This Oyster Perpetual Cosmograph Daytona in 18 ct Everose gold with a sundust, diamond-set dial and an Oysterflex bracelet, features a Black Cerachrom bezel with tachymetric scale.
This chronograph was designed to be the ultimate timing tool for endurance racing drivers. More than 50 years after its creation, the Cosmograph Daytona remains in a class of its own among sport chronographs and continues to transcend time.
A WATCHMAKING TECHNIQUE
The sunray finish creates delicate light reflections on many dials in the Oyster Perpetual collection. It is obtained using masterful brushing techniques that create grooves running outwards from the centre of the dial. Light is diffused consistently along each engraving, creating a characteristic subtle glow that moves depending on the position of the wrist.
Once the sunray finish has been completed, the dial colour is applied using Physical Vapour Deposition or electroplating. A light coat of varnish gives the dial its final look.
THE TACHYMETRIC SCALE
A key part of the model’s identity is the bezel moulded with a tachymetric scale for measuring average speeds of up to 400 miles or kilometres per hour. Blending of high technology with sleek aesthetics, the black bezel is reminiscent of the 1965 model that was fitted with a black Plexiglas bezel insert.
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. This extremely durable bezel also offers an exceptionally legible tachymetric scale, thanks to the deposition of a thin layer of platinum in the numerals and graduation 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.
18 CT EVEROSE GOLD
AN EXCLUSIVE PATENT
To preserve the beauty of its pink gold watches, Rolex created and patented an exclusive 18 ct pink gold alloy cast in its own foundry: Everose gold. Introduced in 2005, 18 ct Everose is used on all Rolex Oyster models in pink gold.
THE OYSTERFLEX BRACELET
HIGHLY RESISTANT AND DURABLE
The new Cosmograph Daytona is fitted with an Oysterflex bracelet, developed and patented by Rolex. 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 Oysterlock safety clasp and is equipped with the Rolex patented Easylink rapid extension system that allows the wearer to increase the bracelet length by approximately 5 mm, for additional comfort in any circumstance.
START, DRIVE, STOP
THE ULTIMATE RACING TOOL WATCH
The Daytona’s chronograph feature functions are activated by pushers that screw down like the winding crown when they are not in use, guaranteeing waterproofness to 100 metres. One press to start, stop or reset the chronograph produces a crisp, clear click that was perfected using the most advanced technology. Rolex watchmakers also perfected the mechanism to suit the ideal finger pressure on the pushers, and engineered it to provide an instantaneous and accurate start to the timing without sacrificing reliability.
The Cosmograph Daytona is equipped with calibre 4130, a self-winding mechanical chronograph movement developed and manufactured by Rolex. Its architecture incorporates far fewer components than a standard chronograph, thereby enhancing the movement’s reliability. Like all Rolex Perpetual movements, the 4130 is a certified Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. The chronograph movement features a Parachrom hairspring, offering greater resistance to shocks and to temperature variations.
