Patent ID: 8711659

Claim:
A mechanical device for the sequential control of at least a first lever and a second lever of a timepiece mechanism, the first lever and the second lever being arranged for respectively controlling the movement of a first wheel set and a second wheel set, against elastic return means, to make two movements that are partially superposed, the control device including first means for winding the first wheel set and second means for winding the second wheel set, the control device being arranged to release the first wheel set and the second wheel set in succession and not simultaneously, wherein the first winding means includes means delaying the time between the winding and the release of the movement of the first wheel set, arranged for keeping potential energy accumulated in the mechanism for manoeuvring the first wheel set for a determined time period, so as to keep the first wheel set wound for the determined time period until the release thereof, and also wherein the first winding means includes means for transmitting motor means, comprised in the timepiece device or the control device, to a contact surface including a first path, for controlling the first lever, and on which is arranged at least one delay surface forming the delaying means.
