Introduced in 1956, the Oyster Perpetual Day-Date was the first calendar watch to display the fully spelled day of the week and the date. This model, which exemplifies Rolex's commitment to excellence, has rapidly gained popularity among influential individuals. Its Oyster case, guaranteed to be watertight to a depth of 100 meters or 330 feet, exemplifies both durability and elegance. The 18K yellow gold fluted bezel surrounds a neat white dial with applied yellow gold Roman numerals. The sapphire crystal's Cyclops lens at 3 o'clock makes it easy to read the date. In addition, the Oyster Perpetual Day-Date is equipped with a Rolex self-winding movement.

English calendarThe caliber 3155, introduced in 1988, is a self-winding mechanical movement entirely developed and manufactured by Rolex. It features a day and date calendar disc mechanism. Like all Rolex Perpetual movements, the 3155 is a certified Swiss chronometer, a designation reserved for high-precision watches that have successfully passed the Swiss Official Chronometer Testing Institute (COSC) tests. In common with all Oyster watch movements, its architecture makes it singularly reliable. This mechanism oscillates at a frequency of 28,800 vhp (4Hz)
Initially presented in 1956, the Day-Date was a world-first watch to indicate the day of the week spelled out in full. The collection comprises precious metals and is available in various options and bracelet designs, including the well-known President bracelet.
