To truly appreciate the Rolex GMT-Master II 116710, we must first understand its rich heritage. The GMT-Master line was born from a collaboration between Rolex and Pan American Airways in the early 1950s. Pilots needed a watch capable of displaying two time zones simultaneously – local time and Greenwich Mean Time (GMT), the standard reference time for aviation. In 1955, Rolex introduced the first GMT-Master, reference 6542. This groundbreaking watch featured a rotating 24-hour bezel and a dedicated 24-hour hand, allowing pilots to effortlessly track a second time zone. Over the decades, the GMT-Master evolved through various iterations, each building upon the legacy of its predecessor. The GMT-Master II, introduced in 1982, marked a significant advancement with its independent setting of the hour hand, enabling the wearer to adjust local time without stopping the seconds hand or disturbing the 24-hour hand and bezel. This made tracking multiple time zones even more convenient and practical. The lineage leading up to the 116710 included models with aluminum bezels and painted markers, each with its own charm and collectibility. However, the introduction of the 116710 in 2007 signaled a new era, bringing ceramic into the GMT-Master realm and solidifying its position as a modern icon.
