NOMOS Ahoi Neomatik Signalrot with Sapphire Crystal Back
Finally: Ahoi, a little smaller. The ultra-thin automatic caliber DUW 3001 is what makes it possible. And it is the only difference between this and the larger Ahoi models. Ahoi neomatik is water resistant to 20 atm (which makes it suitable for diving), equipped with a crown guard, has a back held firm with six screws—and is beautiful, elegant, and has a classic diameter of 36 millimeters.
