Retrograde €“ a retrograde display does not display the function in a circular fashion, as we are used to seeing. Rather, it sets out the functions in a linear manner. Instead of the hands going round in a circle, they travel along an arc, and when they get to the end, they jump back to the beginning. Jumping hour €“ Instead of a hand continuing to move, a €œjumping display€ uses numerals seen through an aperture, which instantly change on the hour . The circular motion of hands has been adopted by our societies as the most €œnatural€ way to convey the passing of time, no doubt because it recalls the rotation of the planets and the apparent movement of the sun, our first timekeeper. There are, however, other ways to indicate time, such as a €œjumping display€, typically used to show the hour. It exchanges the hand for a disc inscribed with the hour numerals, visually similar to a calendar aperture. However, unlike certain calendars, each new indication is instantaneous. On each hour, the mechanism causes the disc to make one jump forward, and then blocks it in this position until the following hour. 100% original and in great condition.
