When absolute readability becomes the priority, the U1 S L demonstrates what is technically possible.
Limited to just 300 pieces, this exceptional diving watch combines maximum functionality with innovative luminosity – even in complete darkness.
The highlight: the entire dial and the main marker on the rotating bezel glow intensely. In terms of its production, an innovative method is used to incorporate the luminous paint into a mould using a special casting process. After hardening, a hybrid ceramic component is created, which is joined to the metallic base dial. In the final processing step, the two combined components are printed. The result is rather remarkable – thanks to the high concentration and large surface area of the luminous paint, we achieve extreme luminosity and thus perfect readability – in a quality never seen before!
The U1 S L also makes a powerful visual statement: with its distinctive design language and clearly reduced display, it can be worn at any time – even outside the water.
Behind the striking appearance lies pure SINN technology: case and crown are made of high-strength, non-magnetic submarine steel, renowned for its exceptional seawater resistance. The high-quality Black Hard Coating, based on TEGIMENT Technology, provides a stylish look. And because reliability at SINN knows no compromise, the bezel is non-detachable and securely captive into the case.
Tested? Of course. An independent testing institute has certified the pressure resistance to a diving depth of 1,000 m (= 100 bar), as well as temperature resistance and functionality based on European diving equipment standards. The U1 S L is therefore a watch with real depth. In every respect.

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.
