Nomos Gamma

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 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) 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, Epsilon, Zeta, and 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".
