Quick TakeThe Sinn U18 isn't just a watch; it's a wearable artifact of naval prowess. Feel the heft of genuine submarine steel, once part of the U 18 vessel that traversed nearly 200,000 nautical miles. The dial doesn't just tell time; it portrays an undersea world with its deep blue-green gradient and air bubble accents. Every glance reminds you of the U18's legacy, with the nautical miles traveled and its type designation discreetly present. The TEGIMENT-hardened bezel can withstand daily wear and scratching, and the watch's impressive 200-bar water resistance shows it can handle underwater environments, just like the submarine. Beyond specs, this watch will tell the time and help connect you to history, engineering, and the depths of the ocean – all from your wrist. It is limited to 1000 pieces.

DescriptionThe Sinn U18, reference 1028.010, represents a convergence of historical significance and advanced horological engineering. Its construction integrates material directly sourced from the decommissioned German submarine U 18, specifically the high-strength, seawater-resistant steel from its outer hull. The steel's origins imbue the watch with a tangible connection to the submarine's impressive service record, which includes a logged 192,842 nautical miles – approximately nine circumnavigations of the Earth. This unique steel, originally developed by ThyssenKrupp for Type 206 and Type 212 submarines, underwent meticulous processing by Sächsische Uhrentechnologie GmbH Glashütte (SUG) to meet Sinn's exacting standards while retaining its historical essence. The watch, produced in a limited edition of 1,000 units, receives a satinized finished case.

The U18's 44mm case, with a thickness of 15.5mm and a lug width of 22mm, exhibits a robust presence. Weighing 114 grams without the strap, the case features a screw-fastened back and a screwable crown positioned at 4 o'clock. This positioning of the crown aims to eliminate any pressure on the wearer's hand. The bezel, manufactured from the same U 18 submarine steel, incorporates Sinn's TEGIMENT technology, providing enhanced scratch resistance. The bezel, with a minute ratcheting, uses the captive design. A double-sided anti-reflective sapphire crystal protects the dial. Beneath the crystal, a high-gloss dial portrays a bluish-green hue, representing the ocean's depths at around 30 meters. The dial design further incorporates stylized air bubbles for a three-dimensional visual experience. Internally, the U18 features the SW300-1 self-winding movement, operating at 28,800 semi-oscillations per hour, containing 25 bearing jewels, with a second-stop function. The movement fulfills the anti-magnetic specifications of DIN 8309. Functionality includes displaying the hours, minutes, seconds, and the date.
