The birth of the GMT-Master began at the request of Pan American Airlines (Pan Am), A major U.S. airline. Pilots on long-distance flights needed a watch that could check multiple time zones simultaneously. As a result of their request for the ability to display two or more time zones, Including GMT (Greenwich Mean Time, Currently UTC), The standard time for international air travel, Rolex developed the GMT-Master Ref. 6542 in 1954 and officially launched it in 1955. This model featured a fourth hand (24-hour hand) that moved in 24-hour increments and a rotating 24-hour bezel, Setting a new standard for aviation watches.
Based on this history, The GMT-Master II (Ref. 116710LN) is considered a turning point for the Rolex Professional line. Produced from 2007 to 2019, This model is the successor to Ref. 16710 and was the first to introduce a ceramic bezel (Cerachrom) to a stainless steel model by Rolex. In addition, It set the standard for the steel Professional models that would be released later by applying a 40 mm Super case and a maxi dial. In particular, The Cerachrom bezel significantly improved the durability of the aluminum bezel, Improving discoloration and scratches. The green GMT-Master II logo and 24-hour hand are elements that show the brand’s meticulous attention to detail, And this design has continued to be reflected in subsequent models.
The movement has been upgraded to Cal. 3186, And the blue Parachrom hairspring has enhanced anti-magnetic and shock resistance. The bracelet has also evolved into a solid form, And the Easylink function has been added to simultaneously improve comfort and convenience. Ref. 116710LN, The only model to be released with a single-color ceramic bezel to date, Has seen its value skyrocket since production ended, Establishing itself as an iconic Rolex watch that connects the past and present.
