The Supermarine Full Ceramic Deep Blue is a 250-piece limited edition and the latest chapter in Bremont's Supermarine Full Ceramic line. Inspired by the meeting point of ocean and ice, this blue dive watch rubber strap model is built for the world's harshest environments. The 43mm mono-block blue ceramic case is highly scratch-resistant and exceptionally lightweight, with a titanium inner case, a helium escape valve and 500 metres of water resistance. A knurled titanium uni-directional bezel holds a blue ceramic insert. On the black wave-effect dial, trapezoid indexes flow from the bezel to form a naval-inspired crosshair, filled with Super-LumiNova® (blue emission). The date sits at 3 o'clock, and the titanium case back is engraved with a map of the world's oceans. Powered by the automatic BB64AH movement with a 56-hour power reserve, the Deep Blue was tested by Bremont Ambassador Aldo Kane in Iceland: in the freezing water of glacial lakes and across the country's glaciers. Presented on a black rubber chevron strap. Super-LumiNova® Indexes and hands are filled with Super-LumiNova® (blue emission) for clear legibility in the deep.
