This original submarine steel is not only extraordinarily seawater-resistant but is also of the highest non-magnetic quality without any residual magnetism.\u003cbr\u003e\u003cbr\u003eTo ensure reliably that the rotating bezel of the diving watch does not detach under harsh impacts, it is attached as a captive bezel to the central part of the case.\u003cbr\u003e\u003cbr\u003eThe water-resistance and pressure resistance of 100 bar (= 1000 m water depth) was certified for the diving watch U1 by DNV GL. The safety test pressure used for this purpose was 125 bar.\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003e\u003cstrong\u003eKey features:\u003c\/strong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e    Case and crown made of high-strength, seawater-resistant German Submarine Steel\u003c\/li\u003e\n\u003cli\u003e    Bezel with TEGIMENT Technology and therefore especially scratch-resistant\u003c\/li\u003e\n\u003cli\u003e    Diameter of case: 44 mm\u003c\/li\u003e\n\u003cli\u003e    Tested based on European diving equipment standards and certified by DNV GL\u003c\/li\u003e\n\u003cli\u003e    Captive diver's bezel with minute ratcheting\u003c\/li\u003e\n\u003cli\u003e    Crown at 4 o'clock to prevent pressure on the back of the hand\u003c\/li\u003e\n\u003cli\u003e    Sapphire crystal glass\u003c\/li\u003e\n\u003cli\u003e    Waterproof and pressure-resistant to 1,000 m diving depth (= 100 bar), certified by DNV GL\u003c\/li\u003e\n\u003cli\u003e    Low pressure resistant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"Sinn","offers":[{"title":"Default Title","offer_id":52586283663626,"sku":"1010.010-BLK-RUBBER","price":2515.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0926\/5276\/5450\/files\/sinn-mens-u1-german-submarine-steel-divers-watch-p35266-53016_image.jpg?v=1781646258","url":"https:\/\/www.francisandgaye.co.uk\/products\/sinn-mens-u1-german-submarine-steel-divers-watch-1010-010-blk-rubber","provider":"Francis \u0026 Gaye","version":"1.0","type":"link"}
