The NOMOS Tetra² Hasenohr features a stainless steel case of 29.5*29.5mm with a closed case back, hiding its hand-wound Alpha movement from view. The dial is 'Hasenohr' green.
The Alpha caliber is NOMOS Glashütte’s highly acclaimed classic. It was our first movement—and the one that still powers more of their watches than any other. Robust, accurate and reliable, it ticks inside Tangente, Ludwig, Tetra, Orion and Club and all the watches in the 33 Series.
