GMT-Master II "Batgirl" Jubilee 40mm | Ref. 126710BLNR | 2025 Mint Full Set

The Story

The Rolex GMT-Master II holds an unshakeable position in horological history, originally developed in 1954 alongside Pan American Airways to meet the rapid needs of international pilots entering the jet age. Among modern references, the Ref. 126710BLNR, universally dubbed the "Batgirl" due to its blue-and-black colorway executed on the supple 5-link Jubilee bracelet, stands as the definitive modern expression of travel luxury. It discards utilitarian tool-watch minimalism to deliver a highly refined, instantly recognizable statement piece tailored for the collector who demands jet-set versatility and bulletproof Swiss mechanical pedigree.

The Craft: Cerachrom Metallurgy & The Calibre 3285 Engine

The 40mm case is sculpted from Rolex's proprietary Oystersteel (904L alloy), offering extreme corrosion resistance and brilliant polished facets along the case flanks and lugs. The bidirectional 24-hour rotating bezel features a patented two-tone blue and black Cerachrom ceramic insert, with platinum-coated numbers and graduations recessed into the scratch-resistant surface.

The black dial provides high-contrast legibility, decorated with applied 18K white gold hour indices and hands filled with long-lasting Chromalight blue luminescence. The signature royal blue GMT hand points to the 24-hour bezel scale, allowing instantaneous reading of a second time zone alongside local time.

Beneath the solid screw-down caseback beats the new-generation Manufacture Rolex Calibre 3285. Featuring the patented high-efficiency Chronergy escapement and blue Parachrom hairspring, this movement provides superior shock resistance and magnetic immunity. It offers an extended 70-hour power reserve and an independent jumping local hour hand for swift time-zone adjustment. Certified as a Superlative Chronometer (-2/+2 seconds per day accuracy after casing), the watch offers a professional water resistance rating of 100 meters (330 feet).
