Rolex is introducing updated versions of its quintessential Oyster Perpetual model in 31 and 36 mm featuring exclusive new dials. The Oyster Perpetual – the purest expression of the Oyster concept and having no other function than a clear, accurate time display – comprises the renowned Rolex waterproof Oyster case and the self-winding Rolex Perpetual movement famed for its precision and reliability. The oscillator, the true heart of the watch, has a blue Parachrom hairspring patented and manufactured by Rolex

Insensitive to magnetic fields, the Parachrom hairspring offers great stability when exposed to temperature variations and remains up to 10 times more precise in case of shocks than a traditional hairspring. The Oyster Perpetual watches are paired with a solid-link Oyster bracelet in 904L steel which is very secure and comfortable to wear. The 36 mm Oyster Perpetual is equipped with COSC calibre 3130, a self-winding mechanical movement, and the smaller version is equipped with COSC calibre 2231.
