegant and flat. This NOMOS design is protected by a patent. Another example of our watchmaking skill is the crescent-shaped power reserve indicator: This mechanism comes with just a few extra components and has also been patented. We were able to present our first in-house built automatic movement in 2005, which was a significant event. And the first NOMOS world time function came out a few years later: The DUW 5201 movement ticks inside both the Zürich Weltzeit and the Tangomat GMT models—making them de facto 24 watches in one.  

In order to improve continuously, NOMOS works in cooperation with the Technical University of Dresden and the Fraunhofer Institute. This has led to the development of our own gear wheel train, for example.
