With the diving watch U1, Sinn engineers succeeded in developing a diving watch in which the quality of material and design gives it superior resistance to external influences under extreme conditions of use.
In their search for a steel with the desired resistance, the Sinn engineers found what they were looking for at the German submarine manufacturer ThyssenKrupp Marine Systems: the steel manufacturers supply small quantities of the original steel of the current German submarine production exclusively to Sinn for making diving watches — the very steel of which the external hulls of the German Navy's new submarine class 212, which currently represents the most advanced non-nuclear submarines in the world, are made. This original submarine steel is not only extraordinarily seawater-resistant but is also of the highest non-magnetic quality without any residual magnetism.
To ensure reliably that the rotating bezel of the diving watch does not detach under harsh impacts, it is attached as a captive bezel to the central part of the case.
The water-resistance and pressure resistance of 100 bar (= 1000 m water depth) was certified for the diving watch U1 by DNV GL. The safety test pressure used for this purpose was 125 bar.

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.
