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 perfect tonal harmony, which remains true under all lighting conditions, is achieved by using the same type of ceramic to produce both elements.
This new version of the GMT-Master II is mounted on an Oyster bracelet equipped with an Oysterlock safety clasp.
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.
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: 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.
HIGH-TECHNOLOGY CERAMIC
Rolex played a pioneering role in the development of special ceramics to create particular elements of its watch cases – notably monobloc bezels and monobloc bezel inserts. 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. Its case back, edged with fine fluting, is hermetically screwed down with a special tool employed by approved watchmakers. 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 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-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. 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, further enhancing the movement’s shock resistance.
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. Developed in the late 1930s, this three-piece link metal bracelet is known for its robustness.
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.
At first glance, the new Rolex Oyster Perpetual Datejust 31 glows with an almost hypnotic allure. The dial—a gradient of deep red fading to black—captures the very essence of twilight. Rolex describes it as a “communion of light and shade”, a poetic phrase that beautifully encapsulates both the spirit of the design and the mastery of its creation.
In a landscape where luxury watches often rely on restraint, this red ombré dial stands apart as a daring statement. Inspired by the fleeting warmth of sunset, it is a study in contrast—fire meeting shadow, brilliance meeting depth.
The Datejust Legacy: A Timeless Classic
Few watches embody enduring elegance quite like the Rolex Datejust. Since its introduction in 1945, the Datejust has remained an archetype of classic watchmaking—combining practicality with poise. It was the first automatic, waterproof chronometer wristwatch to display the date at 3 o’clock, revolutionizing wristwatch functionality.
Eighty years later, its appeal remains undimmed. Every new iteration is a dialogue between Rolex’s storied past and its forward-looking innovation. The 2025 red ombré model continues this legacy, adding a bold splash of color to an icon known for quiet confidence.
A Fiery First: The Red Ombré Dial
This is the first time Rolex has rendered the ombré dial in such a vivid, fiery tone. Originally introduced in 2019 and reserved for the Day-Date, the ombré design uses PVD (Physical Vapour Deposition) to create its distinctive gradient — a subtle yet striking play of color that intensifies toward the outer rim.
The red ombré dial on this Datejust 31 feels like molten gold meeting shadow — expressive yet elegantly restrained. Surrounding the dial are 46 brilliant-cut diamonds, framing the color like sparks at the edge of a flame. Ten more diamonds serve as hour markers, each set in 18 ct yellow gold, offering a luxurious rhythm of sparkle and hue.
The Oyster Case: Symbol of Strength and Elegance
The 31 mm Oyster case, crafted from a solid block of 18 ct yellow gold, reflects Rolex’s unmatched craftsmanship. Its proportions balance grace and durability—refined yet robust. The Twinlock winding crown ensures waterproofness up to 100 metres (330 feet), while the sapphire crystal with its Cyclops lens guarantees clarity and scratch resistance.
Every curve, polish, and surface of the case has been refined to capture light in motion. This is not merely a protective shell—it’s a statement of permanence.
Inside the Movement: Calibre 2236
At the heart of this watch beats the Rolex Calibre 2236, a self-winding mechanical movement entirely developed and manufactured by Rolex. Introduced in 2014, and fitted to this model since 2018, it remains one of the brand’s most advanced calibres for smaller timepieces.
Equipped with the Syloxi hairspring in silicon and the paramagnetic nickel-phosphorus escape wheel, the Calibre 2236 ensures resistance to shocks, temperature variations, and magnetic fields. Rolex’s patented Paraflex shock absorbers and Perpetual rotor guarantee optimal performance with a power reserve of approximately 55 hours.
In typical Rolex fashion, the technical brilliance remains discreet—hidden beneath a case back that needs no exhibition window to prove its worth.
The President Bracelet: Prestige Refined
Created in 1956 for the launch of the Day-Date, the President bracelet remains one of Rolex’s most recognizable and prestigious designs. Reserved exclusively for precious metal versions of the Datejust and Day-Date, it blends seamless comfort with iconic aesthetics.
The three-piece solid links, crafted in 18 ct yellow gold, feature polished center links and satin-finished outer links—a tactile reminder of Rolex’s dual mastery of craft and ergonomics. Inside, patented ceramic inserts enhance flexibility and longevity. The concealed Crownclasp ensures a flawless visual continuity.
The Superlative Standard
Every Rolex watch undergoes stringent in-house testing under the Superlative Chronometer certification, redefined by Rolex in 2015. This guarantees exceptional precision (−2/+2 seconds per day), waterproofness, and durability.
