A New Tetra from Nomos

This is the Tetra Nematik. It was, without a doubt, one of my favorite offerings at BaselWorld this year.

One of my favorite aspects, and very sorry to be so attached to the physical, is the playful use of color  on the outer edges of the dial with the 5 minute/second increments punctuated in a light blue for the white dial version and green on what Nomos describes as a deep blue dial.

The case is a larger interpretation of the previous versions of the Tetra.  It measures 33mm x 33 mm.  See through case back.

The movement is the DUW 3001.  It is an in-house creation from Nomos.  Self-winding, featuring the now famous Nomos Swing System.  The advertised power reserve is 42 hours.
