At Baselworld 2017 Rolex is introduced three new versions of its Oyster Perpetual Cosmograph Daytona in 18 ct yellow, white or Everose gold. These versions are fitted on the innovative Oysterfiex bracelet in elastomer reinforced with a metal blade, and are equipped with a monobloc Cerachrom bezel, patented by Rolex, in black ceramic.
CERACHROM BEZEL AND MEASURING SPEED
Created 1963, the Oyster Perpetual Cosmograph Daytona is a watch born to race. It has established an extraordinary track record in the world of motor sport thanks to its reliability and performance. Known simply as the “Daytona”, it has risen to the rank of an icon as one of the best known chronographs in the world. A key part of the model’s identity is the bezel engraved with a tachymetric scale for measuring average speeds of up to 400 units of distance – miles or kilometres – per hour.
This extremely durable bezel also offers an exceptionally legible tachymetric scale, thanks to the deposition of a thin layer of 18 ct gold or platinum in the numerals and graduations via a PVD (Physical Vapour Deposition) process. The monobloc Cerachrom bezel is made in a single piece and holds the crystal firmly in place on the middle case, ensuring waterproofness.
The monobloc Cerachrom bezel in high-tech ceramic offers a number of advantages: it is corrosion resistant, virtually scratchproof and the colour is unaffected by UV rays.
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, proportion and elegance. Its characteristically shaped middle case is crafted from a solid block of 18 ct gold. Its fluted case back is hermetically screwed down with a special tool that allows only Rolex watchmakers to access the movement. The winding crown – fitted with the Triplock triple water-proofness system – as well as the chronograph pushers screw down securely against the case. Its crown guard is an integral part of the middlecase. 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 chronograph movement entirely developed and manufactured by Rolex. Its architecture, a composite of Rolex technology, was completely re-engineered: the number of components for the chronograph function was reduced significantly, thereby enhancing the movement’s reliability.
The robust chronograph is engaged by a mechanism with a column wheel and vertical clutch, allowing an instantaneous and extremely precise start. The oscillator, the true heart of the watch, has a blue Parachrom hairspring patented and manufactured by Rolex in an exclusive alloy. A Rolex overcoil ensures its regularity in any position. Calibre 4130 is equipped with a self-winding module featuring a Perpetual rotor and boasts a power reserve of approximately 72 hours.
OYSTERFLEX BRACELET AND SAFETY CLASP
The new Cosmograph Daytona versions are fitted on an Oysterflex bracelet, developed and patented by Rolex. This technical bracelet combines in a singular way the robustness and reliability of a metal bracelet with the flexibility, comfort and aesthetics of an elastomer strap. At its core lies a superelastic metal blade overmoulded with high-performance black elastomer, a material that is particularly resistant to environmental effects and very durable.
The Oysterflex bracelet is also fitted with an 18 ct yellow, white or Everose gold Oysterlock safety clasp that prevents accidental opening. It is equipped with the ingenious Rolex-patented Easylink rapid extension system that allows the wearer to easily increase the bracelet length by approximately 5 mm, for additional comfort in any circumstance.
SUPERLATIVE CHRONOMETER CERTIFICATION
Like all Rolex watches, the Cosmograph Daytona is covered by the Superlative Chronometer certification redefined by Rolex in 2015. This exclusive designation testifies that the watch has successfully 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 fully assembled watch, after casing the movement, guaranteeing its superlative performance on the wrist in terms of precision, power reserve, waterproofness 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 new Rolex Cosmograph Daytona is available in 18 ct yellow, white or Everose gold with different dial combinations. Discover all models in the gallery below:
