Introduction
Released in 1954, the Rolex GMT-Master resulted from a collaboration between now-extinct airline Pan Am and Rolex on a watch that would display the time across two time zones at once. Thanks to the popularisation of commercial air travel, planes were becoming more advanced and traveling longer distances. This resulted in pilots crossing time zones during flights more frequently, and thus a need for uniformity across the aviation industry was highlighted. To eliminate errors caused by time confusion, the industry adopted a standard time-zone, Greenwich Mean Time. As such, the GMT-Master's fourth hand, its 2nd hour hand, was used to constantly display Greenwich Mean Time, as its model name implies, while its regular hour hand displayed local time. While the aviation industry's standard time-zone switched to Coordinated Universal Time (UTC) in 1972, the name of the legendary GMT-Master was far too long in use for Rolex to change it. Today, the GMT-Master has become one of Rolex's most iconic models, with very few pilot's watches, if any, rivaling its level of fame, popularity, or signature design – and it certainly looks like it will stay that way.
Released in 2019 as a follow-up to the 'BATMAN' and thus nicknamed the 'Batgirl,' the ref. 126710BLNR features the newest cal. 3285 movement, paired with a jubilee bracelet and the Batman's signature blue and black Cerachrom bezel.

THE BEZEL
As its nickname suggests, this ref. 126710BLNR features a two-toned Cerachrom bezel, rendered in blue and black. The indexes are inlayed with platinum for maximum durability, and its black dial features a blue GMT hand which ties the display and the bezel together nicely.

THE BRACELET
The first sports watch from Rolex to feature a jubilee bracelet in a generation, the Batgirl adds a bit of flair to the usual sport Rolex on an oyster bracelet theme.
