Watch enthusiast Alejandro Alcocer has extended his limited edition custom matte black Rolexes with this rendition of a vintage GMT Master II. Supposably originally released in the 1960s exclusively for the Royal British Army, the made in Switzerland GMT Master II features a 904L stainless steel base with Physical Vapor Deposition (PVD) matte black carbon coating, a Swiss Official Chronometer Testing Institute (COSC)-certified chronometer, a high-contrast display with luminous markers and a bidirectional rotating 24-hour graduated bezel. Further details include a layer of Diamond-Like Coating (DLC) for added strength, an oyster-styled bracelet with flat three-piece links, a Swiss automatic (self-winding) movement and acrylic crystal.
