The Cosmograph Daytona

Oyster Perpetual

COSMOGRAPH DAYTONA

The emblematic style and technical performance of the Cosmograph Daytona
have cemented its iconic status well beyond the motor racing circuits.
To mark the 60th anniversary of the watch, Rolex ensures the legend lives on
by revisiting the entire range.

Launched in 1963, the Cosmograph Daytona was designed to meet the needs of professional racing drivers. Fitted with a tachymetric bezel and a high performance mechanical movement entirely developed and manufactured by Rolex, this now legendary chronograph is the instrument of choice for measuring time intervals and determining average speeds. Through its name and functions, the Cosmograph Daytonais forever linked to the world of motor sport and, 60 years after its launch, continues to boast unparalleled status among sport chronographs.

HIGH-TECHNOLOGY CERAMIC

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.

HIGH-TECHNOLOGY CERAMIC

Among the versions of the new-generation Cosmograph Daytona presented, the one fashioned in 950 platinum, recognizable by its ice blue dial, is equipped with a monobloc Cerachrom bezel in chestnut brown ceramic. On the variant in Oystersteel with a white lacquer dial, and the watch in 18 ct yellow gold with a golden dial and bright black counters, the Cerachrom bezel is in black ceramic.

The recessed graduations, numerals and inscriptions on the tachymetric scale are moulded then coated with a thin layer of platinum or yellow gold via a PVD (Physical Vapour Deposition) process.

THE OYSTER CASE, SYMBOL OF WARTERPROOFNESS

A paragon of robustness and reliability, the 40 mm Oyster case
of the new-generation Cosmograph Daytona 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, 18 ct yellow or Everose gold, or 950 platinum. 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, along with the chronograph pushers. The crystal
is made of virtually scratchproof sapphire and benefits from an
antireflective coating. The waterproof Oyster case provides optimal
protection for the movement it houses.

PERPETUAL CALIBRE 4131 

The new-generation Cosmograph Daytona is equipped with calibre 4131, a chronograph movement unveiled this year, entirely developed and manufactured by Rolex. A distillation of technology, this self-winding mechanical movement delivers outstanding performance in terms of precision, power reserve, convenience and reliability. It incorporates a chronograph function with a reduced number of components, thereby also enhancing the movement’s reliability. It is engaged by a robust mechanism with a column wheel and vertical clutch, allowing an instantaneous and extremely precise start. The bridges of calibre 4131 feature a Rolex Côtes de Genève decoration, which differs from the traditional Côtes de Genève by the addition of a slight polished groove between each band.

OYSTER AND OYSTERFLEX BRACELETS

The Oyster bracelet and the Oysterflex bracelet of the Cosmograph Daytona are both equipped with the Oysterlock folding safety clasp, which prevents accidental opening. The Oyster bracelet features the Easylink comfort extension link, developed by the brand, which allows the wearer to easily adjust the bracelet length by approximately 5 mm. On the version in 950 platinum and that in 18 ct Everose gold, the bracelet also includes patented ceramic inserts – designed by Rolex – inside the links to enhance its flexibility on the wrist and its longevity.

The Oysterflex bracelet, for its part, 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 adjustments of the bracelet length, without the need for tools. The Rolex Glidelock on the Oysterflex bracelet has six notches of approximately 2.5 mm, allowing the length of the bracelet to be adjusted easily up to some 15 mm.

SUPERLATIVE CHRONOMETER CERTIFICATION

Like all Rolex watches, the Oyster Perpetual Cosmograph Daytona 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.
