Rolex originally produced the GMT-Master in 1954 as an aviation watch for pilots, inspired by Pan Am’s request for a timepiece that could display multiple time zones simultaneously. Ever since it has been a popular watch among frequent travelers and international businesspeople. Like many Rolex watch models, the GMT-Master II 126710BLNR Blue/Black is known by its fun nickname, the Batman—a reference to its elegant color scheme. The Rolex GMT-Master II Batman 126710BLNR most impressive feature is undoubtedly this dual time zone function, which has been designed with easy legibility in mind using a combination of the sleek black dial and the bidirectional, rotatable black and blue bezel.

The local time is displayed on the watch face using Rolex’s iconic geometric hour markers, but an extra hand, distinguished by its blue cool and arrow tip, indicates the reference time, shown on the scratch-proof aluminum and Cerachrom bezel using the 24-hour system. Both times can be set independently using the Triplock winding crown and both the hour markers and hands are made with photoluminescent Chromalight, which glows blue in low light, making the Rolex GMT-Master IIBatman 126710BLNR highly readable in all conditions. 

The GMT-Master II Batman 126710BLNR stands out from other Rolex GMT-Master II models because it is fitted with the sporty Oyster bracelet combined with an Oysterlock folding clasp with a safety bar to prevent accidental opening and Rolex’s Easylink extension function. The bracelet, clasp, and case are made from non-corrosive Oystersteel. The Rolex GMT-Master II Batman 126710BLNR new caliber 3285 movement boasts an incredible 70-hour power reserve and a Blue Parachrom hairspring that has outstanding resistance to heat, shocks, and magnetic fields, making it a timepiece to last a lifetime.
