Rolex - GMT-Master II - 126710BLNR - 2024

The Rolex GMT-Master II traces its origins to the original GMT-Master of 1955, developed in collaboration with Pan American World Airways for pilots navigating multiple time zones. The 126710BLNR, known among collectors as the “Batman” for its blue and black Cerachrom bezel, represents the modern evolution of Rolex’s most recognisable travel watch, combining professional functionality with contemporary engineering.

The 40mm Oystersteel case provides the strong yet balanced presence expected of the GMT-Master II line. Its bidirectional rotating bezel is fitted with a monobloc Cerachrom insert in blue and black ceramic, with 24-hour graduations moulded into the surface and coated with platinum for lasting definition. A sapphire crystal with Cyclops lens protects the dial, while the Oyster case construction provides 100 metres of water resistance.

The black dial is clean, purposeful and highly legible, carrying applied Chromalight hour markers and matching hands for excellent visibility in low light. The date aperture sits at three o’clock beneath Rolex’s signature Cyclops lens, while the independent GMT hand, tipped with a green triangle, works against the rotating bezel to display a second time zone.

Powering the watch is Rolex’s Calibre 3285, a self-winding GMT movement developed and manufactured entirely in house. It features Rolex’s Chronergy escapement, a blue Parachrom hairspring and Superlative Chronometer certification, delivering exceptional precision, resistance and reliability. With approximately 70 hours of power reserve, the movement offers the performance expected from Rolex’s latest generation of professional calibres.

The Oystersteel Oyster bracelet gives the watch a robust and practical character, with its three-piece link construction offering strength, comfort and everyday versatility. Secured by an Oysterlock safety clasp and fitted with Rolex’s Easylink 5mm comfort extension, it provides both security and fine adjustment on the wrist.

Very good condition from 2024 reflects careful modern ownership, with signs of wear consistent with regular use. Expect moderate surface marks to polished areas, light dulling to brushed components and possible desk-diving marks to the clasp, with no significant damage to the watch’s functionality or integrity. Supplied complete with its original box and original papers. The five-year manufacturer’s warranty remains active until 2029.

A modern benchmark for the travelling professional, the GMT-Master II 126710BLNR combines dual time zone functionality, ceramic bezel technology and Rolex’s latest generation movement architecture. Distinctive, capable and instantly recognisable, it stands as one of the most desirable contemporary sports watches in the Rolex catalogue.
