Quick TakeThe Sinn U15 isn't just a dive watch; it's a wearable piece of history. The very steel of its case once sailed the ocean depths as part of the U 15 submarine. This thing is TOUGH! You've got TEGIMENT-hardened submarine steel, a captive bezel that won't get knocked out of place, and 500 meters of water resistance, certified by an outside lab. The captivating dial, shimmering blue-green like the sea at 30 meters, draws you in, while the subtle nods to the U 15's impressive 200,045 nautical mile journey—represented by text and a Type 206 submarine engraving—add a layer of historical weight. And that SW300-1 movement? That classic, steady workhorse movement is made to last, much like the submariners it commemorates. This watch makes you feel you are ready for anything the ocean, or life, could throw at you.

DescriptionThe Sinn U15, reference 1025.010, represents a unique convergence of horological engineering and maritime history. Limited to 1,000 pieces, its 41mm case is constructed from high-strength, seawater-resistant German Submarine Steel. This isn't just any submarine steel; it's sourced directly from the decommissioned U 15 submarine, a vessel that logged 200,045 nautical miles during its service. The case itself is satinized, providing a muted, functional aesthetic. The screw-fastened case back is, engraved with a silhouette of the Type 206 submarine. The screwable crown, strategically positioned at 4 o'clock, is designed to prevent discomfort against the back of the hand during active use.

The diver's bezel, also fabricated from the same German Submarine Steel, features a satinized and polished finished and Sinn's TEGIMENT Technology, greatly increasing its scratch resistance. This captive bezel incorporates a minute ratcheting mechanism for precise timing of dives. The dial is protected by a sapphire crystal, treated with anti-reflective coating on both sides to ensure clarity under various lighting conditions. Powering the U15 is the SW300-1 self-winding movement, containing 25 bearing jewels, beating at a frequency of 28,800 semi-oscillations per hour, which has a second stop function and is Anti-magnetic as per DIN 8309. The U15 meets and excedes the requirements for water resistence from the DIN 8310 standard. The watch has undergone rigorous testing to meet European diving equipment standards (EN 250 / EN14143) and German diving norm DIN 8306, certified by an independent institute. It boasts a water resistance and pressure resistance of 500 meters (50 bar), also independently certified, and is low-pressure resistant. The watch displays hours, minutes, and seconds, along with a date display. The band lug width measures 20 mm, while the case thickness is 11.2 mm. The weight of the case, excluding any strap or bracelet, is 74 grams.
