The Rolex GMT-Master has earned its reputation as one of the most significant and revered watches of the modern era, with its origins tracing back to the 1950s. Originally conceived as a practical tool for pilots and frequent travelers, the GMT-Master allowed its wearer to track two time zones simultaneously, thanks to an additional 24-hour hand. Introduced in 1980, reference 16758 was the yellow gold counterpart to the stainless steel 16750. Both models were equipped with the upgraded caliber 3075, featuring a quick-set date function and improved water resistance up to 100 meters. Notably, the 16758 marked a luxurious evolution of the GMT-Master line, becoming the first model in the series to feature a sapphire crystal. The present Rolex GMT-Master reference 16758, produced around 1987, represents a more opulent take on this classic professional timepiece. While it retains all the defining features of the GMT-Master, it is elevated by a charming 18K yellow gold case, which imparts a distinct and refined character. Paired with a striking Oyster bracelet, the watch takes on an added layer of elegance. The rich “chocolate” brown sunburst dial, complemented by the exquisitely faded “root beer” bezel insert, creates a captivating contrast that further enhances the allure of the gold case. With its robust proportions, well-preserved lugs, and charismatic dial, this example remains a highly desirable addition to any serious collection.
