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. The safety test pressure used for this purpose was 125 bar.\u003c\/p\u003e","brand":"Sinn","offers":[{"title":"Default Title","offer_id":52590611005706,"sku":"1010.040-BLK-RUBBER","price":2605.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0926\/5276\/5450\/files\/sinn-mens-u1-sdr-submarine-steel-diving-watch-p45068-87592_image.jpg?v=1781651053","url":"https:\/\/www.francisandgaye.co.uk\/products\/sinn-mens-u1-sdr-submarine-steel-diving-watch-1010-040-blk-rubber","provider":"Francis \u0026 Gaye","version":"1.0","type":"link"}
