Rolex Day Date
Launched in 1956, the Day-Date made its debut as the first waterproof and self-winding chronometer wristwatch to offer a modern calendar with an instantaneous day display, spelt out in full in a window on the dial, in addition to the date. The exceptional precision, reliability, legibility and presence of this prestigious model has made it the ultimate status watch.
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.
