For sporty people, adventurers, and all those who dream of living a little more: automatic timepiece Ahoi in Atlantic blue is wild and wise, in this version with the extra large date display as well. The dial creates an elegant contrast with the golden hour and minute hands, and thanks to superluminova they still tell time long after sunset—or 200 meters beneath the waves.
Impression
Elegance can be sporty too: The automatic Ahoi model is one of the largest from NOMOS Glashütte, measuring 40 millimeters in diameter. A timepiece that adds presence to the wrist—and in Atlantic blue, a little drama as well.
