01 ROLEX OYSTER PERPETUAL COSMOGRAPH DAYTONA
Rolex, the official timekeeper of Formula One, marks high quality performance with the Oyster Perpetual Cosmograph Daytona. Bestowed with a Superlative Chronometer certification, this 18K yellow gold watch is precise to the order of −2/+2 seconds per day after casing, more than twice the requirements of an official chronometer. The impressive movement is the Calibre 4130 mechanical chronograph, equipped with a self-winding module featuring a Perpetual rotor and patented Parachrom hairspring in the oscillator, making it virtually immune to shocks and temperature fluctuations. Atop the 40mm case is a patented monobloc Cerachrom bezel engraved with a highly legible tachymetric scale marked with a thin layer of 18K gold. The Cosmograph Daytona remains firmly attached to the wrist at high speeds thanks to the Oysterflex bracelet fitted with an 18K yellow gold Oysterlock safety clasp that prevents accidental opening.
