The GMT-Master II has an instantly recognizable design with a graduated bezel insert, which is available in various dual-colour combinations – the lower half symbolizing daytime and the upper signalling night-time. With traditional hour, minute and seconds hands, its triangle-tipped 24-hour hand and bidirectional rotatable bezel with 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 the 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 manufactured by Rolex. A consummate demonstration of technology, it offers outstanding performance in terms of precision, power reserve, convenience and reliability. It is fitted with the exclusive blue Parachrom hairspring and also incorporates the patented Chronergy escapement. The movement’s power reserve extends to approximately 70 hours.

The Cerachrom bezel insert is 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 a 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.

Over the years, Rolex presented other colour combinations: brown and black in 2018, green and black in 2022 – on a version with the crown and crown guard on the left side of the case and the date display at 9 o’clock – and grey and black in 2023.
