More information
The Rolex GMT Master was developed in cooperation with Pan Am, which asked Rolex in the to develop a watch which could tell different times simultaneously.
The newly introduced fourth hand allowed the display of an additional time, with the corresponding numbermarkings on the outer bezel. Pilots used the second time to display the Greenwich Mean Time (GMT), which led to the name Rolex GMT-Master.
