Smart and subtle: Ludwig is the secret Wunderkind of the NOMOS collection. But despite its obvious academic credentials and command of Latin, this watch remains appealing and understated—as well as so slender that it will steal the heart of those with even the finest aesthetic sensibilities. Visible within though the sapphire crystal glass back: the hand-wound DUW 4001 caliber, crafted in Glashütte.
Impression
Ludwig at its original and best—with the classic NOMOS diameter of 35 millimeters. It has been flattering men’s and women’s wrists alike.

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.
