Tudor Pelagos

Tudor's Pelagos M25600TN-0001, a dive watch known as the LHD, has a 42 mm titanium case measuring 14.3 mm thick. The unidirectional rotating bezel is finished in titanium with a black graduated scale. A black dial carries luminous indices and hands along with a date window and central seconds, set under a sapphire crystal. Inside is the manufacture calibre MT5612, a self-winding chronometer movement with a 70-hour power reserve. A helium valve sits in the case, useful for saturation diving. The watch comes on a rubber strap, though Tudor also supplies a titanium bracelet with steel folding clasp. Waterproofness reaches 500 metres, a figure the helium valve and bezel are built to support.
