This device for displaying time periods comprises a display element (A), an indicator component (1), a drive component (3) for driving the indicator component (1), an instantaneous-jump cam (6) engaged with the drive component (3), a drive mobile (5) for driving the cam (6) and correction means (4) for coming into direct engagement with the indicator component (1). A one-way connection device (3b, 11, 12) connects the drive mobile (5) to the cam (6). The drive component (3) is engaged with the cam (6) by elastic return means (3d) and guidance means (3b) defining a degree of freedom of the drive component (3) in order to allow the indicator component (1) to move the drive component (3) against the elastic return means (3d) when the latter occupies a position interfering with the movement of the indicator component (1) by the correction means (4).
A device for displaying determined time periods comprising a display element (A) for displaying said time periods, an indicator component (1) mounted so as to be able to move relative to said display element (A), a drive component (3) furnished with a drive finger (3a) for driving the indicator component (1), a cam (6) comprising a progressive winding phase and an instantaneous unwinding phase of a spring (9), this cam (6) being engaged with said drive component (3), a drive mobile (5) for driving said cam (6) in a cycle corresponding to that of said time periods and correction means (4) for coming into direct engagement with said indicator component (1), characterized in that a one-way connection device (3b, 11, 12) connects said drive mobile (5) to said cam (6).
