In-house built caliber Alpha

The Alpha caliber is NOMOS Glashütte’s highly acclaimed classic. It was our first movement—and the one that still powers more of our watches than any other. Robust, accurate and reliable, it ticks inside Tangente, Ludwig, Tetra, Orion and Club and all the watches in our 33 Series.
