Released in 1954, the GMT-Master resulted from Pan Am and Rolex collaborating on a watch that could tell the time in two different places at once
With the further innovation and popularisation of commercial flying, the distances of flights became greater. This resulted in pilots crossing into different time zones more frequently. Thus, a need for uniformity across the industry was borne as potential issues could arise when communicating with ground teams in a different time zone to the pilots. To eliminate these errors, the aviation industry adopted a standard time-zone, Greenwich Mean Time. As such, the GMT-Master’s fourth hand, the 2nd-hour hand, was to stay on Greenwich Mean Time – which is where the name for the watch comes from.
