This is a wonderful two-tone Rolex GMT Master Reference 16753 circa 1980. The original black dial with gold gilt writing is pristine. The lume on the dial as well as the hands is all original. We believe the watch to be unpolished as the case is super strong and does not show signs of polishing. This watch has a quick set date and an acrylic crystal. The two-tone oyster bracelet is nice and tight with barely any stretch.
