The Rolex Oyster Perpetual Datejust is a certified, self-winding chronometer wristwatch manufactured by Rolex. When it was launched in 1945, the Datejust was the first self-winding chronometer wristwatch to indicate the date in a window on the dial. Today, it exists in a variety of sizes from 28mm to 41mm, in stainless steel, two-tone gold, and solid gold versions. For admirers of Rolex, a Rolex Datejust embodies the quintessential style of the brand. Timeless and elegant, anyone can find the perfect Rolex Datejust for his own collection, with both women and men's models available in a range of colourways.
