A large watch, generously proportioned. This watch knows the time and the date, winds itself, and its numerals and hands shine in the dark. What’s more: It is particularly water resistant—to 20 atm, so 200 meters. And it wears the summer sky on its dial in siren blue.

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.
