Abstract
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.
