The Rolex GMT-Master II is one of the world's most recognisable professional watches, created for international travel and designed to display two time zones simultaneously. This highly sought-after reference 126710BLNR, commonly known amongst collectors as the "Batman" or "Batgirl" depending on bracelet configuration, is crafted entirely from Oystersteel and features the distinctive blue and black ceramic bezel that gives the reference its unmistakable appearance.
The 40mm Oyster case surrounds a classic black dial with Rolex's Chromalight display, providing excellent legibility in low-light conditions. Its defining feature is the bidirectional 24-hour graduated bezel with a two-colour blue and black Cerachrom ceramic insert, complemented by the blue arrow-tipped GMT hand. Together, these allow the wearer to simultaneously read local time and a second time zone.
Powering the watch is the Rolex Manufacture Calibre 3285, a self-winding mechanical GMT movement offering approximately 70 hours of power reserve. The independent rapid-setting hour hand makes changing local time particularly convenient when travelling, while the sapphire crystal with Cyclops date magnifier, Triplock screw-down crown and 100-metre water resistance provide the durability expected from a Rolex Professional model.
This example is supplied with its original Rolex box and papers dated 2023. Combining one of Rolex's most distinctive modern colour combinations with the practicality of the GMT complication, the 126710BLNR remains an exceptionally desirable modern Rolex sports watch and a versatile choice for both everyday wear and collecting.
