Pre-owned Rolex GMT-Master II ref. 126710BLNR (2020). The modern “Batman” traces its roots back to 2013, when Rolex introduced the ref. 116710BLNR and unveiled the world’s first two-tone Cerachrom bezel. The distinctive black-and-blue color scheme immediately made it special and quickly earned the watch its comic book-inspired nickname. When Rolex released the next-generation ref. 126710BLNR in 2019, it retained the beloved bezel while introducing several notable updates. Among them was the return of the Jubilee bracelet, a configuration many collectors associate with vintage GMT-Masters. The pairing of the sporty black-and-blue bezel and the dressier five-link bracelet led enthusiasts to coin another nickname: the “Batgirl.” Beyond its collector appeal, the watch is still a highly capable travel companion, featuring a dedicated GMT hand and 24-hour bezel for tracking a second time zone.
