Tangente date power reserve
Description
The multiple prizewinning design classic from Glashütte with a hand-wound caliber and patented power reserve indicator that reminds the wearer when to rewind the watch. German efficiency! Another NOMOS patent: the extra-large date. The date ring is set around the movement, while the power reserve mechanism is integrated into the mainspring barrel—so everything remains elegantly slender, despite the additional complications.

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.
