THE ROLEX GMT-MASTER II
THE PILOT’S WATCH

The GMT-Master, introduced in 1955, was developed to meet the needs of intercontinental airline pilots, and proved invaluable to those whose professions involve long-distance travel. Featuring a rotatable 24-hour graduated bezel and a separate 24-hour hand, it allows those who travel the world to read two different time zones simultaneously, and up to three by turning the rotatable bezel.
