[[Nomos]] **Gamma** (γ) is a [[manual winding]] movement with [[power reserve indicator]]. It was introduced in [[2007]] and retired in [[2016]], succeeded by [[DUW 4301]].

===== 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]]. The gear train is similar to the classic [[Peseux 7001]], but was placed in a new enclosure based on the classic [[Glashütte]] [[three-quarter plate]] design. Nomos updated many of the components, adding [[hacking seconds]], and completely reworked the finishing with [[rhodium]]-plated surfaces, [[blued screws]], [[Glashütte Stripes]], and Glashütte [[solar grinding]] or [[Langeleist-Perlage]].

Calibre Gamma (with [[power reserve indicator]]) was released shortly after [[Nomos Alpha]] (without [[date window|date]]) [[Nomos Beta]] (with date), and [[Nomos Delta]] (with date and power reserve indicator). All three are hand-winding movements. In [[2006]], Nomos followed with a family of [[automatic]] movements, [[Nomos Epsilon|Epsilon]], [[Nomos Zeta|Zeta]], and [[Nomos Xi|Xi]], with similar features. Alpha and Gamma are smaller than the others, however, at just 23.3 mm diameter and 2.6 or 2.8 mm thick.

The [[power reserve indicator]] is integrated into the [[mainplate]] of the movement, adding no additional thickness. It shows the remaining power in the mainspring, serving as a reminder to wind the watch.

A direct successor to the Nomos Gamma was introduced in [[2014]], the [[DUW 4301]] featuring the [[Nomos Swing System]]. The Gamma calibre was phased out after this and removed from the catalog in [[2016]].

This movement is officially named using the Greek letter "γ", but Nomos often writes it as "Gamma".

===== Applications =====
  * [[Nomos Tangente power reserve]]
  * [[Nomos Tetra power reserve]]

===== See Also =====
This movement is part of a family of Nomos movements produced since [[2005]]. The movement is partially made [[in-house]], though the [[assortment]] is supplied by a third-party. It was supplanted by the in-house [[Nomos Swing System]] family starting in [[2014]].
