The Rolex GMT-Master II 'Root Beer' (Ref. 126710BLRO) features a distinctive two-tone ceramic bezel—black on the top half and brown (often called 'root beer') on the bottom—with white numerals, paired with a matching brown dial and green 24-hour hand. Crafted from Oystersteel (904L stainless steel), it houses the Calibre 3285 automatic movement with Chronergy escapement, offering ±2 sec/day precision and 70-hour power reserve. The bidirectional rotating bezel enables tracking of a second time zone, while the Chromalight luminescence ensures readability in darkness. Its robust Oyster Perpetual case (40mm) is waterproof to 100m, and the Jubilee bracelet offers a seamless, integrated fit. This iconic travel watch blends rugged functionality with refined luxury, making it ideal for frequent flyers, collectors, and discerning professionals seeking both performance and prestige. The green/black bezel variant is highly sought after for its bold contrast and vintage-inspired aesthetic, echoing the original 1950s GMT models while benefiting from modern Rolex engineering.
