Pre-owned Rolex GMT-Master II ref. 16710 (2005 – 2006) is widely regarded as one of the defining references in the history of the GMT-Master collection. The model traces its roots back to the 1950s, when Rolex developed the original GMT-Master for international airline pilots and paired it with a red and blue bezel insert to distinguish daytime and nighttime hours at a glance. That iconic “Pepsi” color scheme is still one of the most recognizable designs in all of watchmaking. When Rolex introduced the GMT-Master II in the 1980s, the collection gained an independently adjustable GMT hand, allowing for more flexible time zone tracking. Early examples featured a thicker case to accommodate the new movement, but the ref. 16710 refined the formula with a slimmer caliber and more balanced proportions. The result was a watch that retained all the functionality of its predecessor while becoming noticeably more comfortable on the wrist. Shop Rolex GMT-Master II Collection
