ABSTRACT:
A clock with a movable moon display having an improved moon dial in which a moon replica plate is associated integrally with the moon dial in spaced recessed relation to a round opening in the dial so that the moon replica takes on a shadowed illusion of depth while moving bodily with the dial transit of the display. This shadowed illusion can be disirably emphasized or enhanced by the provision within the clock housing of a source of illumination impinging on the display.
