The GMT Master II reference 16710 is an updated version of the original GMT Master watch that was introduced in 1954. This newer model features an updated slimmer case paired with a meticulously designed 3185 Swiss certified self-winding movement. Originally designed in collaboration with Pan American Airways as a tool for professional pilots, the GMT Master II is equipped with a 24-hour rotatable bezel that works in coordination with the distinctive red GMT hand. The GMT hand circles the dial once every 24 hours to help the wearer keep track of two time zones at once, a feature that is highly desirable to pilots and world travelers. The GMT hand in the updated GMT Master II model can be independently adjusted from the other hands without affecting the current time. The Rolex GMT is a true classic and this is your chance to own one today!
