Tangomat GMT knows the time where you are and everywhere else in the world: Sydney, Denver, Moscow, Alaska—airport codes denote the 24 time zones in Tangomat, and are helpful even when you’re at home but, for example, in a long-distance relationship. At the push of a button you’re there and back again, even before your loved one down under calls to say good morning.

Impression
At first glance, this watch appears like a large Tangente. But only at first glance. Tangomat GMT is much more—equipped with the world time caliber DUW 5201, this watch has a taller profile, for robust wrists with substance.

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.
