Timeless Distinction The Datejust 36 has long been a symbol of Rolexs pioneering spirit. Introduced in 1945, it was the first wristwatch to feature an automatically changing date display, combining technical innovation with enduring style. Classic Aesthetics This reference, from 2004, features a 36mm case in Oystersteel and yellow gold, with a silver gem-set dial and fluted bezel. Powered by the calibre 3135 automatic movement, it offers a 48-hour power reserve and is paired with an Oyster bracelet secured by an Oysterclasp and Easylink extension.
