Abstract
The timepiece calendar system (200) includes a date mobile (4) which is displaceable step by step relative to a frame (199), a first drive finger (21) for driving the date mobile (4). a first tooth (51) for driving the date mobile (4), the first tooth (51) being mounted on the date mobile (4) so as to be displaceable between a deactivated, or retracted, position and an activated, or drive, position, an activation system (6, 7) for activating the first tooth (51); the first drive finger (21) and the first tooth (51) being arranged such that a single action of the first drive finger (21) on the first tooth (51) can displace the date mobile (4) through N steps, N being an integer such that N>1, notably N=2 or N=3.
Claims20
A timepiece calendar system, the system comprising:
- a date mobile which is displaceable step by step relative to a frame;
- a first drive finger for driving the date mobile;
- a first tooth for driving the date mobile, the first tooth being mounted on the date mobile so as to be displaceable between a deactivated, or retracted, position and an activated, or drive, position;
- an activation system for activating the first tooth;
- the first drive finger and the first tooth being arranged so that the first drive finger acting on the activated first tooth can displace the date mobile through N steps, wherein N is an integer and N>1.
