Moon phase display mechanism of a timepiece

A moon phase display mechanism for a timepiece capable of being driven by a horological movement, an operation thereof depends on a time division, said moon phase display mechanism comprising:

• a moon phase indicator carrying at least one representation of the moon;
• a jumping drive mechanism of the moon phase indicator capable of being driven by said horological movement and of driving, in jumps, the moon phase indicator;
• wherein the jumping drive mechanism is configured to rotate said moon phase indicator by n increments per day, n being greater than 1, each increment rotating the moon phase indicator by an angle α corresponding to an angle of rotation of a daily pitch divided by a number n of increments,
• wherein the jumping drive mechanism comprises:
• a cam comprising an upper area forming a driving finger-piece, said cam being capable of being driven by the horological movement;
• a phase lever mounted such that it pivots about a pivot axis, said phase lever comprising, at one of the ends thereof, a feeler sensing the movements of the cam and comprising, at the other end thereof, a correction beak driving said moon phase indicator upon each passage of the upper area of the cam;
• a phase-driving intermediate wheel set rotated by the phase lever, said phase-driving intermediate wheel set meshing with the moon phase indicator;
• and
• a jumper cooperating with the phase-driving intermediate wheel set for indexing and holding said phase-driving intermediate wheel set in position between each increment,
• wherein said phase-driving intermediate wheel set comprises a phase-driving star-wheel configured to be rotated by the phase lever, and a phase-driving pinion integral with the phase-driving star-wheel such that it rotates therewith, said phase-driving pinion being meshed with a phase wheel comprised in the moon phase indicator.
