Mechanism for displaying periods of an annual cycle of a timepiece

A mechanism for displaying the periods of an annual cycle for a timepiece driven by a running train of a horological movement, wherein the mechanism for displaying the periods of an annual cycle comprises:

• an indicator indicating the periods of an annual cycle;
• and
• an annual cycle train configured to be driven by said running train of the horological movement, and to rotate the indicator of the periods of an annual cycle;
• wherein the annual cycle train forms a gear train between the running train and the indicator of the periods of an annual cycle including at most four gearings, and
• wherein the ratio of the gear train of the annual cycle train has the prime number 17, 11 or 5 in the numerator and 2 in the denominator.
