  • the annual cycle wheel 112 is a wheel having 50 teeth meshed with a 24-hour wheel having 10 teeth instead of 20 teeth as described previously.
  • the reports are preserved.
  • Such a mechanism for displaying the periods of an annual cycle is perfectly suited to mechanical watch movements with or without a date, to electronic or electromechanical watch movements, due to the fact that the mechanism for displaying the periods of an annual cycle annual is dragging and does not generate peaks in energy consumption on hourly gear 10.
  • the invention also relates to a clock movement 1 comprising a mechanism for displaying the periods of an annual cycle 100 according to the invention.
  • the mechanism for displaying the periods of an annual cycle according to the invention may also include ad hoc means making it possible to carry out a retrograde display of the periods of an annual cycle.

  • the invention also relates to a timepiece 200, such as a wristwatch, comprising a timepiece movement 1 according to the invention housed in a watch case 210.
