In 1956, the Oyster Perpetual Day-Date made its debut. Available only in 18 ct gold or platinum, it was the first wristwatch to display the date and day of the week spelt out in full in a window on the dial. With the President bracelet, originally created specially for it, the Day-Date continues to be the watch par excellence of influential people.
The Day-Date 40 is equipped with a new-generation movement, calibre 3255, entirely developed and manufactured by Rolex for a superlative level of performance. This self-winding mechanical movement is at the forefront of the art of watchmaking. A consummate demonstration of Rolex technology, with 14 patents, it offers fundamental gains in terms of precision, power reserve, resistance to shocks and magnetism, ease of use and reliability.
