Nomos Ahoi Datum (551)

Ahoi from Glashütte! Forty millimeters across, this watch is extra-large and has an extra-large date to match. Being water-resistant down to 200 meters means it's a great accompaniment for swimming and sport—and, with a blue-black waterproof textile strap, it is ready for each and every adventure. The in-house built Zeta caliber works away reliably, visible through the extra-strong sapphire crystal glass back.
