Rolex Oyster Perpetual Datejust New Versions for Ladies
Launched in 1945, the Oyster Perpetual Datejust was the first Rolex watch to display the date in an aperture on the dial. Today it is the front-runner of the Rolex Oyster collection and is available in a wide variety of versions. At midnight, the date changes instantly.
A new range of dials was brought out in 2009 combining a spirit of classic refinement and creative reverie.
Self-winding, equipped with a Perpetual rotor and certified by the Swiss Official Chronometer Testing Institute (COSC), the Oyster Perpetual Datejust is guaranteed waterproof to a depth of 100 metres (330 feet). It features a sapphire crystal with a Cyclops lens.
