Not to be overlooked: Tetra neomatik red. The opaque surface of the glossy enamel-like dial reflects the light, increasing the color intensity of this extravagant automatic watch. Precisely timed rhodium-plated hands sweep across the rectangular dial. As the lettering under the signature indicates, a top-class automatic movement is at work in the watches of this limited edition. The neomatik DUW 3001 caliber is equipped with the NOMOS swing system—the famous proprietary escapement that achieves the very best accuracy in chronometer tests.

Beautiful things


Outstanding materials
Designed in Berlin, elaborately produced, and polished by hand, the NOMOS winged clasp exudes elegance through its beautiful minimalism.
All things considered: a straightforward watch needs an equally straightforward clasp. The NOMOS deployant clasp, designed in Berlin, is made of highly polished 316L stainless steel and is unobtrusive. The clasp is included at no extra charge with the four models of the Tetra neomatik – 175 Years Watchmaking Glashütte limited edition.

Beautifully presented
A black case, made of fine leather, protects the watch during shipping and also fits easily in your luggage.
