The Rolex GMT-Master II 126710GRNR — quickly nicknamed the "Bruce Wayne" by collectors for its dark, restrained aesthetic — is the gray-and-black Cerachrom bezel GMT-Master II that arrived in the Rolex lineup in 2024. Among Rolex's growing portfolio of two-color ceramic bezels, the GRNR carries a uniquely monochromatic palette: graphite gray on the daylight 6-to-18-hour half of the 24-hour scale, jet black on the nighttime 18-to-6 half, with no contrasting color accent on the bezel itself. The result is a stealthier visual identity than the Pepsi, Batman, or Sprite bezel options that preceded it. Housed in a 40mm Oystersteel Oyster case on the matching Oyster bracelet with the Oysterlock safety clasp and Easylink 5mm comfort extension, the 126710GRNR is fitted with the bidirectional rotating bi-color Cerachrom ceramic bezel and a glossy lacquered black dial with applied 18k white gold hour markers, Mercedes hands with Chromalight luminescence, and the central 24-hour GMT hand in green — the one shot of color that breaks the monochrome. Powered by the in-house Rolex Caliber 3285 automatic movement with the patented Chronergy escapement, paramagnetic Parachrom hairspring, and 70-hour power reserve, the 126710GRNR carries Superlative Chronometer certification. Screw-down Triplock crown, 100 meters water resistance. Pre-owned.
