• a mechanism (4) for managing a duration during which the periodic events are displayed by the periodic events indicator member (2), this management mechanism (4) comprising:
• a cam (8) for managing a duration during which the periodic events are displayed, which cam is arranged such that it controls the change from the indication of a periodic event to the indication of a subsequent periodic event by the periodic events indicator member (2);
• periodic drive means (10) for driving the management cam (8), and
• a member (6) disposed between the management cam (8) and the periodic events indicator member (2) and arranged such that it drives the periodic events indicator member (2) during a change in event,
• wherein the management cam (8) is concentric with the periodic drive means (10) which meshes with a sun wheel (34) which meshes with the periodic events indicator member (2).
