Displaying device for movement e.g. mechanical type movement, of timepiece to display date of month, has tenths representing display driven by tenths displaying mechanism, and units representing display driven by units displaying mechanism
The device has a cam for displaying tenths of a day of a month, and another cam for displaying units of the day of the month, where the cams are fixed on a crown of a timepiece movement. Figure retrograde displays (1, 3) represent tenths of the day of the month, and other figure retrograde displays (2, 4) represents the units of the day of the month. The former retrograde displays are driven by a tenths displaying retrograde mechanism from the former cam, and the latter retrograde displays are driven by a unit displaying retrograde mechanism from the latter cam. An independent claim is also included for a timepiece movement comprising a display device.
