Rolex's signature day-disc display is exclusive to its Day-Date collection.
Unveiled in 1956, it has been available in 26 languages since 1973. Within its curvature, the new day appears at midnight, in perfect synchronicity with the date disc, with all seven days appearing in full in the window. Unabbreviated. It might seem a small detail, but it reflects their unrelenting will to do things completely, never cutting corners.
