Released in 1954, the Rolex GMT-Master resulted from a collaboration between now-extinct airline Pan Am and Rolex on a watch that would display the time across two time zones at once. Thanks to the popularisation of commercial air travel, planes were becoming more advanced and traveling longer distances. This resulted in pilots crossing time zones during flights more frequently, and thus a need for uniformity across the aviation industry was highlighted. To eliminate errors caused by time confusion, the industry adopted a standard time-zone, Greenwich Mean Time. As such, the GMT-Master's fourth hand, its 2nd hour hand, was used to constantly display Greenwich Mean Time, as its model name implies, while its regular hour hand displayed local time. While the aviation industry's standard time-zone switched to Coordinated Universal Time (UTC) in 1972, the name of the legendary GMT-Master was far too long in use for Rolex to change it. Today, the GMT-Master has become one of Rolex's most iconic models, with very few pilot's watches, if any, rivaling its level of fame, popularity, or signature design – and it certainly looks like it will stay that way.

Watch is in excellent overall condition. Case shows some wear and previous signs of polishing. Minor marks and scratches visible along the case. The bezel insert has some light oxidation as visible in the images. The surface is slightly matted in texture. Black nipple dial is excellent, with nicely aged luminous that matches the hands. The watch comes on an 18k hidden clasp jubilee bracelet with 22 links, 2 of which are removable. There is light notching visible on some center links and the band displays light to moderate stretch.

Blending luxury with utility, the ref. 16758's 18kt yellow gold construction and useful functions combine to offer a truly beautiful design that is both practical and stylish.
