Launched in 1954, Rolex developed the GMT-Master in association with the world renowned airline, Pan American Airways. During the early era of jet travel, the watch was developed to suit the needs of pilots flying long distances across continents, allowing them to simultaneously keep track of time in two time zones. Following the first generation reference 6542, Rolex introduced the reference 1675 now incorporating crown guards, a more durable metallic bezel insert, and the famous “Superlative Chronometer Officially Certified” printing on the dial. Housed in an 18 karat yellow gold case, the present example features a caramel color dial with nipple-shaped luminous hour markers and a matching bezel that provide a seductive harmony of color together with the gold case.
