Abstract (en)

A timepiece is described that includes a mechanical power system having a mainspring and housed in a barrel that is powered by the mechanical energy provided by the mainspring. The timepiece also includes a main wheel train engaged with the barrel and including an assembly of wheels meshed to each other for transmitting a torque output of the mainspring for driving time indicating hands. The timepiece also includes an electric motor engaged with a predetermined wheel of the main wheel train through an electric motor transmission mechanism, so as to provide an additional controllable torque output to main wheel train for driving the time indicating hands, thereby a total torque that drives the timepiece includes the torque provided by the mainspring and the additional controllable torque provided by the electric motor.
