The 24-hour hand of the Oyster Perpetual GMT-Master II displays much more than just an alternative time zone. It points to another location that resonates with the wearer – a reminder of the emotions that accompany each traveller.

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

The black lacquer dial bears the inscription ‘GMT-Master II’ in green, echoing the colour of the triangle-tipped 24-hour hand – an element that features strongly in the model’s design.

The GMT-Master II 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.

Like all Rolex watches, the Oyster Perpetual GMT-Master II carries the Superlative Chronometer certification, which ensures excellent performance on the wrist.

Designed as a navigation aid for professionals criss-crossing the globe, over time 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 various dual-colour combinations – the lower half symbolizing daytime hours and the upper signalling nighttime hours – as well as in single-colour versions. The GMT-Master, a true ‘tool watch’, 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 a 24-hour graduated Cerachrom insert, the GMT-Master II can display the time in two time zones simultaneously: either the local time and a reference time, or the local time and that of an alternative time zone. The date is synchronized with the local time.

Rolex played a pioneering role in the development of special ceramics for creating monobloc bezels and bezel inserts. Not only are these materials virtually scratchproof, their colours are also of a rare intensity and are resistant to environmental effects. In addition, thanks to its chemical composition, the high-tech ceramic is inert and cannot corrode. Rolex has developed exclusive expertise and innovative manufacturing methods that grant it complete independence in the production of these ceramic components.

On the new versions of the GMT-Master II, the bidirectional rotatable bezel is fitted with a two-colour, 24-hour graduated Cerachrom insert in grey and black ceramic. The moulded, recessed graduations and numerals are coated with platinum via PVD (Physical Vapour Deposition). The bezel can also be turned with ease thanks to its knurled edge, which offers excellent grip.

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 versions presented is crafted from a solid block of Oystersteel. Its case back, edged with fine fluting, is hermetically screwed down with a special tool that allows only Rolex watchmakers to access the movement. 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 at 3 o’clock 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.

The GMT-Master II is equipped with calibre 3285, a movement entirely developed and manufactured by Rolex that was released in 2018 and introduced on the model the same year. 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-phosphorus, this escapement is resistant to strong magnetic fields. The movement is fitted with a blue Parachrom hairspring, manufactured by Rolex in a paramagnetic alloy. The hairspring offers great stability in the face of temperature variations as well as high resistance to shocks. It is equipped with a Rolex overcoil, ensuring the calibre’s regularity in any position. The oscillator is mounted on the Rolex-designed, patented high-performance Paraflex shock absorbers, increasing the movement’s shock resistance. Since 2023, the oscillating weight has been fitted with an optimized ball bearing.

Calibre 3285 is equipped with a selfwinding 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.

The GMT-Master II in Oystersteel with grey and black Cerachrom bezel insert is fitted on an Oyster bracelet or a Jubilee bracelet. Developed in the late 1930s, the Oyster bracelet is a three-piece link metal bracelet known for its robustness; it remains the most universal bracelet in the Oyster Perpetual collection. Supple and comfortable, the Jubilee bracelet is a five-piece link metal bracelet; it was specially created for the Oyster Perpetual Datejust, which was launched in 1945.

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


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). The 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.


The GMT-Master Il is the ultimate cosmopolitan watch. Designed for professionals criss-crossing the globe, It is the successor to the GMT-Master, the original model launched in 1955.

1955
Launch of the GMT-Master. This watch provided a tool for navigating between journey time points. With its dedicated 24‑hour hand and graduated, rotatable two-colour bezel, it enabled all those who constantly travelled in different time zones – airline pilots, ships’ captains, navigators, international businessmen and members of the Armed Forces – to know the time in two time zones at a glance.

1959
The two-tone bezel insert is made in aluminum instead of Plexiglas for increased resistance to scratches and shocks. The alloy is anodized to create the different colours on the surface and make the insert harder.

1982
New movement. Introduction of a new calibre that allowed the hour hand to be adjusted independently of the minute hand and 24-hour hand. The watch with the new movement was named the GMT-Master II. And the first version of the model bears a burgundy and black bezel insert to mark this change.

2005
First ceramic bezel insert. The GMT-Master II welcomes a bezel insert made of ceramic, a first on a Rolex watch. This high-technology ceramic is extremely hard, virtually scratchproof, and its colour is unaffected by ultraviolet rays. In addition, thanks to its chemical composition, it is inert and cannot corrode.

2022
Winding crown on the left. An unexpected reinterpretation of the GMT-Master II was revealed in 2022. The new version, with a green and black Cerachrom insert, stood apart from others in the range for having its winding crown on the left side of the case. The date window was also uniquely placed at 9 o’clock.

2024
Grey and black insert and Oystersteel. Rolex unveils two new versions of the GMT-Master II, both equipped with a Cerachrom bezel insert in grey and black ceramic. Made of Oystersteel, they offer more discreet colour tones, subtly revealing their personality by way of a green 24‑hour hand.
