Striking lines, minimalistic displays and clear readability define the diving watches in the U1 series. A special feature of the U1 B is the matt-blue dial.
The luminous white indices and hands provide a strong contrast to the blue dial, ensuring outstanding readability at all times. The distinctive colours of the U1 B are further emphasised by a blue silicone strap.
The case made of high-strength German Submarine Steel is extremely seawater-resistant and also possesses the highest level of non-magnetic properties. Hardened using TEGIMENT Technology and therefore especially scratch-resistant, the captive diver’s bezel with minute ratcheting is virtually impossible to detach by being knocked off.
DNV verifies and certifies the pressure resistance of the U1 B to a diving depth of 1,000 metres and its temperature resistance and functionality in accordance with the European diving device standards. Users of the U1 B can thus be assured that they are wearing a precise and reliable diving watch on their wrist.
