24-Hour Rotatable Bezel
In addition to conventional hour, minute and seconds hands, the GMT-Master II features an arrow-tipped hand, which circles the dial once every 24 hours, as well as a bidirectional rotatable 24-hour graduated bezel. The distinctively coloured 24-hour hand displays the “home” reference time in a first time zone which can be read on the graduations on the bezel. The traveller’s local time is easily set by “jumping” from hour to hour, thanks to an ingenious mechanism operated via the winding crown: the hour hand can be adjusted forwards or backwards independently of the minute and seconds hands. This allows travellers to adapt to their new time zone without affecting the precision of their timekeeping.
Like all Rolex Professional watches, the GMT-Master II offers exceptional legibility in all circumstances, and especially in the dark, thanks to its Chromalight display. The broad hands and hour markers in simple shapes – triangles, circles, rectangles – are filled with a luminescent material emitting a long-lasting glow.
Rolex uses Oystersteel for its steel watch cases. Specially developed by the brand, Oystersteel belongs to the 904L steel family, alloys most commonly used in high-technology and in the aerospace and chemical industries, where maximum resistance to corrosion is essential. Oystersteel is extremely resistant, offers an exceptional finish once polished and maintains its beauty even in the harshest environments.
All Rolex watches are assembled by hand with the utmost care to ensure exceptional quality. Such high standards naturally restrict Rolex production capacity and, at times, the demand for Rolex watches outpaces this capacity.
Therefore, the availability of certain models may be limited. New Rolex watches are exclusively sold by Official Rolex Jewelers, who receive regular deliveries and independently manage the allocation and sales of watches to customers.
Nam Sawang is proud to be part of the worldwide network of Official Rolex Jewelers and can provide information on the availability of Rolex watches.

Synonymous with excellence and reliability, Rolex watches are designed for everyday wear, and depending on the model, perfectly suited for a wide range of sports and other activities.

Learn more about its features and how to set the date and two time zones by watching the video.
The GMT-Master was made for airborne adventure. Now the watch of choice for travellers, it connects people beyond time zones. Rolex is unveiling a novel, unexpected version of the Oyster Perpetual GMT-Master II. On this watch, the crown and crown guard are on the left side of the watch case. This required several technical adjustments in terms of the movement and the Superlative Chronometer certification, for which the protocol, as well as some of the final tests, had to be adapted. The date aperture and the Cyclops lens have also moved and appear at 9 o’clock.
