Disclosed is a display mechanism for a timepiece, including a frame, an aperture which is fixed relative to the frame and a first and a second display disc each bearing indications, characterized in that it makes it possible to display the indications of the first and second discs alternately through the aperture. The invention also relates to a timepiece movement including such a mechanism, and to a timepiece such as a wrist watch, a pocket watch, a clock or a miniature clock including such a timepiece movement.

A timepiece display device including a first display element and a second display element superimposed above a fixed part including a main bearing surface, this second display element is subjected to opposing forces exerted, on the one hand by lower return means which tend to bring the second display element closer to the first display element, and, on the other hand, by upper return mechanism which tends to move the second display element away from the first display element without contact between them or else by mechanical spacing device which includes a bearing surface providing a stop bearing function on a stop surface of the second display element, to limit the travel from the second display element to the first display element.
