Dual Time Icon Originally developed in collaboration with Pan Am in the 1950s, the Rolex GMT-Master II was designed for pilots and global travellers. Its hallmark is the ability to track multiple time zones simultaneously, aided by a 24-hour rotatable bezel and an additional GMT hand. The model has since become a symbol of cosmopolitan style and technical precision.
