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. The GMT-Master, a true "tool watch", evolved

continually, to offer increasing technical performance. In 1982, Rolex introduced a new movement that 

allowed the hour hand to be set independently of the other hands. To clearly mark this evolution, the

model fitted with optimised movement was named the GMT-Master II.

With traditional hour, minute and seconds hands, its triangle-tipped 24-hours hand

and bidirectional rotatable bezel ith a 24-hour graduated Cerachrom insert, the

GMT-Master II can display the time in two time zones simultaneously: either the

local time and the reference time, or local time and that of an alternative time

zone. 

The latest GMT-Master II is equipped with calibre 3285, a self-winding mechanical

movement entirely developed and maufactured by Rolex. A consummate

demonstration of technology, it offers outstanding performance in terms of

precision, power reserve, resistance to shocks, convenience and reliability. It is

fitted with the exclusive blue Parachrom hairspring and also incorporate the 

patented Chronergy escapement. The movement's power reserve extends to 

approximately 70 hours. 

HIGH-TECHNOLOGY CERAMIC

The Cerachrom bezel insert s manufactured in a single piece by Rolex from 

extremely hard ceramic. This high-tech material is virtually scratchproof and keeps

its vibrant colours over time. 

Rolex broke new ground in 2013 when it introduced its first two-colour, single-

piece ceramic bezel insert - blue on one half and black on the other. One year

later, the brand released the two-colour Cerachrom insert in red and blue - the 

GMT-Master's original colours. It carried out pioneering research to develop a red

ceramic corresponding to its aesthetic and quality criteria. 

In 2022, Rolex unveiled a novel version of the GMT-Master II. On this watch, the crown and crown guard

are on the left side of the case. The date aperture and the Cyclops lens have also moved and appear at 9

o'clock. Made from Oystersteel, this watch features a two-colour monobloc Cerachrom bezel insert in

green and black ceramic - a colour pairing never before seen on the model.
