Rolex GMT-Master II
The perfect match
New watches 2025
Rolex has chosen to introduce its very first ceramic dial on an 18 ct white gold version of the Oyster Perpetual GMT-Master II. In the same material, with the same green colour and the same lustre, this Cerachrom dial and the daytime half of the green and black bezel insert echo each other perfectly.
Rolex is introducing its first-ever dial made of high-technology ceramic.
This inaugural green Cerachrom component makes its debut on an Oyster Perpetual GMT-Master II with winding crown on the left side of the case and date aperture at 9 o’clock, a version which additionally, this year, is presented in 18 ct white gold.
The new Cerachrom dial – created in the same way as dials in natural stone, by fitting a disc of material onto a brass plate – displays the same shade of green as the lower half of the two-colour green and black Cerachrom bezel insert that frames the watch face.
This new version of the GMT-Master II is mounted on an Oyster bracelet equipped with an Oysterlock safety clasp.
The GMT-MasterII is driven by calibre 3285, a movement at the forefront of watchmaking technology, enabling it to display the date and an additional time zone in 24-hour format, as well as the hours, minutes and seconds.
One instrument, several time zones
Designed as a navigation aid for professionals criss-crossing the globe, the GMT-Master became the watch of choice for travellers. It has a unique and instantly recognizable design with a bidirectional rotatable bezel and a 24-hour graduated insert, which has been made available in single-colour versions as well as in various dual-colour combinations – the lower half symbolizing daytime hours and the upper signalling night-time hours. The GMT-Master, a true ‘tool watch’, has evolved continually to offer increasing technical performance. In 1982, Rolex unveiled the GMT-Master II, with a movement allowing the hour hand to be set independently of the other hands.
With traditional hour, minute and seconds hands, a triangle-tipped 24-hour hand, and a bidirectional rotatable bezel with 24-hour graduated Cerachrom insert, the GMT-Master II can display the time in two time zones simultaneously.
High-technology ceramic
Rolex played a pioneering role in the development of special ceramics to create particular elements of its watch cases. Not only are these materials particularly scratch resistant, their colours are also of a rare intensity and are resistant to environmental effects. In addition, thanks to their chemical composition, the high-tech ceramics are inert and cannot corrode. The brand has developed exclusive expertise and innovative manufacturing methods that grant it complete independence in the production of these ceramic components.
On the new version of the GMT-Master II, the bidirectional rotatable bezel is fitted with a two-colour, 24-hour graduated Cerachrom insert in green and black ceramic. The moulded, recessed graduations and numerals are coated with platinum via PVD (Physical Vapour Deposition). The bezel’s knurled edge offers excellent grip and can be manipulated with ease.
The Oyster case, symbol of waterproofness
A paragon of robustness and reliability, the 40 mm Oyster case of the GMT-Master II is guaranteed waterproof to a depth of 100 metres (330 feet). The middle case of the version presented is crafted from a solid block of 18 ct white gold. The Triplock winding crown, fitted with a triple waterproofness system and protected by an integral crown guard, screws down securely against the case. The crystal, which features a Cyclops lens for easy reading of the date, is made of virtually scratchproof sapphire and benefits from an anti-reflective coating. The waterproof Oyster case provides optimal protection for the movement it houses.
Calibre 3285
The GMT-Master II is powered by calibre 3285, a movement entirely developed and manufactured by Rolex. A distillation of technology, this self-winding mechanical movement delivers outstanding performance, particularly in terms of precision, power reserve, convenience and reliability.
Calibre 3285 incorporates the patented Chronergy escapement, which combines high energy efficiency with great dependability. Made of nickel-phosphorous, this escapement is resistant to strong magnetic fields. The movement is fitted with a blue Parachrom hairspring, manufactured by Rolex in a paramagnetic alloy.
Calibre 3285 is equipped with a self-winding system via a Perpetual rotor. Thanks to its barrel architecture and the escapement’s superior efficiency, the power reserve of this movement extends to approximately 70 hours.
Oyster bracelet and Oysterlock safety clasp
The GMT-Master II in 18 ct white gold with a green Cerachrom dial matched with the green and black Cerachrom bezel insert is fitted on an Oyster bracelet.
The Oyster bracelet of the GMT-Master II is furnished with the Oysterlock folding safety clasp, which prevents accidental opening. It also includes the Easylink comfort extension link, developed by Rolex, that allows the wearer to easily adjust the bracelet length by approximately 5 mm. On the version presented, it includes patented ceramic inserts – designed by the brand – inside the links to enhance its flexibility on the wrist and its longevity.
Superlative Chronometer certification
Like all Rolex watches, the Oyster Perpetual GMT-Master II is covered by the Superlative Chronometer certification redefined by Rolex in 2015. This designation testifies that every watch leaving the brand’s workshops has successfully undergone a series of tests conducted by Rolex in its own laboratories according to its own criteria, following the official certification of the movements by the Swiss Official Chronometer Testing Institute (COSC). These in-house certification tests apply to the fully assembled watch, after casing the movement, guaranteeing superlative performance on the wrist in terms of precision, power reserve, waterproofness and self-winding. The precision of a Rolex Superlative Chronometer is of the order of −2 /+2 seconds per day – the rate deviation tolerated by the brand for a finished watch is significantly smaller than that accepted by COSC for official certification of the movement alone.
The Superlative Chronometer status is symbolized by the green seal that comes with every Rolex watch and is coupled with an international five-year guarantee.
