Enduring Legacy The Rolex Datejust is a cornerstone of the brands heritage, introduced in 1945 as the first self-winding chronometer wristwatch to display the date in a window at 3 oclock. Its timeless design and technical innovation have made it one of the most recognisable and enduring models in the Rolex collection. Refined Versatility This 2011 reference 116200 features a 36mm Oystersteel case and a silver dial framed by a smooth domed bezel. It is powered by the calibre 3135 automatic movement, offering a 48-hour power reserve. The Oyster bracelet is fitted with an Easylink extension system and Oysterclasp, delivering comfort and adaptability in a classic silhouette.
