The Rolex Cosmograph Daytona, one of the most iconic watches of all time, is also available in yellow Rolesor under the reference 116503.
Rolesor – a marriage between steel and gold
Rolesor, the combination of gold and steel on a Rolex watch, has been a signature feature of the brand since 1933, when the name was registered. It is an auspicious meeting of two metals: one, noble and precious, attractive for its lustre and stability; the other, highly resistant, known for its strength and reliability. All of these qualities perfectly mirror the elegance and performance that come together in a Rolex watch. The yellow Rolesor concept is simple: the bezel, the winding crown, as well as the centre bracelet links are made of 18 ct yellow gold; the middle case and the outer links of the bracelet are made of 904L steel. Introduced on the Datejust in 1948, Rolesor contributed largely to the legendary status of this wristwatch.
The Oyster case – symbol of waterproofness
A paragon of robustness and reliability, the Oyster case of the Cosmograph Daytona Ref. 116503 is guaranteed waterproof to a depth of 100 metres (330 feet). The middle case is crafted from a solid piece of 18 ct yellow gold. The case back, edged with fine fluting, 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 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. The waterproof Oyster case provides optimum protection for the Cosmograph Daytona’s high-precision movement.
Perpetual calibre 4130
The Cosmograph Daytona Ref. 116503 is equipped with calibre 4130, a self-winding mechanical chronograph movement developed and manufactured by Rolex. The chronograph function has a reduced number of components, thereby 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.
Within this consummate demonstration of technology lies a blue Parachrom hairspring, manufactured by Rolex in an exclusive paramagnetic alloy that makes it up to 10 times more precise than a traditional hairspring in case of shocks. The blue Parachrom hairspring is equipped with a Rolex overcoil, ensuring its regularity in any position.
Calibre 4130 is equipped with a self-winding module via a Perpetual rotor and offers a power reserve of approximately 72 hours.
Start, drive, stop
The Daytona’s chronograph 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.
Cosmograph Daytona – Superlative Chronometer
Like all Rolex watches, each Cosmograph Daytona is certified as a Superlative Chronometer. This exclusive designation attests that it has successfully undergone a series of tests conducted by Rolex in its own laboratories and according to its own criteria, which exceed watchmaking norms and standards. These tests are carried out on the fully assembled watch, in order to guarantee its superlative performance on the wrist.
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.
