Rolex GM-Master II: A new look

The first of the new GMT-Master II versions introduced in 2018 is in Oystersteel. It is fitted onto a five-link Jubilee bracelet, and has a bidirectional rotatable bezel and a 24-hour graduated two-colour Cerachrom insert in red and blue ceramic, calling to mind the colours used on the original GMT-Master in 1955. It is the first time that the Jubilee bracelet, Oystersteel and the two-colour Cerachrom insert in red and blue ceramic have been brought together on the GMT-Master II.

Two further new versions introduce 18 ct Everose gold to the GMT-Master II range. One is made entirely from 18 ct Everose gold, while the other is an Everose Rolesor version – combining Oystersteel and 18 ct Everose gold. Both watches are equipped with a 24-hour graduated two-colour Cerachrom insert in a black and a newly developed brown ceramic. On the dial, the GMT-Master II inscription is in powdered rose. All three new versions have black lacquer dials. The highly legible Chromalight hands and hour markers (long-lasting luminescence, blue glow) are in 18 ct white or pink gold. On the Oystersteel version the 24-hour hand is coated with red lacquer.

The bracelets on the new GMT-Master II are equipped with the Easylink rapid extension system. This system, patented by Rolex in 1996, allows the wearer to increase the bracelet length by 5 mm, providing additional comfort. They are also fitted with an Oysterlock safety clasp, a sophisticated mechanism that prevents accidental opening. The bracelets also benefit from a concealed attachment system, ensuring seamless visual continuity between the bracelet and case. The GMT-Master II, Superlative Chronometer Like all Rolex watches, the GMT-Master II is covered by the Superlative Chronometer certifi – cation. This exclusive designation testifies that each watch has successfully undergone a series of tests conducted by Rolex in its own labora – tories according to its own criteria, which exceed watchmaking norms and standards. The certifica – tion applies to the fully assembled watch, after casing the movement, guaranteeing superlative performance on the wrist.

With 10 patent applications filed over the course of its development, this self-winding mechanical movement is a consummate demonstration of Rolex technology, at the forefront of the art of watchmaking. Calibre 3285 offers fundamental gains in terms of precision, power reserve, resistance to shocks and magnetism, convenience and reliability. Calibre 3285 incorporates the Chronergy escapement patented by Rolex, which combines high energy efficiency with great dependability. Made of nickel-phosphorus, it is also insensitive to magnetic interference. An optimized blue Parachrom hairspring is fitted to the oscillator, the true heart of the watch.

Manufactured by Rolex in an exclusive paramagnetic alloy, it is up to 10 times more precise than a traditional hairspring in case of shocks. A Rolex over coil ensures its regularity in any position. Calibre 3285 is equipped with a self-winding module via a Perpetual rotor. Thanks to its new barrel architecture and the escapement’s superior efficiency, the power reserve of calibre 3285 extends to approximately 70 hours.
