Oyster Perpetual GMT-MASTER II
May 02, 2018
THE COSMOPOLITAN WATCH
Rolex is extending its GMT-Master II range with a new version in Oystersteel, equipped with a bi- directional rotatable bezel and a 24-hour graduated two-colour Cerachrom insert in red and blue ceramic. The lugs and sides of its Oyster case have been redesigned, and the watch is fitted on a five-link Jubilee bracelet.
Two other versions of the GMT-Master II introduce 18 ct Everose gold to the range for the very first time. The first is crafted entirely from this refined, exclusive alloy, and the second is avail- able in an Everose Rolesor version, combining Oystersteel and 18 ct Everose gold. On the dials of both watches, the name “GMT-Master II” is inscribed in powdered rose. The bezels are fitted with two-colour Cerachrom inserts in a black and newly developed brown ceramic.
These new versions are equipped with the new-generation calibre 3285, at the forefront of watchmaking technology. With 10 patent appli- cations filed over the course of its development, the movement is equipped with a Chronergy escapement and guarantees a power reserve of approximately 70 hours.
Like all Rolex watches, the new versions of the GMT-Master II carry the Superlative Chronometer certification, which ensures excellent performance on the wrist.
ONE INSTRUMENT, SEVERAL TIME ZONES
Originally designed to aid airline pilots in their navigation, the GMT-Master has become an unmistakable icon. Over the years its emblem- atic bezel has been presented in various colours, in both single and two-coloured combinations. It is the signature feature of its unique and instantly recognizable aesthetics.
With a traditional hour, minute and seconds display via hands; a 24-hour hand; and a bidirec- tional rotatable bezel with a 24-hour graduated Cerachrom insert, it is possible to read the time in two time zones at once: either the local time and a reference time, or the local time and another time zone as desired. The date, shown at 3 o’clock, is synchronized with the local time display.
Since 2005, Rolex has played a pioneering role in the development of special ceramics for monobloc bezels and bezel inserts. These new materials are exceptionally resistant to scratches and corrosion, and offer particularly intense colours that are un- affected by ultraviolet rays. Rolex made full use of its expertise in developing the high-technology production methods that allow it to manufacture its ceramic components independently in-house.
Rolex is able to create these ceramics in single colours as well as two-colour versions. The
Cerachrom insert in red and blue ceramic is the most iconic of these, as it calls to mind the col- ours chosen for the first GMT-Master, launched in 1955.
This ceramic insert is a feat in terms of applied research and engineering. The challenge to create the insert’s red hue, which cannot be obtained using stable mineral pigments, led to the development of a complex internal process and the filing of several patent applications.