The hallmark green seal accompanying each watch is not merely symbolic—it represents Rolex’s five-year international guarantee and its pursuit of horological excellence.
Why It Matters: The New Expression of the Classic
The Datejust 31 red ombré isn’t just a new dial variation—it’s a confident evolution of a timeless silhouette. It brings emotion to engineering, warmth to precision, and a renewed sense of individuality to a collection that has long stood for universal elegance.
It’s a reminder that even within the disciplined world of Rolex, art and feeling still have their place.

In a world of fleeting trends, Rolex once again proves that true innovation lies not in change, but in evolution.
Three models in bold configurations. Original combinations of colours and materials elicit new emotions. The Oyster Perpetual Cosmograph Daytona, GMT-Master II and Sky-Dweller are unveiled with new dials that magnify their aura.
Rolex unveiled flamboyant new faces on three of its iconic models renowned for their technical sophistication and emblematic design.
Indelibly linked to the world of motor sport and the measurement of elapsed time, the Oyster Perpetual Cosmograph Daytona is arrayed with a resplendent turquoise blue lacquer dial punctuated by bright black counters. Crafted in 18 ct yellow gold, this new watch is crowned with a black Cerachrom bezel showcasing the celebrated tachymetric scale that plays a key role in the model’s identity, and is complemented by an Oysterflex bracelet with Oysterlock safety clasp.
A cosmopolitan watch designed for all those who criss-cross the globe, the Oyster Perpetual GMT-Master II is offered with a new dial, made from tiger iron. This natural stone, containing a combination of tiger’s eye, red jasper and hematite, has a fascinating hybrid appearance. The watch presented is in 18 ct Everose gold with a brown and black Cerachrom bezel insert. It is fitted on an Oyster bracelet, itself equipped with an Oysterlock safety clasp.
Sophisticated and elegant, the Oyster Perpetual Sky-Dweller is a constant companion to travellers the world over. This year, an 18 ct yellow gold version dons a sunray finished dial in bright green – an intense hue that marries beautifully with the colour of the watch. An additional touch of refinement is provided by the Jubilee bracelet, also in 18 ct yellow gold and fitted with an Oysterclasp.
Like all Rolex watches, the Oyster Perpetual Cosmograph Daytona, Oyster Perpetual GMT-Master II and Oyster Perpetual Sky-Dweller carry the Superlative Chronometer certification, which ensures excellent performance on the wrist.
HIGH-TECHNOLOGY CERAMIC
Rolex played a pioneering role in the development of special ceramics to create particular elements of its watch cases – notably monobloc bezels and monobloc bezel inserts. 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.
The Cosmograph Daytona in 18 ct yellow gold with turquoise blue lacquer dial features a monobloc Cerachrom bezel in black ceramic. On the GMT-Master II in 18 ct Everose gold with tiger iron dial, the bidirectional rotatable bezel is fitted with a two-colour, 24-hour graduated Cerachrom insert in brown and black ceramic.
On these two Cerachrom components, the recessed graduations, numerals and inscriptions are moulded and then, via a PVD (Physical Vapour Deposition) process, coated with a thin layer of metal – yellow gold for the tachymetric scale on the Cerachrom bezel of the Cosmograph Daytona and pink gold for the markings on the Cerachrom bezel insert of the GMT-Master II.
THE FLUTED BEZEL, A SIGNATURE FEATURE
The fluted bezel has been offered on many Classic models in the Oyster Perpetual collection since the invention of the Oyster case in 1926. Its fluting was originally used in screwing down the bezel against the middle case, thereby indirectly playing a part in waterproofness. Today, however, its role is mainly aesthetic, with each perfectly identical groove catching the light and creating myriad subtle reflections. Exclusively made in 18 ct gold or in 950 platinum, the fluted bezel is the result of the brand’s unique expertise and one of the pillars of its stylistic heritage.
The fluted bezel of the Sky-Dweller with bright green dial is fashioned from 18 ct yellow gold – the same material as its Oyster case and Jubilee bracelet.
THE OYSTER CASE, SYMBOL OF WATERPROOFNESS
A paragon of robustness, reliability and elegance, the Oyster case of the Cosmograph Daytona and GMT-Master II – both 40 mm in diameter – as well as that of the Sky-Dweller – 42 mm – 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 18 ct yellow or Everose gold. Its case back, edged with fine fluting, is hermetically screwed down with a special tool employed by approved watchmakers. Both the Triplock winding crown, fitted with a triple waterproofness system and protected by an integral crown guard, and the Twinlock winding crown, with a double waterproofness system, screw down securely against the case, as do the chronograph pushers on the Cosmograph Daytona. The crystal – featuring a Cyclops lens at 3 o’clock for enhanced legibility on models with the date function – is made of virtually scratchproof sapphire and benefits from an anti-reflective coating. The waterproof Oyster case of each of the three watches provides optimal protection for the movement it houses.
