1978 Rolex GMT-Master (Ref. 1675) "Pepsi" Mk V Dial

The Rolex GMT-Master, a symbol of sophistication and versatility, has a storied history that dates back to 1954. It all started when Rolex received a request from Pan American Airways (Pan Am) to develop a technical pilot's watch capable of displaying two time zones simultaneously. With the advent of commercial transcontinental flights, Pan Am needed a watch for their long-haul international flight crews that would enable them to keep track of time in multiple locations.

GMT, which stands for Greenwich Mean Time, is the universal time standard that regulates the world's clocks and serves as the basis for aviation planning and schedules. The Rolex GMT-Master is equipped with a fourth 24-hour hand that displays the same time zone as the standard 12-hour hand but on a 24-hour scale. This GMT hand allows wearers to set the watch to GMT or any other time zone and then adjust the offset using the rotating 24-hour bezel to display a second-time zone. This remarkable feature makes the Rolex GMT-Master a must-have for anyone who frequently travels across multiple time zones, allowing them to keep track of two time zones with ease and precision.
