Rolex GMT Master "Batgirl" 126710BLNR

Nickname culture is undefeated: give Rolex a two-tone bezel and collectors will name it faster than the brand ever will. Say hello to the "Batgirl," this 2026 Rolex GMT-Master II reference 126710BLNR, a 40mm stainless steel pilot's watch that trades the Oyster for the Jubilee and wears all the better for it. The same black-and-blue Cerachrom bezel that made the "Batman" a modern legend, here softened into something that slips under a cuff as easily as it clears a boarding gate.

The proportions Rolex has long treated as the GMT-Master's natural resting state, substantial enough to read as a tool watch yet trim enough to disappear under a shirt. What sets the "Batgirl" apart is the five-link Jubilee bracelet, finished with a concealed Crownclasp and an Easylink extension for on-the-fly comfort adjustment. The star of the exterior is the two-tone Cerachrom bezel, machined in scratch-proof ceramic with its 24-hour scale split blue for day and black for night, the detail that drives the whole GMT premise.

The dial is black lacquer with applied white gold markers and hands filled with Chromalight for a legibility that holds up long after dusk. A blue arrow-tipped GMT hand sweeps once every 24 hours to track a second time zone, while the date sits magnified beneath the Cyclops at three o'clock.

Inside runs the in-house automatic Caliber 3285, the movement that brought the GMT-Master II up to roughly 70 hours of power reserve and carries Rolex's Superlative Chronometer certification. It is the sort of caliber built to be set once and trusted across time zones, which is precisely the point of the watch.

This Rolex GMT-Master II remains in pre-owned condition. The seller reports no specific flaws. No service history has been disclosed.
