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 a new-generation movement, calibre 3255, entirely developed and manufactured by Rolex for a superlative level of performance.
