The Rolex GMT is the jet-setting icon of the Rolex sports watch family. The history of this sophisticated, versatile style dates back to 1954 when Rolex received a request from Pan Am to create a technical pilot watch that could indicate two time zones simultaneously. As advances in aviation made transcontinental flights commercially available Pan Am needed a watch that could be issued to their crews on long-haul international flights.
GMT stands for Greenwich Mean Time - the time zone that regulates world clocks and is required for all aviation planning and schedules. The Rolex GMT Master has a fourth 24-hour hand that directly displays the same time zone as the standard 12-hour hand but on a 24-hour scale. The addition of this GMT hand enabled crews to set the watch to GMT or another time zone, and, using the rotating 24-hour scale bezel, correct the offset to display a second-time zone on the 24-hour scale. This feature is just as useful today, allowing the modern traveler to easily keep track of his home time zone, no matter how far he may have journeyed.
The Rolex Ref. 16750 was first introduced in 1979 and was in production until 1988. The main difference between the Rolex GMT ref Ref. 1675 and the 16750 was the introduction of the Cal. 3075 movement which allowed for instantaneous date advancement also known as "quick set". The 16750 GMT-Master is perfect for on the go daily wear, but is also very versatile in a collection as it is only a simple step to change the date!
