Tetra Ochra
Description
Drawn from pigments once treasured by artisans and ancient Egyptian royalty, Tetra Ochra glows with golden light. With its strikingly square case, this watch balances contemporary aesthetics with artisanal tradition. It also represents a philosophy—that true brilliance is found in the harmony of craft and character. The hand-wound caliber DUW 4001 at work within illustrates this with meticulous precision.

Safety instructions
NOMOS uses 316 L stainless steel for all steel cases, bracelets and clasps. 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.
