The rotating display member is integral in rotation with a snail cooperating with the beak of a striking rack included in a striking mechanism integrated in or juxtaposed with this display mechanism, to strike a numerical value characteristic of this magnitude, or respectively of this position. The display mechanism is more particularly a chronograph mechanism including a seconds snail integral with a main chronograph wheel, for counting the seconds and cooperating with a seconds rack, and a minute snail integral with a minute counter wheel for counting the minutes and cooperating with a minute rack, in order, after timing a duration, to strike the minutes and seconds of the timed duration.

A display mechanism for n moonphases for a timepiece, where n?3, includes a first wheel and pinion having a night-time background and a portion of lunar background and a second wheel and pinion superposed on the first, the second having a night-time background and moonphase profiles, with the first and second pivoting about one axis. The first wheel and pinion is driven at a constant velocity, and that the second can be driven in rotation at the same velocity and direction as the first during a moonphase display period during which a portion of lunar background of the first and a moonphase profile of the second corresponding to the moonphase to be displayed are superposed, revealing the moonphase. The second wheel and pinion is offset from the first by a repositioning angle during a transitional period between the current and following display periods, revealing the following moonphase.

Device for displaying phases of the moon with a fist display member (80) bearing a plurality of first images (81-86) at least partially representing the moon, a display zone, driving means (22, 23, 25, 40, 41, 43, 63, 71, 72, 61, 62) arranged to displace, by successive jumps, the first display member (80) relative to the display zone, to display a succession of representations of the moon. An original feature of the invention is that the periods of display of the first images are not all equal.

A wristwatch (an example of a timepiece) includes a small dial (an example of a dial) and a rotary disk (an example of a rotary member). The small dial includes a sun mark for displaying the state of the sun. The rotary disk covers the small dial and rotates in a 24-hour period. The rotary disk includes the sun state indicator that changes the visibility of the sun mark in accordance with the rotational position of the rotary disk. One of the small dial and the rotary member includes a plurality of numbers (an example of indexes) for indicating time. The other of the small dial and the rotary member includes a time indicator that indicates a number in accordance with the rotational position of the rotary disk.
