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.
