Introduced in the early 1980s, the GMT-Master reference 16750 holds a distinctive place in Rolex's professional lineup as the model that first brought the quickset date function to the GMT-Master family. At 40mm in stainless steel, the Oyster case carries a 24-hour graduated red and blue aluminum bezel insert — the configuration collectors have long called "Pepsi" — alongside an acrylic crystal that keeps the watch true to its transitional-era character. A screw-down Twinlock crown contributes water resistance to 100 meters.
The black dial is the defining feature of this particular example: decades of natural aging have transformed the tritium hour markers and hands, imparting a warm patina that only time can produce. That contrast between the aged dial and the vivid Pepsi bezel is precisely what draws collectors to vintage GMT-Masters of this generation. The stainless steel Oyster bracelet, built with folded-link construction, reinforces the utilitarian spirit that defined Rolex's tool watches of the era.
Beneath the case runs the self-winding Caliber 3075, an automatic movement with roughly 48 hours of power reserve whose quickset date mechanism — advancing the date independently via the crown — was a meaningful step forward from earlier GMT calibers. The movement also drives an independently adjustable GMT hand, enabling the simultaneous reading of a second time zone. This watch is offered in vintage condition with its Rolex box and a 2-year warranty included.
