A ref. 1675/8 GMT-Master with a rich matte brown 'nipple' dial and Oyster bracelet, beautifully preserved. The GMT-Master, initially developed for Pan Am pilots, is one of the great pillars of vintage sport Rolex. It was one of the earliest sport Rolex to embrace precious metal, a decision likely influenced by the heavily romanticized jet set culture in period. The 1675/8 brought a gold case into the updated and more robust successor to the model's initial reference, epitomizing the golden age of air travel.
