The Rolex GMT Master, originally designed in 1955, was developed to show the time in two different locations around the world simultaneously. In 1982, Rolex launched the GMT Master II. This model came with a new movement and instantly recognisable detailing, without sacrificing any of the original functionality that set the timepiece apart from other models. The Bezel can move in either direction to assist with setting the time of the local area you may be travelling to, as well as the additional arrow-headed 24-hour hand!
