Abstract
The invention concerns a mechanical device (100) for the sequential control of at least two levers for a timepiece mechanism, controlling a first lever (1) and a second (2) lever cooperating with a contact surface (10) in accordance with a sequence wherein each changes from a first torque consumption level (11; 21) to a second, higher level (12; 22) during an increasing phase (14; 24) in which it stores torque, then from said second level (12; 22) to said first level (11; 21) during a decreasing phase (15; 25) in which it transmits energy.The device is wherein it includes delaying means (4) creating, during the decreasing phase (15) of said first lever (1), a stabilizing stage at a third, intermediate level (13) between said first (11) and second (12) levels.The invention also concerns a timepiece incorporating a device (100) of this type.
