This timepiece, with the sensational NOMOS caliber DUW 5001 ticking within, is bound to impress mermaids—even those 200 meters beneath the waves—and colleagues in the office, quite automatically so. Ahoi stays secure on the wrist with a woven textile strap, a homage to childhood days spent at the outdoor swimming pool. And the white silver-plated dial with a dash of light blue tells of a summer eternal. How wonderful!
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.

Fabian has a wrist circumference of 18.5 cm and a strap length of M.

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.
