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 ground 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 dial is therefore a unique piece – the impression achieved during the machining process can never be exactly repeated, making it completely individual. 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 GL 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.
