Tradition and innovation: to ensure that the special edition of Ludwig for the 375th anniversary of the Peace of Westphalia truly links history with the present, one of the four models is equipped with an automatic caliber. The fact that progress comes about through movement is indeed a peace-promoting insight—and the exclusive traditional features of the classic watch look ever so elegant on an automatic watch. High-precision mechanics of protected origin throughout Europe—a testament to time from Glashütte, created in cooperation with the jewelers Freisfeld and Oeding-Erdel in Münster and Osnabrück.

Safety instructions
NOMOS uses 316 L stainless steel for all cases and buckles. This type of stainless steel is not fully free of nickel, but it does not pass nickel on to the skin; the amount of nickel in the alloy is about 12 percent. Thus, the amount of nickel passed to the skin is less than 0.2 micrograms per square centimeter per week and far below the medicinally acceptable amount. Other stainless steel alloys might have a lower percentual amount of nickel in the alloy, but they pass more of it on to the skin.

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.
