The Rolex GMT-Master originated in the age of transcontinental flights.
During the 1950’s, airplanes began crossing several time zones within a short period of time. As a result, the need for a watch that enabled its wearer to keep an eye on concurrent time zones arose. Back then, it was the pilots who primarily needed to know the time for both departure and destination airports. Thus, Rolex launched the GMT-Master (Ref. 6542) in 1954, and from day one, it was the official wristwatch on board Pan Am flights. Some experts claim that the characteristic red and blue bezel was inspired by the colours of the legendary airline. For most, however, the colours of the so-called Pepsi-bezel represent the difference between day and night.
The GMT-Master has been a great success since the very beginning. To this day, the striking wristwatch enjoys great popularity not only among pilots, but among worldwide watch enthusiasts, business travellers, and collectors.
