Brief History of the Rolex GMT-Master 16750
The Ref. 16750 was produced from approximately 1981 to 1988 and is best known for introducing the Rolex Caliber 3075, which added a quick-set date function—an important usability improvement over earlier GMT movements. Early examples retained matte dials, while later production transitioned to glossy dials with applied white gold markers, making the 16750 a true crossover reference prized by collectors. Despite these updates, the watch maintained classic GMT-Master proportions and the acrylic crystal.
Movement: Rolex Caliber 3075
The Rolex Caliber 3075 is an automatic GMT movement featuring:
- Independent 24-hour GMT hand
- Quick-set date mechanism
