Rolex Oyster Perpetual Cosmograph Daytona

Rolex recently debuted its new-generation Oyster Perpetual Cosmograph Daytona, which has been updated across the entire range. The chronograph’s distinctive case and face design, which has distinguished it since its introduction, has been revised with a number of subtle improvements. New graphic balance is applied to the dial, and appealing colour schemes highlight the contrast between the dial and the counters, or their rings. The light reflections on the lugs and case sides draw attention to the revised Oyster case’s profile. The Cerachrom bezel is bordered with a thin band of the same metal as the middle case on models with a Cerachrom bezel.

The Cosmograph Daytona is outfitted with calibre 4131 from this year. The Chronergy escapement and other significant advancements made by Rolex to its movements are all included in this new chronograph movement, which is a development of calibre 4130. Aesthetics has received special consideration. The calibre has a cut-out oscillating weight and entirely unique finishes, most notably on the bridges where Rolex Côtes de Genève, the brand’s rendition of a well-known watchmaking ornament, are adorned. The Cosmograph Daytona’s Calibre 4131 allows it to measure time intervals using the chronograph feature in addition to displaying the hours, minutes, and seconds.

The Cosmograph Daytona in 950 platinum, a distinctive and iconic timepiece, is sporting a transparent case back and an oscillating weight made of 18 ct yellow gold.

The Oyster Perpetual Cosmograph Daytona, like other Rolex watches, is certified as a Superlative Chronometer, ensuring exceptional performance.

The Cosmograph Daytona was introduced in 1963 with the purpose of serving the requirements of professional racecar drivers. This now-famous chronograph, with with a tachymetric bezel and a high-performance mechanical movement wholly created and produced by Rolex, is the tool of choice for calculating average speeds and monitoring time intervals.

The Cosmograph Daytona is inextricably tied to the world of motorsport by its name and features, and 60 years after its introduction, it still has an unrivalled reputation among sports chronographs.

Rolex pioneered the development of special Ceramics for monobloc bezels and bezel inserts. These materials not only have colours of a remarkable intensity and resistance to environmental influences, but they are also practically scratchproof. The advanced ceramic is also inert and impervious to corrosion because of its chemical makeup. Rolex has created specialised knowledge and cutting-edge manufacturing techniques that give it total independence in the manufacture of these ceramic components.

The new-generation Cosmograph Daytona is available in several different configurations, but the one distinguished by its icy blue dial and made of 950 platinum has a monobloc Cerachrom bezel made of chestnut brown ceramic. The Cerachrom bezel is made of black ceramic on the Oystersteel variation with a white lacquer display and the 18 ct yellow gold watch with a golden dial and brilliant black counters. The recessed graduations, numerals, and inscriptions on the tachymetric scale are moulded, then a PVD (Physical Vapour Deposition) procedure is used to cover them with a thin layer of platinum or yellow gold.

The 40 mm Oyster case of the new-generation Cosmograph Daytona is a model of durability and dependability and is guaranteed to be waterproof to a depth of 100 metres (330 feet). The centre case of the variations shown is made from a solid block of oystersteel, 950 platinum, or 18 ct yellow or rose gold. Only Rolex watchmakers are able to access the movement through the case back, which is hermetically secured with a unique tool and edged with delicate fluting. Together with the chronograph pushers, the Triplock winding crown is screwed tightly against the case and equipped with a triple waterproof system and a built-in crown guard. The crystal has an anti-reflective coating and is constructed of sapphire, which is almost scratch-proof. The waterproof Oyster case provides optimal protection for the movement it houses.

The case of the Cosmograph Daytona in 950 platinum now has a sapphire transparent case back with an anti-reflective coating, allowing you to see the movement’s embellishments and how the oscillating weight pivots.

The calibre 4131, a chronograph movement launched this year and wholly created and produced by Rolex, is the heart of the new generation Cosmograph Daytona. Its self-winding mechanical movement is a technological distillation that offers exceptional performance in terms of accuracy, power reserve, convenience, and dependability. It integrates a chronograph function with fewer parts, increasing the movement’s dependability in the process. A strong mechanism with a vertical clutch and column wheel engages it, enabling a quick and exceptionally accurate start. The Rolex Côtes de Genève ornamentation on the bridges of the calibre 4131 deviates from the classic Côtes de Genève by including a little polished groove between each band.

The patented Chronergy escapement, used in Calibre 4131, combines remarkable energy efficiency with outstanding durability. Its escapement is resistant to severe magnetic fields because it is made of nickel-phosphorus. A blue Parachrom hairspring made by Rolex from a paramagnetic alloy is installed in the mechanism. The hairspring provides excellent stability under temperature changes and good shock resistance. It has a Rolex overcoil, which guarantees the regularity of the calibre in any setting. The high-performance Paraflex shock absorbers, which Rolex invented and patented, are installed on the oscillator to increase the movement’s shock resistance. The oscillating weight has an improved ball bearing installed.

Calibre 4131 is outfitted with a self-winding system using a Perpetual rotor. The calibre 4131’s power reserve is extended to roughly 72 hours by the greater efficiency of the escapement and the barrel construction.

The 950 platinum model of the new-generation Cosmograph Daytona that was unveiled this year is distinguishable by its ice blue dial and is mounted on an Oyster bracelet. Both the Oystersteel version and the yellow Rolesor version, which combines Oystersteel with yellow gold, have a white lacquer dial. The 18 ct Everose gold version is also available on an Oyster bracelet and features a vivid black dial and Sundust counters. Its three-piece link bracelet, which was created at the end of the 1930s, is renowned for its durability and is now the most popular style in the Oyster Perpetual line.

With a golden dial and brilliant black counters, the new model in 18 ct yellow gold is attached to an Oysterflex bracelet. This unique bracelet was created by Rolex and is protected by a patent. It is constructed of two flexible, curved metal blades, one for each segment, that have been over-moulded with high-performance black elastomer.

The Cosmograph Daytona’s Oysterflex and Oyster bracelets both have the Oysterlock folding safety clasp, which prevents inadvertent opening. The brand-developed Easylink comfort extension link, found on the Oyster bracelet, enables the wearer to quickly change the bracelet’s length by about 5 mm. The bracelet also features innovative ceramic inserts, created by Rolex, inside the links on the versions made of 950 platinum and 18 ct Everose gold to increase flexibility on the wrist and longevity.

The Rolex Glidelock extension system is included with the Oysterflex bracelet. This ingenious system, created and patented by the business, has a rack behind the clasp cover that allows for precise bracelet length modifications without the use of tools. With six 2.5 mm-wide notches on the Oysterflex bracelet’s Rolex Glidelock, the bracelet’s length may be simply altered up to 15 mm.
