Mechanism for displaying periods of an annual cycle of a timepiece

A mechanism for displaying periods of an annual cycle for a timepiece capable of being driven by being dragged by a running train of a horological movement, characterised in that the mechanism for displaying the periods of an annual cycle includes:

• an indicator indicating the periods of the annual cycle;
• an annual cycle train capable of being driven by said running train of the horological movement, and of rotating the indicator of the periods of the annual cycle;
• wherein the annual cycle train forms a gear train configured to have a ratio of 1:365.2 or a ratio that is a multiple of 1:365.2 between the running train and the indicator of the periods of the annual cycle, and
• wherein the annual cycle train includes:
• a first intermediate wheel set including a first intermediate wheel set wheel with 83 teeth and a first intermediate wheel set pinion with 8 teeth;
• a second intermediate wheel set including a second intermediate wheel set wheel with 99 teeth and a second intermediate wheel set pinion with 15 teeth;
• a third intermediate wheel set including a third intermediate wheel set wheel with 32 teeth and a third intermediate wheel set pinion with 15 teeth.

A horological movement including a running train and mechanism for displaying periods of an annual cycle, the mechanism being for displaying the periods of the annual cycle for a timepiece, capable of being driven by being dragged by a running train of a horological movement, and characterised in that the mechanism for displaying the periods of an annual cycle includes:

• an indicator indicating the periods of the annual cycle;
• an annual cycle train capable of being driven by said running train of the horological movement, and of rotating the indicator of the periods of the annual cycle;
• wherein the annual cycle train forms a gear train configured to have a ratio of 1:365.2 or a ratio that is a multiple of 1:365.2 between the running train and the indicator of the periods of the annual cycle,
• wherein the annual cycle train being directly meshed with the running train,
• wherein the running train includes an hour wheel carrying out one revolution in twelve hours, the annual cycle train being directly meshed with the hour wheel, and
• wherein the hour wheel has 20 teeth and wherein the indicator of the periods of the annual cycle is rotated by an annual cycle wheel with 100 teeth;
• the gear train of the annual cycle train having the following ratios:
• 83/20*99/8*32/15*100/15.
