Dial A graphical and colourful motif
In the subtlest yet most modern way, the dial of the Oyster Perpetual 36 revisits the Jubilee motif introduced at the end of the 1970s, which has since become iconic. It displays the letters of the Rolex name in a contrasting interplay of no fewer than ten colours. Executing this pattern presents a significant challenge, as the colours are applied not all at once, but one after the other. The utmost precision is also required to ensure that all the shapes and letters making up the motif are positioned perfectly.
Oystersteel An exclusive alloy
The new version of the Oyster Perpetual 36 is crafted from Oystersteel. This special alloy with outstanding sheen is exclusively produced for Rolex. It belongs to the 904L steel family. These alloys are most commonly used in high-technology environments, such as the aerospace and chemical industries. Their excellent anti-corrosion properties are comparable to those of precious metals.
Oyster case A symbol of waterproofness
The Oyster case of the Oyster Perpetual 36 is guaranteed waterproof to a depth of 100 metres (330 feet). The middle case is crafted from a solid block of Oystersteel and crowned with a domed bezel. Its case back, edged with fine fluting, is hermetically screwed down with a special tool employed by approved watchmakers. The Twinlock winding crown, fitted with a double waterproofness system, screws down securely against the case. The crystal is made of virtually scratchproof sapphire and benefits from an anti-reflective coating.
Oyster bracelet Iconic and robust
Developed in the late 1930s, the Oyster bracelet is fitted on all the watches in the Oyster Perpetual range. Robust, comfortable and elegant, this metal bracelet comprises rows of three broad and slightly curved links. The Oyster bracelet on the Oyster Perpetual 36 is equipped with an Oysterclasp and also includes the Easylink comfort extension link, which allows the wearer to easily adjust the bracelet length by approximately 5 mm for instant additional comfort.
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.
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.

Calibre 3230 A distillation of technology
The Oyster Perpetual 36 is equipped with calibre 3230, a movement entirely developed and manufactured by Rolex. This self-winding mechanical movement, which incorporates a blue Parachrom hairspring and the Chronergy escapement, delivers outstanding performance, particularly in terms of precision, autonomy, convenience and reliability. It offers a power reserve of approximately 70 hours thanks to its barrel architecture and the escapement’s superior efficiency.
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. 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.
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.
Superlative Chronometer certification
The Oyster Perpetual 36 is covered by the Superlative Chronometer certification. This exclusive designation is issued to each watch leaving the Rolex workshops, attesting to its excellent performance on the wrist. This in-house certification is strictly controlled by internationally recognized, independent Swiss entities.
In 2026, the Superlative Chronometer certification has been strengthened with the addition of three new testing criteria: resistance to magnetism, reliability and sustainability. These criteria are implemented throughout the design and manufacturing stages of each timepiece – hundreds of checks and validations directly related to the watch’s performance are carried out during these phases. They supplement the criteria established when the certification was redefined in 2015 governing precision, waterproofness, self-winding and power reserve. That year, Rolex set up an exclusive testing protocol for its finished watches, conducted inside the manufacture on fully automated equipment. The precision requirements are particularly stringent: measured after casing the movement, the watch’s accuracy must be between –2 and +2 seconds per day. The rate deviation tolerated by the brand for the precision of a finished watch is significantly smaller than that accepted 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.
