Nomos Epsilon

The Epsilon (ε) is the first automatic movement from Nomos.

Based on the standard manual winding Nomos Alpha movement, the Epsilon is itself the basis of a family of automatic movements from the manufacture.

As with all Nomos movements, this calibre is executed in three-quarter plate with hacking seconds, Glashütte Stripes and solar grinding or Langeleist-Perlage.

The first self-winding movement by Nomos

Epsilon (without date) or Zeta (with date) is the first self-winding movement from Nomos. Because of the creation of this movement, Nomos can truly be called a manufacture, since it was completely designed, developed, and built in-house.

This calibre includes a large 31 mm central rotor which moves around the edge of the movement, allowing it to remain quite thin. It includes a bi-directional winding system. The balance wheel is very large, a traditional watchmaking technique to increase accuracy.

Epsilon version 2

The first version of the Epsilon movement had 24 jewels. In May 2007, Nomos switched to a new version with 26 jewels. One wheel in the automatic winding system was set in two extra jewels, allowing better winding efficiency and durability thanks to reduced friction.
