History of the Datejust and the Jubilee Bracelet... First introduced in 1945 as a means to commemorate the company's 40th anniversary, the Datejust is one of Rolex's oldest collections of watches that still remain in production today. While a date display has become completely standard on most contemporary timepieces, the Rolex Datejust was the world's very first self-winding wristwatch to feature a date window that would automatically change over at midnight. The Rolex Jubilee bracelet was first launched in 1945. As the name suggests, it was released to celebrate a jubilee. More specifically, in celebration of Rolex's 40th anniversary. Originally, the Jubilee bracelet was specifically designed for the Datejust line, but as you know, that is not the case today.
