Similarly, it is not necessary that the disk of the months 3 is arranged as a ring, it can also be formed by a solid disk. Also, in both cases, the drive train 6 could cooperate with the disk of the months 3 with the aid of an external toothing or a disk axis instead of an internal toothing.

  • a calendar display device having the features mentioned above according to the present invention has the important advantage of offering, beside a global view of calendar data for a whole month, the ability to manually change the displayed month, like a calendar, offering the user the ability to consult at any time the calendar data of the month he wants.
  • a device normally also allows automatic indexing between the indications of the days of the week and the dates when changing the month display. This automatic indexing applies to normal years as well as leap years, making the device perpetual. Also, this automatic indexing can be achieved by several means, including a direct kinematic link between the month disk and the rotating disk, so particularly elegantly at the technical level.
  • the device has great flexibility because it can be declined in several variants depending on the technical or aesthetic requirements. These advantages are obtained without increasing the complexity, the volume occupied, or even the production cost of the device.
  • the device according to the present invention is ideally suited to be highlighted visually on the dial of the timepiece, thus contributing significantly to the aesthetics of such a timepiece.
