Any day can leave a lasting mark on our lives and set the stage for new aspirations. Since its creation in 1945, the Datejust has continued to reinvent itself while symbolizing Rolex’s definition of classic elegance. A milestone in watchmaking history, it was the first selfwinding waterproof chronometer wristwatch to feature a window displaying the date. Magnified by the Cyclops lens, these numbers are a reminder that though 24 hours mark a day, it’s on us to make those a date to remember.
