Rolex Day-Date, self-winding chronometer wristwatch notable for becoming the first wristwatch with a day-date function. Nicknamed the "Rolex President watch", the Day-Date has long been synonymous with prestige, power, and exclusivity. In 1948, the Chairman of Rolex presented President Eisenhower with an 18kt yellow gold Datejust watch, one of the company's exclusive watches, to celebrate the Allied victory over the Nazis in World War II. However, in 1956, Eisenhower's watch needed a new bracelet. The new bracelet with a concealed clasp was nicknamed the "President's bracelet".
