The GMT-Master II 126710BLNR — nicknamed “Batman” for its black-and-blue bezel — became one of the most coveted Rolex sport watches when it debuted on the Jubilee bracelet. Previous BLNR references rode the Oyster bracelet, but the switch to Jubilee gave this reference a distinctive wrist presence that collectors immediately embraced. The combination of tool-watch functionality and dressy bracelet architecture is what makes the 126710BLNR a crossover favourite.

The 126710BLNR Up Close: Case, Dial and Bracelet
The 40mm Oystersteel case houses a black lacquer dial with applied luminescent hour markers and a green GMT hand that reads against the 24-hour bezel markings. The bidirectional Cerachrom bezel insert transitions from black (night hours) to blue (day hours) at the eighteen-hour mark, offering a visual day-night reference alongside its functional purpose. The ceramic surface resists scratching and UV fading.
The five-piece link Jubilee bracelet gives the Batman a more refined drape compared to the three-piece Oyster, and it terminates in an Oysterclasp with Easylink micro-adjustment. Browse other bezel colour combinations in the GMT-Master collection.
