Power Reserve, Rotating Bezel, Luminescent Hand, Luminescent Numeral
Although the Rolex GMT-Master was designed essentially for professional use, its combination of peerless functionality and rugged good looks has attracted a wider traveling public. As well as appreciating its ability to display different time zones, these travelers admire the robustness and versatile appearance that make the GMT-Master eminently suitable for globetrotting and indeed for any occasion.
- To preserve the beauty of its pink gold watches, Rolex created and patented an exclusive 18 ct pink gold alloy cast in its own foundry: Everose gold. Introduced in 2005, 18 ct Everose is used on all Rolex models in pink gold.
- The dial is the distinctive face of a Rolex watch, the feature most responsible for its identity and readability. Characterized by hour markers fashioned from 18 ct gold to prevent tarnishing, every Rolex dial is designed and manufactured in-house, largely by hand to ensure perfection.
- The Oyster bracelet is a perfect alchemy of form and function, aesthetics and technology, designed to be both robust and comfortable. It is equipped with a Oyster-lock folding clasp, which prevents accidental opening and the Easy-link comfort extension link, also exclusive to Rolex. This ingenious system allows the wearer to increase the bracelet length by approximately 5mm, providing additional comfort in any circumstance.
- The new calibre 3285, a new-generation movement entirely developed and manufactured by Rolex. With 10 patent applications filed over the course of its development, this movement features a Chronergy escapement and a guaranteed power reserve of approximately 70 hours. Like all Rolex Perpetual movements, the 3285 is a certified Swiss chronometer, a
designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. The 3285 is equipped with a Parachrom hairspring, offering greater resistance to shocks and to temperature variations. Its architecture, in common with all Oyster watch movements, makes it singularly reliable.
A 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 bi-directional rotatble 24-Hour graduated bezel. The distinctively colored 24-Hour hand displays the "home" reference time in a first time zone which can be read on the graduations on the bezel. The traveler's local time is easily set by "jumping" from hour to hour, thanks to an ingenious mechanism operated forwards or backwards independently of the minute and seconds hands. This allows travelers to adapt to their new time zone without affecting their precision of their timekeeping.
