THE LEGENDARY CHRONOGRAPH
Rolex is introducing a scintillant gem-set version of the Oyster Perpetual Cosmograph Daytona. Created in 1963, this watch has established an extraordinary track record in the world of motor sport, rising to the rank of an icon. On this new18 ct Everose gold version, in lieu of the emblem-atic tachymetric scale, the bezel is set with a gradation of sapphires in rainbow hues. The case is adorned with 56 brilliant-cut diamonds set into the lugs and crown guard, and the dial features 11 baguette-cut sapphire hour markers, each of which matches the colour of the corresponding point on the bezel. The chronograph counters are in pink Gold Crystals, a material with a particularshimmer effect, created during the crystallization of a pink gold alloy by means of a special processdeveloped by Rolex.
Like all Rolex watches, the new CosmographDaytona carries the Superlative Chronometer cer-tification, which ensures excellent performance on the wrist.
THE OYSTER CASE, SYMBOL OF WATERPROOFNESS
The Cosmograph Daytona’s Oyster case, guaranteed waterproof to a depth of 100 metres (330 feet), is a paragon of robustness and reli-ability. Its middle case, with an integral crown guard, is crafted from a solid block of 18 ct Everose gold. The case back, edged with fine fluting, is hermetically screwed down with aspecial tool that allows only Rolex watchmakers to access the movement. The winding crown, fittedwith the Triplock triple waterproofness system, screws down securely against the case, alongwith the chronograph pushers. The crystal is made of virtually scratchproof sapphire. The waterproof Oyster case provides optimum protection for the Cosmograph Daytona’s high-precision movement.
PERPETUAL CALIBRE 4130
The Cosmograph Daytona is equipped with calibre 4130, a self-winding mechanical chrono- graph movement entirely developed and manufactured by Rolex. A consummate demon- stration of Rolex technology, the movementincorporates a chronograph function with a reducednumber of components, thereby enhancing the movement’s reliability.
The robust chronograph is engaged by a mechanism with a column wheel and verticalclutch, providing an instant and extremely precisestart. The oscillator, the true heart of the watch,
has a blue Parachrom hairspring manufactured by Rolex in an exclusive paramagnetic alloy. Insensitive to magnetic fields, the Parachromhairspring offers great stability in the face of tem-perature variations and remains up to 10 times more precise than a traditional hairspring in case of shocks. A Rolex overcoil ensures its regular-ity in any position. Calibre 4130 is equipped with a self-winding module via a Perpetual rotor andoffers a power reserve of approximately 72 hours.
OYSTER BRACELET
This new version of the Cosmograph Daytona isfitted on a solid-link Oyster bracelet in 18 ct Everose gold with ceramic inserts and an Oysterlock safetyclasp to prevent accidental opening. The bracelet includes the Easylink rapid extension system, pa-tented by Rolex in 1996, that allows the wearer toeasily increase the bracelet length by approximately 5 mm for additional comfort.
SUPERLATIVE CHRONOMETER CERTIFICATION
Like all Rolex watches, the Cosmograph Daytona is covered by the Superlative Chronometer certi-fication redefined by Rolex in 2015. This exclusive designation testifies that each watch has success-fully undergone a series of tests conducted by Rolex in its own laboratories according to its own criteria, which exceed watchmaking norms and standards. The certification applies to the fullyassembled watch, after casing the movement, guar-anteeing superlative performance on the wrist in terms of precision, power reserve, waterproof-ness and self-winding. The precision of a Rolex Superlative Chronometer after casing is of the order of −2 /+2 seconds per day, or more than twice that required of an official chronometer.
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.
