====== DUW 4101 ======
The **DUW 4101** is a [[manually wound]] movement with [[date]] from [[Nomos]]. It is an evolution of its predecessor, [[Nomos Beta]], and was introduced in [[2015]].

===== Overview =====
The [[2005]] introduction of the [[Nomos Alpha|Alpha movement family]] was an important turning point for Nomos. Although based on the preceding [[Nomos 1 TSP]], it was largely constructed [[in-house]] rather than being a refinished [[ebauche]]. This was followed in [[2006]] by the Nomos Epsilon, the first Nomos movement with [[automatic winding]]. The next great leap forward for Nomos was the [[2014]] introduction of the [[Nomos Swing System]], an [[in-house]] [[assortment]], in movement [[DUW 4401]]. Over the next few years, this technology moved to other models in the Nomos movement family.

Introduced in [[2015]], the Nomos DUW 4101 movement is a [[manually wound]] movement with [[small seconds]] at 6 00 and a [[date wheel]]. Like other Nomos movements, it is made in a [[three-quarter plate]] design, plated with [[rhodium]] and decorated with [[Glashütte ribbing]] and [[perlage]]. The [[ratchet]] and [[crown wheel]]s are decorated with a [[Glashütte sunburst]] pattern and [[blued]] screws are used. It features [[Glashütte stopwork]], [[Incabloc]] shock protection, and 23 [[jewel]]s.

The DUW4101 movement adds an unusual and patented date display like the [[Nomos Beta]]. Typically, a [[date wheel]] and associated gears are stacked below the [[mainplate]] between the rest of the watch movement and the [[dial]]. However, this makes these movements more bulky and thick. Instead, Nomos places the date ring around the movement, with the switching mechanism integrated into the movement itself, making the DUW 4101 just as thin as non-date versions at 2.8 mm. However, this adds to the diameter of the movement, bringing it to 32.1 mm.

Calibre DUW 4101 replaced the [[Nomos Beta]] movement, with which it shares many components.
