Sinn (DE) U50 S – Ref. 1050.020 – The Black Diving Watch Made of German Submarine Steel On Silicone Strap

“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 with Black Hard Coating on a tegimented basis. 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 S 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. Listed price includes the red silicone strap with black butterfly clasp as in the main photo. Other photos showing the watch on other strap types are for presentation only. If you prefer a different type of strap, feel free to contact us for availability.”
