Tropical 1990 Rolex GMT-Master II (Ref. 16710)


The Rolex GMT is the jet-setting icon of the Rolex sports watch family. The history of this sophisticated, versatile style dates back to 1954 when Rolex received a request from Pan Am to create a technical pilots watch that could indicate two time zones simultaneously.   As advances in aviation made transcontinental flights commercially available Pan Am needed a watch that could be issued to their crews on long-haul international flights.

GMT stands for Greenwich Mean Time - the time zone that regulates world clocks and is required for all aviation planning and schedules. The Rolex GMT Master has a fourth 24-hour hand that directly displays the same time zone as the standard 12-hour hand but on a 24-hour scale. The addition of this GMT hand enabled crews to set the watch to GMT or another time zone, and, using the rotating 24-hour scale bezel, correct the offset to display a second time zone on the 24-hour scale. This feature is just as useful today, allowing the modern traveler to easily keep track of his home time zone, no matter how far he may have journeyed.

This modern classic is absolutely stunning which has achieved a very interesting and sought after patina. This specific example would make a great stand-alone piece or a great addition to an existing collection!

The thick case has been lightly polished in the past and shows light wear from use. The red half of the "Pepsi" bezel insert has faded to a wonderful pink coloration. The watch was sourced with a Rolex 93150 Oyster bracelet with 593 end pieces than remains in great overall condition displaying honest wear and light stretch from use.


The originally black glossy dial has taken on a gorgeous tropical brown patina that is consistent throughout the dial. The tritium lume plots have aged to a lovely yellow coloration, under U.V. light inspection the 9 and 12 o'clock markers show some very minor degradation that is not visible with the naked eye. The original hands match the dial and don't show any lume degradation.


None. The watch is keeping time within COSC spec and was last serviced in 2018