CALIBRES 4131, 3285 AND 9002
The Cosmograph Daytona, GMT-Master II and Sky-Dweller are driven by self-winding mechanical movements entirely developed and manufactured by Rolex. A distillation of technology, they deliver outstanding performance, particularly in terms of precision, power reserve, convenience and reliability.
The Cosmograph Daytona is equipped with calibre 4131, which enables the watch to measure intervals of time via the chronograph function, in addition to displaying the hours, minutes and seconds. Released in 2023, it was introduced on the model the same year and is exclusive to this watch. Calibre 4131 demonstrates carefully finished aesthetics, including bridges decorated with Rolex Côtes de Genève and a cut-out oscillating weight.
The GMT-Master II has been fitted with calibre 3285 since the movement’s introduction in 2018. It provides the model with the date function and an additional time zone in 24-hour format, as well as the hours, minutes and seconds.
The Sky-Dweller is powered by calibre 9002, furnishing the watch with an annual calendar – date and month – and an additional time zone in 24-hour format, together with the hours, minutes and seconds. Introduced in 2023, calibre 9002 is exclusive to this model.
All three calibres incorporate the patented Chronergy escapement, which combines high energy efficiency with great dependability. Made of nickel-phosphorous, this escapement is resistant to strong magnetic fields. These movements are 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, further enhancing the movements’ shock resistance.
Calibre 4131, calibre 3285 and calibre 9002 are equipped with a self-winding system via a Perpetual rotor. Thanks to their barrel architecture and the superior efficiency of their escapement, the power reserve of these movements extends to approximately 72 hours, 70 hours and 72 hours respectively.
OYSTERFLEX, OYSTER AND JUBILEE BRACELETS
The Cosmograph Daytona with turquoise blue lacquer dial and bright black counters is fitted on an Oysterflex bracelet. Developed by Rolex and patented, this bracelet is made up of two flexible, curved metal blades – one for each of the sections – overmoulded with high-performance black elastomer.
The GMT-Master II with dial in tiger iron is mounted on an Oyster bracelet. Developed in the late 1930s, this three-piece link metal bracelet is known for its robustness.
The Sky-Dweller with bright green dial features a Jubilee bracelet. Supple and comfortable, this five-piece link metal bracelet was specially created for the Oyster Perpetual Datejust, launched in 1945.
The Oysterflex bracelet of the Cosmograph Daytona and the Oyster bracelet of the GMT-Master II are each equipped with the Oysterlock folding safety clasp, which prevents accidental opening, while the Jubilee bracelet of the Sky-Dweller is fitted with a folding Oysterclasp.
The Oysterflex bracelet is furnished with the Rolex Glidelock extension system. Developed by the brand and patented, this inventive mechanism with a rack located under the clasp cover enables fine adjustment of the bracelet length, without the need for tools. The Rolex Glidelock on the Oysterflex has six notches of approximately 2.5 mm, allowing the length of the bracelet to be effortlessly adjusted up to some 15 mm.
The Oyster bracelet of the GMT-Master II and the Jubilee bracelet of the Sky-Dweller feature the Easylink comfort extension link, developed by the brand, which allows them to be easily lengthened by approximately 5 mm. Made of 18 ct Everose gold and 18 ct yellow gold respectively, they include patented ceramic inserts – designed by Rolex – inside the links to enhance their flexibility on the wrist and their longevity.

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.
The perfect match
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 perfect tonal harmony, which remains true under all lighting conditions, is achieved by using the same type of ceramic to produce both elements.
This new version of the GMT-Master II is mounted on an Oyster bracelet equipped with an Oysterlock safety clasp.
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.
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: 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.
High-technology ceramic
Rolex played a pioneering role in the development of special ceramics to create particular elements of its watch cases – notably monobloc bezels and monobloc bezel inserts. 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. Its case back, edged with fine fluting, is hermetically screwed down with a special tool employed by approved watchmakers. 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 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-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. 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, further enhancing the movement’s shock resistance.
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. Developed in the late 1930s, this three-piece link metal bracelet is known for its robustness.
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.
