Rolex GMT-Master II 40 mm 126710GRNRJ Steel Black

The Rolex GMT-Master II reference 126710GRNRJ is one of the most celebrated and instantly recognizable watches in the current Rolex catalog. Introduced as a successor to the beloved two-tone "Root Beer" GMT-Master references of the quartz era, the 126710GRNRJ revived the warm black-and-brown color scheme in a thoroughly modern package when Rolex unveiled it at Baselworld 2018. For collectors and enthusiasts, its arrival marked a landmark moment: the first time Rolex had produced a brown-toned ceramic bezel insert, a technically demanding achievement in Cerachrom manufacturing that had long seemed unlikely.

The design of the 126710GRNRJ is immediately distinguished by its Cerachrom bezel insert in a gradient of black and brown — affectionately called "Root Beer" by the collector community, a nod to the original gold-and-steel GMT-Master references that carried similar tones in the 1980s. The bezel is bidirectional and graduated in 24-hour increments, allowing the wearer to simultaneously track a second time zone at a glance. Paired with a crisp matte black dial dressed with luminous Mercedes hands and applied hour markers, the watch achieves a balance of bold character and everyday legibility.

The 40mm case is crafted from Oystersteel, Rolex's proprietary 904L stainless steel alloy, which is renowned for its exceptional corrosion resistance and high-polish finish retention. The case profile follows Rolex's modern architecture with brushed and polished surfaces that catch the light on the wrist. With a water resistance rating of 100 meters (330 feet), this is a watch built to accompany an active lifestyle without compromise.

Powering the 126710GRNRJ is a Rolex-manufactured automatic movement, regulated to Superlative Chronometer standards — the brand's proprietary certification that guarantees precision performance within plus or minus two seconds per day, a standard that exceeds COSC requirements. The movement also drives a smooth-gliding GMT hand independently of the local-time hands, enabling intuitive dual-time-zone management that made the GMT-Master the first choice of international travelers and pilots since its debut in the 1950s.

One of the most distinctive features of the 126710GRNRJ is its bracelet: Rolex chose the elegant five-piece Jubilee bracelet rather than the Oyster bracelet typically associated with tool watches, and this pairing has become a hallmark of the reference. The Jubilee wears with a supple, dressy quality that distinguishes this GMT from its sport-oriented sibling references, and it is fitted with Rolex's Easylink comfort extension system for on-the-fly sizing adjustments.
