Durability and clear readability in a 41 mm diameter size that is comfortable to wear: you will find these properties in the U50 series. 

Visually, the diver’s watch is noticeable for the striking design of its matte-black dial and a display that concentrates on the essentials. When it comes to its features, we also focus consistently on typical SINN characteristics. The case and crown are thus made of high-strength seawater-resistant German Submarine Steel. This type of steel stands out not only for its extremely high strength and exceptional non-magnetic properties but also for its especially high resistance to seawater. We have designed the rotating bezel so that it is captive in the case. As it may experience high levels of stress during use, we have also hardened the surface using TEGIMENT Technology, making it especially scratch-resistant.

These features make it clear that the U50 is perfectly suited to diving use – a fact that has been verified by the classification company DNV. DNV verifies and certifies pressure resistance to a diving depth of 500 metres (= 50 bar) and temperature resistance and functionality in accordance with the European diving equipment standards.

Limited to 1,000 pieces – documented on the case back – and with a high-quality intricate finish. These features alone ensure that the U50 DS will turn heads. The dial is certain to spark particular interest. Thanks to the irregular finish, the wearer can enjoy an exciting interplay of colours as the base material reflects varying nuances of light on different parts of the dial. And the real kicker: thanks to this, each watch is unique. Each machining process produces a truly unique impression. Despite this, the design does not impair clear readability. This is also thanks to the striking design and minimalist display.

The U50 DS is regarded as a robust and precise timepiece by watch enthusiasts. It is based on the principle of maximum reliability. This performance promise is fulfilled by the use of safety-related equipment. For example, the case is made from high-strength seawater-resistant German Submarine Steel. Experts will recognise immediately that this gives the watch exceptional strength and outstanding non-magnetic properties. The captive rotating bezel prevents the loss of set times. And as the watch may be exposed to particularly harsh conditions, we have also equipped the case and rotating bezel with TEGIMENTTechnology to ensure exceptionally high scratch resistance. 

Furthermore, the U50 DS was put through its paces by the DNV. Pressure resistance was verified and certified to a diving depth of 500 metres (= 50 bar), as was temperature resistance functionality in accordance with the European diving equipment standards.
