Heritage Narrative
The Rolex GMT-Master II has been a symbol of global travel and precision since its introduction in 1982, evolving from the original GMT-Master first launched in 1955. Among its many executions, the “Batman” — distinguished by its black-and-blue Cerachrom bezel — has become one of the most coveted modern Rolex sport models. Introduced in 2013 and later updated with the calibre 3285 movement, it combines unmistakable style with Rolex’s latest technical innovations.
This September 2025 example, reference 126710BLNR, features a 40 mm Oystersteel case, black dial with Chromalight luminescence, and the iconic two-tone bezel insert in black and blue ceramic. Powered by the calibre 3285, it delivers a 70-hour power reserve, independent local hour setting, and Rolex’s Superlative Chronometer certification. Offered unworn and accompanied by its full set of box and papers, it represents a pristine iteration of one of Rolex’s most desirable travel watches.
