Ahoi in a somewhat smaller size, thanks to the ultra-thin automatic caliber DUW 3001 with the NOMOS swing system (visible through the sapphire crystal glass back). Ahoi neomatik is water resistant to 20 atm, so suitable for diving, equipped with a crown guard, its back fixed with six screws—all in all: elegant, sporty, and classic in a diameter of 36 millimeters.
