In soft nude, Tetra radiates sophistication. The highlight of its small seconds dial is a vibrant yellow hand. On a velvety gray strap made of vegan velour, this delicate and at the same time highly striking mechanical watch beautifully underscores any style. The Alpha caliber manufactured with manual winding ticks away on the inside. Valuable and precise—shaped by the unique art of watchmaking from Glashütte.
Impression
With corners, edges and a full gamut of expression: a watch celebrating the fullness of life.

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.
