Rolex GMT-Master II 40 mm 126710BLROJ Steel Black

The Rolex GMT-Master II 126710BLROJ is the definitive modern expression of one of watchmaking's most storied pilot and traveler's watches. Introduced as part of Rolex's current-generation GMT-Master II collection, the reference 126710BLROJ carries forward nearly seven decades of GMT heritage—born from a 1950s partnership with Pan American World Airways—while delivering thoroughly contemporary engineering and materials. Its 40mm Oystersteel case strikes the ideal balance between presence and wearability, sitting comfortably on a wide range of wrist sizes without the bulk associated with larger sports watches.

The dial side of the 126710BLROJ is immediately arresting. The clean black lacquer dial is populated with luminous Chromalight-filled hour markers and hands that deliver exceptional legibility in low light. A distinctly red 24-hour hand—sometimes called the "GMT hand"—sweeps around the dial once every 24 hours, allowing the wearer to simultaneously track a second time zone against the graduated bezel. The date window at 3 o'clock, magnified by the signature Cyclops lens, rounds out a dial that is purposeful yet elegant.

The bezel is the defining design element of this reference. The bidirectional rotatable 24-hour graduated bezel is set with a two-color Cerachrom insert in black and red—a colorway that collectors and enthusiasts have nicknamed "Sprite" (following the "Pepsi" blue-and-red and "Batman" black-and-blue monikers). Cerachrom ceramic is virtually scratchproof, colorfast against UV exposure, and inert to most chemicals, meaning this bezel will look as vivid decades from now as it does today. The engraved numerals and graduations are filled with a PVD-deposited platinum coating for sharp, lasting contrast.

Perhaps the most distinctive aspect of the 126710BLROJ within the GMT-Master II family is its bracelet choice. While the companion 126710BLRO reference pairs the same Sprite bezel with an Oyster bracelet, the BLROJ designation denotes the five-link Jubilee bracelet—a more refined and supple option that offers exceptional wrist comfort and a dressier aesthetic. The Jubilee is secured by Rolex's Oysterlock safety clasp with Easylink 5mm comfort extension, allowing for quick on-the-fly length adjustment. This bracelet-bezel pairing has earned the 126710BLROJ a devoted following among collectors who want the sporty GMT complication dressed in something a touch more sophisticated.

Powering this watch is Rolex's automatic movement, offering the independently settable GMT hand that allows rapid time-zone changes without disturbing the running seconds—an essential feature for frequent travelers. The Oystersteel case and screw-down Triplock crown provide 100 meters (330 feet) of water resistance, and the scratch-resistant sapphire crystal with anti-reflective coating ensures the dial remains protected and perfectly visible under any lighting condition.
