Limited to 500 pieces, the SINN U1 DS model features a grinded dial with an irregular, decorative pattern. It offers 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.
The case and crown of the SINN U1 DS watch are made of high-strength seawater-resistant German Submarine Steel, which enjoys outstanding non-magnetic properties.
Its case surface and the captive diver’s bezel with minute ratcheting have also been hardened with TEGIMENT Technology, leaving them especially scratch-resistant.
Suitable for professional diving, 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.
This 44mm timepiece houses a Swiss made SW 200-1 self-winding movement. The triangle marker of the bezel, all the 12 hour-marking indices on the dial and the hands (hour, minute and second) are embedded with luminescent material for enhanced visibility. The dial also hosts a date window at 3H. The crown is positioned at 4 o’clock to prevent pressure on the back of the hand.
