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.
