1976 Rolex Two-Tone GMT-Master (Ref. 1675) Black Dial

The Rolex GMT-Master, a symbol of sophistication and versatility, has a storied history that dates back to 1954. It all started when Rolex received a request from Pan American Airways (Pan Am) to develop a technical pilot's watch capable of displaying two time zones simultaneously. With the advent of commercial transcontinental flights, Pan Am needed a watch for their long-haul international flight crews that would enable them to keep track of time in multiple locations.

Rolex GMT Master 1675 AD

GMT, which stands for Greenwich Mean Time, is the universal time standard that regulates the world's clocks and is the basis for aviation planning and schedules. The Rolex GMT-Master has a fourth 24-hour hand that displays the same time zone as the standard 12-hour hand but on a 24-hour scale. This GMT hand allows wearers to set the watch to GMT or any other time zone and then adjust the offset using the rotating 24-hour bezel to display a second timezone. This remarkable feature makes the Rolex GMT-Master a must-have for anyone who frequently travels across multiple time zones, allowing them to keep track of two time zones with ease and precision.

The excellent case is believed to have been professionally polished in the past to display thick and symmetrical factory-like dimensions, angles, and chamfers. The black and gold bezel insert displays minimal fading with subtle elements of age and use. The era-correct Rolex two-tone 78360 Oyster bracelet with 458 end pieces was sourced with the watch and retains 12 links that show minimal stretch and will fit up to a 7 1/2-inch wrist.


The original applied logo black nipple dial is in lovely vintage condition, showing gentle elements of age such as some clipping to the gold printed minute track but otherwise shows no notable damage. The tritium lume plots have achieved a deep golden patina and exhibit no degradation under UV light inspection. The original tritium hands match the dial perfectly, under UV light inspection the hands exhibit some superficial surface cracking and remain stable with no actual degradation present. The date wheel is likely an early service unit with "closed" 6's and 9's.


None. The watch is keeping time, but the service history is unknown. A movement service can be provided upon request.
