Timeless Simplicity The Oyster Perpetual 36 continues the legacy of Rolexs original waterproof wristwatch. With its precision engineering and understated design, it remains a cornerstone of the Oyster collection. Confident Character This 2015 model features a 36mm Oystersteel case with a domed bezel and distinctive white grape dial. It is powered by the calibre 3130 automatic movement with a 48-hour power reserve and is fitted with an Oyster bracelet and Oysterclasp. A bold yet refined expression of everyday Rolex style.
