Way back in 1954, the Rolex company, in collaboration with Pan Am Airways, designed and launched the Rolex GMT Master watch to be worn specifically by their pilots and crew during long-haul flights. GMT stands for Greenwich Mean Time, which is the time zone require for anything relevant to aviation, such as planning, weather forecasts, flight schedules, and some paperwork. The main features of the original version of the Rolex GMT Master includes the 24 hour display fourth hand complication, rotatable 24 hour scale bezel where it could be set to another time zone, which is beneficial for the crew to manage jet-lag and to communicate timely with their families back home whenever they were abroad. This watch became the official time pieces worn and used by pilots as well as astronauts because of its precision.
Sometime in the early 1980′s, the Rolex GMT Master II was introduced to the public. Although it looked very similar, almost identical, to the original version, it had added features and enhancements, such as a movement capable of being independently adjusted to a local time without disturbing or stopping the movement of the GMT hand. A lot of other watch designers and labels tried to copy or adopt the GMT 24 hour hand feature of the Rolex but no watch designer has ever succeeded and no watch has ever been so precise as the Rolex is.
In 2007, marking the Rolex’s 50th anniversary, the Rolex GMT Master II was updated with new technical features such as the patented Parachrom hairspring and the larger Triplock crown. Even the physical aspect of the Rolex GMT had undergone some changes like how the case is larger, with hands, markers, and the bezel made of a very hard ceramic that was guaranteed to be resistant to scratches and fading.
The original Rolex GMT Master was made of stainless steel because it was meant to be used at work. But as time passed by, Rolex started to make more luxurious versions that come in steel mixed with gold, gold, and some studded with precious stones.
