ABSTRACT:
The invention relates to a time display apparatus consisting of at least two partly transparent discs (A, B, C) which are arranged concentrically and axially displaced with respect to one another, with each of the discs (A, B, C) being rotationally driven about the central axle with separately preselectable period duration and being provided with a visible marking for the display of hours, minutes and seconds, with one freely rotating disc (D, E) which carries a graphical representation being concentrically arranged axially adjacent to at least one of the rotationally driven discs (C). The invention is based on the object of displaying not only the time by means of the time display apparatus, but also of enabling special optical effects. This is achieved in such a way that the rotationally driven disc (C) is provided with a (first) entrainment means (X.sub.1) on its side facing the freely rotatable disc, which means cooperates with a (first) actuating means (X.sub.2) arranged on the side of the freely rotatable disc (D) facing the rotationally driven disc (C).
