Overview
The Rolex GMT-Master II reference 126710BLNR carries forward the beloved black-and-blue "Batman" bezel combination in a 40 mm Oystersteel case, pairing it with a crisp black dial. Introduced in 2019, it represents a significant technical step forward for the GMT-Master II line, housing the in-house Calibre 3285 for the first time in this configuration. The result is a sports-tool watch that balances decades of horological heritage with Rolex's most current movement engineering.
History
The GMT-Master lineage stretches back to the 1950s, when Rolex developed the original reference in collaboration with a major international airline to meet the needs of long-haul aviators and navigators tracking multiple time zones simultaneously. The black-and-blue bezel variant earned the "Batman" nickname among collectors when it debuted on the preceding reference 116710BLNR in the early 2010s, quickly becoming one of the most sought-after configurations in the modern GMT-Master II catalogue. The 126710BLNR succeeded that reference in 2019, retaining the distinctive two-tone Cerachrom bezel insert while introducing the Calibre 3285, a movement featuring a Chronergy escapement and a power reserve of approximately 70 hours. Its arrival cemented the "Batman" as a cornerstone of Rolex's contemporary sports-watch offering.
Notable points
- The Cerachrom bezel insert combines black and blue ceramic in a single piece, offering high resistance to scratching, fading, and corrosion.
- Calibre 3285 introduced the Chronergy escapement to this reference, improving energy efficiency and reliability over its predecessor movement.
- The independently settable 24-hour GMT hand allows a second time zone to be tracked without disrupting the local-time display.
- The 40 mm Oystersteel case is fitted with Rolex's Oyster bracelet and the Oysterlock safety clasp, maintaining the tool-watch ethos of the line.
- The black dial and matching black-and-blue bezel create a cohesive, high-contrast aesthetic that distinguishes the 126710BLNR from the red-and-blue "Pepsi" and root-beer variants in the GMT-Master II family.
