Rolex is introducing three new versions of its Oyster Perpetual Cosmograph Daytona in 18 ct yellow, white or Everose gold. These versions are fitted on the innovative Oysterﬂex bracelet in elastomer reinforced with a metal blade, and are equipped with a monobloc Cerachrom bezel, patented by Rolex, in black ceramic. This latest evolution is a blend of high technology and sleek aesthetics, and pays tribute to the heritage of this legendary chronograph. The black bezel is reminiscent of the 1965 model that was fitted with a black Plexiglas bezel insert.
Like all Rolex watches, these new Cosmograph Daytona versions carry the Superlative Chronometer certification redefined by Rolex in 2015, which ensures singular performance on the wrist.
The robust chronograph is engaged by a mechanism with a column wheel and vertical clutch, allowing an instantaneous and extremely precise start. The oscillator, the true heart of the watch, has a blue Parachrom hairspring patented and manufactured by Rolex in an exclusive alloy. Insensitive to magnetic fields, the Parachrom hairspring offers great stability in the face of temperature variations and remains up to 10 times more precise than a traditional hairspring in case of shocks. A Rolex overcoil ensures its regularity in any position. Calibre 4130 is equipped with a self-winding module featuring a Perpetual rotor and boasts a power reserve of approximately 72 hours.
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.
