Introduced in 1955, the Rolex GMT-Master was designed in collaboration with Pan American Airways for its international flight crews. The watch features a distinctive 24-hour hand and a rotational bezel to allow crews to set the watch to GMT or another time zone. The model became famous for its reliability and versatility.
