1991 Rolex GMT-Master II (Ref. 16710) "Coke"

The Rolex GMT is the jet-setting icon of the Rolex sports watch family. Like the Rolex Submariner, the Rolex GMT is sophisticated, rugged, and versatile. In 1954 Pan Am started using the newly designed Boeing 707 which allowed for Pan Am to fly transcontinentally and is said to have started the commercially available jet age. In the same year, Rolex received a request from Pan Am to create a technical pilot's watch which indicated two time zones simultaneously that could be issued by the airline to their crews on long-haul transcontinental international flights. 

Rolex GMT Pan Am 1675

GMT or UTC stands for Greenwich Mean Time or Coordinated Universal Time which is the primary time standard by which the world regulates clocks and time. GMT or UTC is the time zone that is required for all aviation planning, weather forecasts, schedules, and other paperwork.

The original Rolex GMT Master has a fourth 24-hour hand directly displaying the same time zone as the standard 12-hour hand but on a 24-hour scale. This GMT hand enabled the crews to set the watch to GMT or another time zone, and, using the rotatable 24-hour scale bezel, set to the correct offset thus displaying a second-time-zone on the 24-hour scale.

This modern classic is absolutely stunning and would make a great stand-alone piece or a great addition to an existing collection!

The case is believed to remain unpolished showing honest signs of use and retains its factory finishing and chamfers down the lugs. The "Coke" bezel insert is in overall excellent vintage condition, showing only light signs of use, and remains bright red and deep black in coloration. The Rolex 78350 Oyster bracelet with 501B end pieces is unpolished as well showing honest signs of use, almost no stretch, and retains 12 links.


The glossy black dial with white gold surround markers is in flawless original condition, showing no imperfections or signs of aging. The tritium lume plots remain bright, showing a slight ivory patina in the sunlight, and exhibit no degradation when inspected under U.V. light. The original tritium hands match the dial perfectly, under U.V. light inspection the minute hand and the top third of the Mercedes hour hand show some very minor cracking and remain stable.


None. The watch was recently serviced and is running at COSC spec, backed by a 1-year warranty of accurate timekeeping.
