Quick TakeThe U1 S isn't just a dive watch; it's a testament to resilience, molded from German Submarine Steel. With its stark, matte black dial and bold, luminescent markers, it whispers of deep-sea adventures, while the satisfying click of its captive, minute-ratcheting bezel speaks to the precision within. Don't just picture a tool on your wrist. The U1 S has a soul, powered by the steadfast SW 200-1 movement, ticking away at 28,800 beats per hour. It is ready for anything. Feel that substantial 113-gram presence, knowing it can handle the crushing pressure at 1,000 meters, just as easily as it can handle your daily grind. This is a companion that is built, certified, and prepared, to face depths others only dream of.

DescriptionThe Sinn U1 S, reference number 1010.020, represents a significant evolution in dive watch construction, distinguished primarily by its use of high-strength, seawater-resistant German Submarine Steel for both the case and crown. This specialized steel provides not only superior corrosion resistance against saltwater environments but also offers exceptional non-magnetic qualities, adhering to DIN 8309 anti-magnetic standards. A Black Hard Coating, applied using TEGIMENT Technology, enhances the case's durability, contributing to its robustness and scratch resistance. The watch's case diameter measures 44mm, with a band lug width of 22mm and a case thickness of 14.7mm. The weight, without the strap attached, is documented at 113 grams. The screw-fastened case back and screwable crown are engineered to meet the technical prerequisites for water resistance as delineated in standard DIN 8310.

Powering the U1 S is the SW 200-1 self-winding mechanical movement. This movement incorporates 26 bearing jewels and operates at a frequency of 28,800 semi-oscillations per hour. A seconds stop function is integrated for precise time setting. A matte black dial provides a backdrop for indices and hands, all treated with luminescent coating to guarantee visibility in low-light conditions. The date display is positioned discreetly, balancing functionality with visual clarity. Further features include the sapphire crystal with anti-reflective coating on both sides. The U1 S displays hours, minutes, and seconds. It incorporates a diver’s bezel, engineered with minute ratcheting, and a luminous key mark. The diver's bezel employs a captive design, specifically engineered to avoid detachment under duress. This timepiece has undergone rigorous testing, conforming to European diving equipment standards EN 250 and EN14143, and exceeding the German diving norm DIN 8306, certified by an independent institute. It features resistance to water pressure up to a depth of 1,000 meters (100 bar) and maintains functionality in low-pressure situations.
