PERFECT ALCHEMY OF FORM AND FUNCTION
Efficient, precise, legible, robust, reliable, waterproof and self-winding, the Cosmograph Daytona is also comfortable, elegant and timeless. Judging by the success and outstanding reputation worldwide of this perfect alchemy of form and function, it is considered in many respects to be the ultimate chronograph.
START, STOP, RESET
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 meters. 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.
PERPETUAL CALIBER 4130
Caliber 4130’s performance stems particularly from the use of a vertical – instead of lateral – clutch to activate the chronograph. This solution functions on the principle of two discs, one above the other, which work together by direct friction contact and offer significant advantages – extremely precise starting and stopping of the perfectly smooth running chronograph seconds hand as soon as the pusher is pressed; and the capacity of the chronograph to function for long periods of time with no negative impact on the precision of the watch.
MONOBLOC CERACHROM BEZEL
The monobloc Cerachrom bezel in high-tech ceramic offers a number of advantages: it is corrosion resistant, virtually scratchproof and the color 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 Vapor 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.
