Sinn Sinn U50 on Silicone Strap 1050.010 S
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 GL. DNV GL 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.

Additional Product Details
Sinn Watches was formed in 1961 by the legendary pilot and flight instructor Helmut Sinn. They began manufacturing flight watches based on his extensive aviation experience, this was primarily based on Mr. Sinn's dissatisfaction with the watches that were available for pilot and navigational purposes at that time. His own designs incorporated the features and functionality that he felt more fit for purpose as an instrument watch. This is a design philosophy that has transcended the company's culture right through to the present day. Sinn is now the world's most eminent manufacturer of high quality, precision, functional and purposeful instrument watches. From the beginning, their emphasis was on creating special purpose instruments that performed under extremely adverse operating conditions such as high speed, high and low pressures and altitudes, intense heat or pressure, extreme cold, high magnetic interference, and submergence in liquids. Sinn are becoming increasingly known for their instrument watches, and are today a force to be reckoned with as they lead the way in instrument watch design. The company changed hands in 1994 when Lothar Schmidt formerly of IWC assumed control and further expanded the boundaries of Sinn’s high tolerance manufacturing expertise. Over the past decade, Sinn has pioneered some innovative new technologies, including oil filled watch chambers to enable operation under extreme pressures, argon gas filled watches to prevent moisture infiltration, impact resistant gear suspensions, and new micro-lubricating techniques. Their timepieces are standard equipment in some of the most dangerous and adverse environments on earth - little surprise their watches are issued to the German military and elite forces. Above all the watches are manufactured and marketed to the world at large. Like the designs and their application areas, the pricing of the Sinn watches is most aggressive, making them available to most people. Due to distribution agreements Sinn watches can only be shipped to the UK and Ireland and certain countries where there is no Sinn agent assigned to that territory. Sinn watches are covered by a two or three year manufacturers warranty depending on the model.
