Timepiece movement and timepiece including such a movement

A timepiece movement comprising:

• a mechanical energy source;
• a first regulating organ and a first escapement linked by a first gear train to the energy source, the first gear train, the first escapement and the first regulating organ defining a first ensemble;
• a second regulating organ and a second escapement linked by a second gear train to the energy source, the second gear train, the second escapement and the second regulating organ defining a second ensemble;
• at least one differential gear arranged to provide a kinematic link firstly between the first ensemble and the energy source and secondly between the second ensemble and the energy source;
• a first spring organ provided between the at least one differential gear and the first escapement and arranged to exert torque on a first output of the at least one differential gear;
• a first device configured to re-charge the first spring organ;
• a second spring organ provided between the at least one differential gear and the second escapement and arranged to apply torque to a second output of the at least one differential gear;
• and
• a second device configured to re-charge the second spring organ.
