The miracle of midnight An ideal of precision
When midnight strikes, the day and date simultaneously change in their respective windows on the dial. This watchmaking feat, the “miracle of midnight”, relies on a disc mechanism. It is the fruit of numerous years of research: from 1950 to 1955 Rolex registered four patents for timepieces featuring an indication of day and date.
Today, the Day-Date is equipped with calibre 3255, a movement entirely developed and manufactured by Rolex for a superlative level of performance.
