Sinn U50 Hydro S – Tegimented Technology
Delivery end of April. Please email or call to reserve
When impressive functionality, perfect readability and technological innovation come together, the result is versatile and robust timepiece such as the U50 HYDRO S with its case and bezel with black hard coating on a tegimented base – realised in a comfortably wearable size of 41 mm diameter!
One of the outstanding features of the U50 HYDRO S is concealed inside the diving watch, meaning that its incredible effect becomes most evident under water: HYDRO Technology. The benefits never fail to impress experienced users: reflection-free underwater readability from any angle, absolute freedom from fogging and – thanks to the special oil filling – water-resistant and pressure-resistant up to a diving depth of 5,000 m (=500 bar).
The watch focusses on a striking design with a display that concentrates on the essentials. It owes its outstanding suitability for everyday use to high-quality features with special materials, which ensure that the U50 HYDRO can withstand even the most adverse conditions. The case and crown are thus made of high-strength seawater-resistant German Submarine Steel. It is characterised by its extreme strength and exceptional non-magnetic properties. Another advantage that stands out for connoisseurs is its outstanding resistance to seawater. The black hard coating on the case, crown and rotating bezel also puts an end to a disadvantage of conventional colour coatings: It does not flake off! The prerequisite for this is our TEGIMENT technology, a special hardening of the submarine steel that prevents the coating from flaking off due to different material hardnesses.
The positioning of the crown at 4 o’clock also deserves special attention. This prevents pressure on the back of the hand – even during physically demanding activities.
Due to the aforementioned oil filling, this timepiece must be a quartz watch, as the oscillation of the balance in a mechanical watch would be unable to overcome the high friction resistance of a liquid medium. Nevertheless, watch lovers needn’t forgo the reliability typical of SINN – the long-lasting lithium battery used ensures reliable function at temperatures ranging from –20°C to +60°C. The battery also has an exceptionally long service life. The movement’s integrated EOL (end of life) function prevents the watch from stopping suddenly.
Whether for professional use or to cope with the demands of diving, the U50 HYDRO S is perfect for such challenges – as has also been confirmed by independent classification company DNV. On our behalf, it tests and certifies pressure resistance to a diving depth of 5000 m (= 500 bar) and temperature resistance and functionality in accordance with the European diving device standards.

Key Characteristics
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.
