Abstract
A moon phase indicator mechanism, for a timepiece provided with a movement and a dial, the moon phase indicator mechanism including at least one moon disc, and at least one moon phase train driven by the timepiece movement, the moon phase train meshing with a moon phase wheel which carries the moon disc at least indirectly and in a fixed manner, the moon phase wheel taking the form of a toothed ring in order to move the moon disc with the moon phase train about an axis A.
Claims17
A moon phase indicator mechanism, for a timepiece provided with a movement and a dial, the moon phase indicator mechanism comprising:
- at least one moon disc,
- at least one moon phase train disposed underneath the dial and driven by the timepiece movement, the moon phase train meshing with a moon phase wheel taking the form of a toothed ring in order to move the moon disc at a periphery of the dial about an axis A arranged at the centre of the dial, with the moon phase train, and
- an intermediate part,
- wherein movement of the moon disc around the dial is to simulate moon phases, and
- wherein the moon phase wheel indirectly carries the moon disc with the intermediate part such that the moon disc is non-rotationally fixed to the intermediate part, the intermediate part mounted on the toothed ring, the intermediate part surrounding the dial and the movement.
