The Rolex Oyster Perpetual Datejust revolutionized the calendar display of watches. Traditional calendar watches have a calendar circle on the outer ring, and the date is indicated by a pointer. Rolex set a calendar window at 3 o'clock on the Datejust, and the date is displayed on the calendar disk. This design was later widely used in the watchmaking industry. In 1953, Rolex added a small window convex lens to the mirror to facilitate calendar reading. In 1956, the instantaneous calendar was launched. In 1977, a new function was introduced, which allows the date to be adjusted quickly and reliably by rotating the winding crown clockwise or counterclockwise. This function was also introduced in the Datejust models with medium or large movements; this function was introduced in the Datejust models with small movements in 1983.
The Oyster case of the Rolex Oyster Perpetual Datejust is guaranteed to be waterproof to 100 meters (330 feet) and is a model of sturdiness and elegance.
