The Day-Date. A horological miracle. The first self-winding waterproof wristwatch to display the date and day of the week spelt out in full. At midnight, something is achieved that has come to be known as “the miracle of midnight”, when both the day and date change simultaneously. Mother-of-pearl dial with diamond hour markers and bezel set with trapeze-cut diamonds. 18ct white gold, 36mm, calibre 3255.
