New from NOMOS Glashütte: duo. These elegant, two-hand models are 33 millimeters in diameter—or for Tetra 27 duo, with a side length of 27 millimeters. Perfect for more slender wrists and still highly precise, even without the small seconds. The NOMOS caliber Alpha.2 sets the pace inside.

Ref. 405

Perfectly proportioned for slender wrists, the Tetra Duo has a side length of approximately 27 mm and a height of 6 mm. Alpha.2 is based on the NOMOS highly precise in-house caliber, Alpha. Though with a small—but important— difference: The caliber has a modified second wheel with a smaller staff. Alpha.2 keeps time in the smaller two-hand versions of Tangente, Orion, Ludwig, and Tetra. The light-coloured velour leather strap discreetly lets the watch attract attention.
