Nomos Glashütte caliber Zeta
You don’t want to have to think about winding your watch? Or about changing the date? Then you’ll need the Zeta caliber, the movement you can find in Tangomat Datum and Ahoi Datum—among others. Zeta is an automatic movement further enhanced by NOMOS’ patented date mechanism. The fact that the date ring is set around the movement has made it slightly bigger, but keeps it as flat and elegant as ever. Of course, this movement provides the best winding performance and rate accuracy.
