The Oyster Perpetual GMT-Master II is designed to display the time in two different time zones simultaneously. Robust and functional, it is the ideal watch for criss-crossing the globe. Launched in 1955, the GMT-Master witnessed the rapid expansion of intercontinental travel in the latter half of the 20th century. It even became the official watch of Pan American World Airways, the most prominent American international airline at the time. Like all Rolex watches, the GMT-Master II is covered by the Superlative Chronometer certification. This designation testifies that every watch leaving the brand’s workshops has successfully undergone a series of tests conducted by Rolex in its own laboratories, according to its own criteria. The Superlative Chronometer status is symbolized by the green seal that comes with every Rolex watch and is coupled with an international five-year guarantee.
