The Rolex GMT-Master is a legendary pilot’s watch designed for tracking multiple time zones simultaneously. Originally created in the 1950s in collaboration with Pan American Airways for their pilots, it features a distinctive 24-hour rotatable bezel and an additional GMT hand to display a second time zone. Known for its colorful bezel options—like the iconic red and blue "Pepsi"—the GMT-Master blends practicality with bold style. It’s favored by travelers and professionals who need to keep track of time across different regions, combining durability, precision, and a strong heritage.
