The Day-Date has been esteemed as a watch of nobility, prestige, and distinction since its debut in 1956. Making the watch even more deserving of its nickname is the President’s bracelet, which Rolex designed specifically for the 1956 launch of the Day-Date. This model has been worn by more presidents and prominent leaders and figures than any other watch. The Day-Date was also the first wristwatch to display the date and day of the week fully spelled out in a window on the dial. It is available in case diameters of 36 mm and 40 mm known as the Day-Date 36 and Day-Date 40, respectively. The Day-Date 40 is a new-generation model that is driven by another one Rolex’s new-generation developments, Calibre 3255 movement. In line with its reputation as a timepiece of status and exclusivity, the Day-Date is made only of precious metals: 18 carat gold or platinum.
