The **DUW 4301** is a [[manually wound]] movement with [[power reserve indicator]] from [[Nomos]]. It is an evolution of its predecessor, [[Nomos Gamma]], and was introduced in [[2014]].

===== 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 [[2014]], the Nomos DUW 4301 movement is a [[manually wound]] movement with [[small seconds]] at 6 00 and a [[power reserve indicator]] at 1 00. 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 17 [[jewel]]s.

The [[power reserve indicator]] is placed inside the main plate, requiring no additional thickness, and the movement is reduced in overall size. It is 23.3 mm in diameter and just 2.8 mm thick.

Calibre DUW 4301 replaced the [[Nomos Gamma]] movement, with which it shares many components.

===== Applications =====
  * [[Nomos Tangente power reserve]]
  * [[Nomos Tegra Kleene]]

===== Movement Family =====
This movement is part of a family of Nomos movements produced since [[2014]]. The movement is made [[in-house]], including the [[Nomos Swing System]].
