Abstract

The timepiece comprises a movement (1) that rotatably drives at least an hours-hand before a dial (5). The dial (5) is formed with at least one display aperture (g1). Signs (s1, s2), which respectively represents the numbers of the hours shown by the hours-hand when the latter is in the same angular position as the display aperture (g1) a.m. and p.m., are arranged on a disc (6) which is located beneath the dial (5) and which is driven by a mechanism (7) that is connected to the movement (1). This mechanism (7) is so designed that the first and second signs (s1, s2) appear in the display aperture (g1), one a.m. (ante meridiem), the other p.m. (post meridiem). To simplify its construction, the mechanism (7) is so designed that the disc (6) will always be rotated in the same direction.
