AN OBSESSION WITH PERFECTION
4130 CHRONOGRAPH
MOVEMENT
Inside the elegantly designed exterior, the Cosmograph Daytona is a masterpiece of watchmaking art. The 4130 chronograph calibre movement was conceived and assembled exclusively by Rolex in 2000 for the Cosmograph Daytona and incorporates just 290 components – far fewer than a standard chronograph – making it a much admired symphony of simplicity. It has a 72-hour power reserve (66 hours if the stopwatch is in use) and inside, the blue Parachrom hairspring - made from a unique alloy impervious to magnetic fields - gives it up to 10 times more resistance to shocks than conventional hairsprings.
