Sinn U18 Limited Edition Watch

Limited Edition of 1000 Pieces. Sinn U18 Limited Edition 1028.010. 192,842 nautical miles in 38 years – a proud legacy. Commissioned in 1973, submarine U 18 achieved an impressive record: 192,842 nautical miles, meticulously documented by a former crew member. This astonishing figure equals about nine journeys around the globe! After its decommissioning, Sinn Spezialuhren acquired material from the submarine’s outer hull, using it to craft the heart of a unique, limited-edition diving watch. Limited to 1,000 pieces, the watch case is made from high-strength, seawater-resistant steel sourced directly from the U 18 submarine. This makes the submarine not only the namesake of model U18 but also an exclusive material source—and a timeless link to an unforgettable era in German submarine history.
