Sinn U50 B on Steel Bracelet
3 WEEK DELIVERY
The U50 B is a precision instrument for divers and at the same time a bold statement in design. The striking matt-blue dial immediately draws the eye, signalling the highest level of professionalism and underlining the uncompromising functionality of this watch – not least thanks to the white, luminous indices and hands, which provide a perfect contrast. The result: a harmonious overall appearance with outstanding readability.
In true SINN tradition, the U50 B combines well-conceived design with technical excellence: the case and crown are made of high-strength, seawater-resistant submarine steel with the highest non-magnetic quality – a material otherwise reserved for extreme maritime applications. The captive diver’s bezel proves to be especially scratch-resistant, as it has been further hardened with TEGIMENT Technology. A practical detail: the crown is positioned at 4 o’clock to prevent pressure on the back of the hand.
Whether for ambitious dives or as a reliable companion in everyday life, the U50 B excels in every respect, as confirmed by independent testing. Its suitability for underwater use has been verified and certified by an independent institute.
Please note, some images show the watch on blue silicone strap. This is for illustration purposes and not included with the steel bracelet model, but is available to order separately

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.
