This GMT Master II is indeed a legend of the jet age, the original GMT-Master was embraced by airline pilots as their on-board navigation chronometer.Easily the most iconic two-time-zone watch, it features an arrow-tipped 24-hour hand and a graduated rotatable bezel. This example is a bit of a unique example though. The 24 hour bezel has been replaced with a sapphire, ruby and diamond bezel. This adds a punch of personality and decadence rarely seen in this watch. This watch was service by Rolex in 2016 and comes with papers only.
