Nomos Ahoi Neomatik Atlantik Mens Watch 567Ahoi Neomatik Atlantic—a versatile automatic watch, equipped with the innovative caliber technology of the high-precision Neomatik DUW 3001 movement. The caliber, developed by NOMOS, measures just 3.2 millimeters in height—the same as nine stacked postage stamps— making it remarkably slender. The time is kept by the proprietary escapement, the famous NOMOS swing system. With a case diameter of 36 millimeters, Ahoi Neomatik Atlantic is the smallest of the Ahoi Atlantic edition models. The watch is waterproof up to 20 atm.
