1973 Rolex GMT-Master (Ref. 1675) Mk. IV W/ Rolex Papers, Hantag, & Accessories

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 pilot's 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.

Rolex GMT Pan Am 1675

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 edition 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 their home time zone, no matter how far they may have journeyed.

The matte black Mk. IV dial is in exceptionally well-preserved condition, showing no damage or age. The tritium lume plots have aged to a creamy patina, under U.V. light inspection the lume shows no degradation but exhibits a mark in the 12 o'clock plot. The original tritium hands match the dial perfectly, the 24hr hand has aged one shade darker, however, under U.V. light inspection the lume shows no degradation. The metallic date wheel is original with open 6's and 9's.


The watch comes complete with its original Rolex guarantee paper, serialized hangtag, and green Rolex document holder. The watch is recently serviced and is keeping time perfectly backed by a 1-year warranty on accurate timekeeping.
