The future is blue—siren blue: This Ahoi is powered by automatic caliber DUW 3001, the tenth proprietary movement from NOMOS Glashütter. Ultra-thin, highly precise, the perfect symbiosis between handcraft and high-tech. It means this watch can tick in an entirely new size, as slender as a hand-wound, in the classic diameter of 36 millimeters. Good to know: Ahoi neomatik signalblau has a license to dive. To 20 atm, so 200 meters, it stays tightly sealed, thanks to crown protection and the back fixed with six screws.You can look good diving in deep blue too—instead of a light gray textile strap, we’ll deliver your NOMOS timepiece with a blue-black one upon request.
