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.
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.

|Rolex 78360 Oyster Bracelet W/ 580 End Pieces
The strong case retains thick, symmetrical lugs and has been gently polished in the past, now showing light signs of honest use. The blue back "Pepsi" bezel insert is in superb condition, showing no age or wear. The later Rolex 78360 Oyster bracelet with 580 end pieces retains 13 links that show minimal stretch and will fit up to an 8-inch wrist.
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.
