A watch with a story: As a model in our display collection, this watch has come with us to a number of trade fairs and so is no longer entirely brand new. Having been carefully refurbished, it is waiting for a new set of duties—on your wrist.
Prizes and awards
Good Design, iF Award, Goldene Unruh: It seems as if Ahoi receives another award every time it drops anchor.







Impression
Contemporary sportswear Elegance can be sporty too: The automatic Ahoi model is one of the largest from NOMOS Glashütte, measuring 40 millimeters in diameters. A timepiece that adds presence to the wrist.

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.

Caliber
The first NOMOS automatic caliber and the one with which NOMOS Glashütte launched its in-house caliber production in 2005. Since then, it has been ticking with outstanding winding accuracy—and now with our NOMOS swing system too, which is to say: with independence at its heart.

Outstanding materials
Designed in Berlin, elaborately produced, and polished by hand, the NOMOS winged clasp exudes elegance through its beautiful minimalism.
The textile strap is tailor-made for NOMOS Glashütte in France. It sits comfortably on the wrist—and as elegant as it is, this strap is (of course!) also suitable for a swim.

Beautifully presented
Our automatic timepieces come in an elegant leather wallet—the perfect companion for weekend trips and world tours. The black, full grain leather is wonderfully soft and protects your timepiece beautifully.
