Rolex has introduced two new Oyster steel versions of the Oyster Perpetual GMT-Master II. Both feature a two-tone 24-hour graduated Cerachrom insert in gray and black ceramic – introduced last year – whose graduation is clearly visible thanks to its platinum coating, applied via PVD (Physical Vapor Deposition). The first watch comes with an Oyster bracelet, while the second has a Jubilee bracelet.

The black lacquered dial bears the inscription 'GMT-Master II' in green, echoing the color of the triangular-pointed 24-hour indicator – an element that stands out in the model's design.

ONE TOOL, SEVERAL TIME ZONES

Designed as a navigation aid for professionals traversing the globe, over time the GMT-Master has become the watch of choice for travelers. It has a unique and instantly recognizable design with a bidirectional rotating bezel and 24-hour graduated insert, made available in various two-tone combinations – the lower half symbolizes daytime hours and the upper half indicates nighttime hours – as well as single-tone versions. The GMT-Master, a true “tool watch”, has continuously evolved to offer ever-improving technical performance. In 1982, Rolex introduced the GMT-Master II, with a movement that allows the time to be adjusted independently of the other hands.

With traditional hour, minute and second hands, a triangular-tipped 24-hour indicator and a bidirectional rotating bezel with a 24-hour graduated Cerachrom insert, the GMT-Master II can display the time in two time zones simultaneously: either local time and a reference time, or local time and that of an alternative time zone. The date is synchronized with local time.

BATHROOM CERAMIC

Rolex played a pioneering role in the development of specialty ceramics for creating monobloc bezels and bezel inserts. These materials are virtually scratch-proof and their colors are of a rare intensity and resist environmental effects. Furthermore, due to its chemical composition, high-tech ceramic is inert and cannot corrode.

In the new versions of the GMT-Master II, the bidirectional rotating bezel is equipped with a two-tone Cerachrom insert graduated at 24 hours in gray and black ceramic. The embossed graduations and numbers are coated with platinum via PVD (Physical Vapor Deposition). The bezel can also be turned easily thanks to its knurled edge, which offers excellent grip.

THE OYSTER CASE

A model of ruggedness and reliability, the GMT-Master II's 40mm Oyster case is guaranteed waterproof to a depth of 100 meters (330 feet). The central case of the versions presented is made from a solid block of Oystersteel. The case back, edged with a thin spiral cutout, is screwed down hermetically with a special tool that allows only Rolex master watchmakers to access the movement.

The Triplock screw-down crown, equipped with a triple water-resistance system and protected by an integrated crown, screws securely against the case. The crystal, which features a Cyclops lens at 3 o'clock for easy reading of the date, is made from virtually scratch-resistant sapphire and benefits from an anti-reflective coating. The waterproof Oyster case offers optimal protection for the movement it houses.

CALIBER 3285

The GMT-Master II is equipped with the caliber 3285, a movement entirely developed and produced by Rolex that was released in 2018 and introduced on the model in the same year. A distillation of technology, this automatic mechanical movement offers exceptional performance, particularly in terms of precision, power reserve, convenience and reliability.

The caliber 3285 incorporates the patented Chronergy escapement, which combines high energy efficiency with great reliability. Made of nickel-phosphorus, this anchor is resistant to strong magnetic fields. The movement is equipped with a blue Parachrom hairspring, produced by Rolex in a paramagnetic alloy. The spiral offers great stability in the face of temperature variations and high impact resistance. It is equipped with a Rolex balance wheel, ensuring the regularity of the caliber in any position. From 2023, the swing rotor is equipped with an optimized ball bearing.

The caliber 3285 is equipped with an automatic winding system via a perpetual rotor. Thanks to its barrel architecture and superior anchoring efficiency, the power reserve of this movement extends to approximately 70 hours.

OYSTER AND JUBILEE BRACELETS

The Oyster steel GMT-Master II with gray and black Cerachrom bezel insert is mounted on an Oyster bracelet or a Jubilee bracelet. Developed in the late 30s, the Oyster bracelet is a three-piece metallic bracelet known for its sturdiness; it remains the most universal bracelet in the Oyster Perpetual collection. Flexible and comfortable, the Jubilee bracelet is a five-piece metallic bracelet; it was specially created for the Datejust Oyster Perpetual, launched in 1945.

Both the Oyster bracelet and the Jubilee bracelet of the GMT-Master II are equipped with an Oysterlock folding safety clasp, which prevents accidental opening. They also feature the Easylink comfort extender, developed by Rolex, which allows the wearer to easily adjust the length of the bracelet by approximately 5 mm.

SUPERLATIVE CHRONOMETER CERTIFICATION

The accuracy of a Rolex Superlative Chronometer is on the order of -2 /+2 seconds per day – the rate deviation tolerated by the brand for a finished watch is significantly lower than that accepted by the COSC for official certification of the movement alone.

Superlative Chronometer status is symbolized by the green seal that accompanies every Rolex watch and is backed by a five-year international warranty.
