GMT Master luxury watches
In contrast to the Explorer, which is for land, and the Submariner, which is for sea, this watch was developed in the 1950s as a pilot's watch with a sky-conscious concept. It was officially adopted by Pan American (Pan Am) at the time to support pilots on international routes who needed to keep track of two different time zones. While the GMT-Master I only displayed two time zones, the GMT-Master II, with its rotating bezel, allows for a three-time zone display. The bezel color also sets it apart from other models, with the existence of a two-tone model being a major feature. New color variations are continually being released, and this model, which beautifully combines functional beauty with aesthetic beauty, has captivated many Rolex users.
