The U1 DS model, limited to 500 pieces, is a very special timepiece in our range. The diving watch owes this to its dial, which we have grinded with an irregular, decorative pattern. As a result, the wearer enjoys an exciting play of colours as the base material on some parts of the dial reflects different nuances of light. Every watch is therefore a unique piece – the impression achieved on the dial during the machining process can never be repeated. The design still allows for perfect readability – thanks to the striking form and minimalist display
Alongside these optical characteristics, the watch also boasts high-quality technical features. The case and crown are made of high-strength seawater-resistant German Submarine Steel, which enjoys outstanding non-magnetic properties. The surface of the case and the captive diver’s bezel with minute ratcheting have also been hardened with TEGIMENT Technology, leaving them especially scratch-resistant.
The U1 DS guarantees reliability and precision, even under extreme conditions. The DNV has verified and certified the U1 DS’s pressure resistance to a diving depth of 1,000 metres and its temperature resistance and functionality in accordance with the European diving equipment standards.
