This watch does its job with ease. And it suits every occasion. Our highly water-resistant watch Ahoi is now available with a diameter of just 38.5 millimeters and—for the first time—with the innovative and super-slim Neomatik caliber DUW 6101. This in-house automatic movement features our patented date mechanism. Even with a sapphire crystal case back, the case measures just 9.9 millimeters in height. The result is a most elegant interpretation of a sports watch. Every glance at the dial brings the sense of limitless freedom—as refreshing as a brisk sea breeze.
