History of the Rolex Day-Date 228239

The Rolex Day-Date, famously nicknamed the “Presidential”, holds a prestigious place in horological history as Rolex’s flagship model, first introduced in 1956. It was the world’s first wristwatch to simultaneously display the day of the week spelled out in full alongside the date window—an innovation that quickly made it a favorite among world leaders, dignitaries, and influential figures.
