In 1954, Rolex launched the GMT-Master reference 6524 in
collaboration with the famous Pan Am company. The model
has gone on to become the benchmark for GMT watches. The
watch has gradually undergone various iterations ever since.

Innovation has inched forward without ever affecting the
iconic status of the model. In 1955, the graduated 24-hour disc
of the GMT-Master’s bicolour bezel – which has since become
more than emblematic – was made of Plexiglas. In 1959, it was
made of anodised aluminium. In 2005, high-tech ceramic arrived
on the scene with the GMT-Master II. In 2007, the bezel
and bezel disc were crafted from a single piece of what officially
became known as “Cerachrom”, the name given to the inhouse
technology. The numerals and graduations are moulded
in solid material and PVD-plated with gold or platinum. The
piece is UV-resistant.
