Tangomat Glück auf, a special model for our German retailer Juwelier Rüschenbeck, is a very fine tribute: The traditional greeting between miners “Glück auf!” finds its roots in the Ore Mountains region, where NOMOS Glashütte also comes from, and refers to the long tradition of mining in the Ruhr area—the home of the Rüschenbeck family business. And that’s why 125 pieces of this limited-edition model are exclusively available at Juwelier Rüschenbeck and here in the NOMOS Store.

Caliber
The first NOMOS automatic caliber and the one with which NOMOS Glashütte launched its in-house caliber production in 2005. Since then, it has been ticking with outstanding winding accuracy—and now with our NOMOS swing system too, which is to say: with independence at its heart.
