The Rolex Day-Date, introduced in 1956, was the first wristwatch to display the date and day of the week spelled out in full in a window on the dial. It is exclusively made of precious metals, primarily 18k gold or platinum. The Day-Date is often associated with influential figures and has earned the nickname 'The President’s Watch.'
