Nomos Glashutte Watch Ahoi Atlantik Sapphire Crystal 552. Like the already renowned Ahoi, this new version is sporty, dynamic, and ready for adventure: With an Atlantic blue dial and rose gold hands, Ahoi Atlantik shines even at the bottom of the ocean thanks to superluminova. The new watch is water resistant to 200 meters. Ticking away within is the Epsilon caliber, the comfortably wearable and elegant textile strap that drys quickly.
