Designer and watch fanatic Alejandro Alcocer advances his range of limited edition custom matte black Rolexes with the repurposing of a vintage GMT Master II. Alleged to have originally released in the 1960s exclusively for the Royal British Army, this updated wristwatch continues to awe even the most novice of watch collectors. 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. Alcocer only made 50 of these beauties and retailer SSENSE was lucky enough to get its hands on number 48. Pick it up here before someone else with $20,000 USD to spare beats you to it.
