A horological display mechanism (100) for displaying variables on separate unit display supports (10), each enclosing a display indicator (901; 902) which is a first display (901) capable of moving in translation, or a second display (902) capable of moving in rotation, all of these unit supports (10) include indicators (901; 902) of the same kind, which are either first displays (901) for displaying a first variable, or second displays (902) for displaying a second variable, or both first displays (901) and second displays (902), all visible to the user, the display mechanism (100) includes a control mechanism (300) arranged to drive wheels or rod systems for driving the different display wheel sets and includes a first carrier (111) for driving, by itself, all of the first displays (901), and/or a second carrier (112) for driving, by itself, all of said second displays (902).

A Moon phase and Earth phase display device (100) for a horological movement, which device includes a display (110) including a plurality of graphical representations (120) symbolising respectively different successive phases of a celestial body, a dial (130) provided with two apertures (131) arranged so as to concomitantly display two diametrically opposed graphical representations (120), one of which symbolises a Moon phase and the other of which symbolises an Earth phase, and a drive mechanism (140) configured to drive the display (110) in sequential movement.

There are provided an information display mechanism, a timepiece movement, and a timepiece each capable of achieving a reduction in space. The information display mechanism includes a display wheel which has a plurality of inner teeth, on which information is displayed, and which has a ring-like shape, a driving wheel having a plurality of tooth parts configured to mesh with the inner teeth, and a drive section configured to rotate the driving wheel. The driving wheel is configured to rotate in a state in which the tooth parts and the inner teeth mesh with each other to thereby rotate the display wheel. The display wheel is provided with a regulatory protruding part configured to regulate mesh with the driving wheel. The drive section is configured to rotate the driving wheel in a first direction and a second direction opposite to the first direction.
