The NOMOS caliber Zeta does everything itself: With this motor, found at the heart of NOMOS watches such as Tangomat and Zürich date, you neither have to think of winding nor today’s date. This automatic caliber features NOMOS’ patented date mechanism.

The fact that the date ring is placed around the movement means that the caliber is slightly larger, but it also remains slender and elegant. In terms of winding rate and accuracy, Zeta is of course just as competent as its fellow caliber Epsilon, which is the non-date version.
