Rolex celebrates GMT-Master 70th anniversary with exhibition
Hong Kong expo is heavy on history – as well as name dropping – as it explores the legacy of the iconic watch


Born in 1955, the GMT-Master was Rolex’s answer to a new era of travel. As jetliners shrank the world and passengers crossed multiple time zones in hours, the need for a reliable, easy-to-read second time zone became paramount. The GMT-Master’s signature two-colour 24-hour bezel and an additional hour hand allowed wearers to track home time and local time simultaneously – a breakthrough that quickly popularised the watch among pilots, explorers and travellers alike.
From the original Plexiglas bezel to the modern ceramic variants, and from the early calibre 1036 movement to today’s calibre 3285, the GMT-Master’s evolution mirrors that of Rolex, and the wider watch world’s, in terms of precision and durability.

Then there are the leaps in craftsmanship such as the watch’s luminescent Chromalight display, which was enhanced in 2021 for superior legibility, and the return of the Jubilee bracelet in 2018. The GMT-Master II’s independently adjustable hour hand, introduced in 1982, also marked a pivotal moment, allowing travellers to adjust local time without stopping the watch – a feature that has cemented its status as the ultimate tool watch.
