Abstract (en)

[origin: WO2011045233A1] The invention relates to an energy source for a repeater striking mechanism for a timepiece, including a resilient member arranged so as to generate a torque, winding means (24, 54) for said resilient member, and a kinematic linking means (46) for applying said torque to the members of the striking mechanism so as to provide striking. According to the invention, the resilient member comprises two springs (38, 40) wound in the same direction in concentric spirals, stacked and arranged so as to apply said torque to the kinematic linking means (46).
