A timepiece includes: a central pivot; a central disk rotatable in a clockwise or counterclockwise direction around the central pivot; a stationary 24-hour scale arranged concentric to the central pivot; a sun mark; a large moon disk, the large moon disk being rotatably drivable in the counterclockwise direction at a rate of one revolution per synodic month; a moon view aperture in the large moon disk; and a small moon disk mounted at the large moon disk so as to be rotatable around a moon pivot parallel to the central pivot, the small moon disk carrying a plurality of dark circular areas. The dark circular areas are movable successively into registration with the moon view aperture and successively out of registration with the moon view aperture by the rotational movement of the small moon disk.
