A timepiece striking mechanism including a mechanism for controlling a hammer arranged to strike a resonant component in an impact position, and movable within a working zone between a recoil and rest position and this impact position, this mechanism includes a device for limiting recoil of the hammer after impact, formed either by eddy current braking means arranged to brake the hammer when it enters a back zone, connected and contiguous to the working zone and opposite the impact position, and/or by mechanical friction and/or elastic return means integral with the hammer or an anchor-piece integral with the hammer, and arranged for friction and/or abutting engagement with a moving braking component or a surface of a fixed part of the striking mechanism.
A timepiece striking mechanism comprising a fixed part and a control mechanism arranged to directly or indirectly control the motion of at least one hammer including a striking area arranged to strike at least one resonant component or a gong or a disc-gong in a front impact position, said at least one hammer being movable within a working zone between a recoil and rest back position and said impact position, wherein said mechanism is arranged to limit the recoil of each said hammer by braking said hammer after impact, said hammer or an anchor-piece integral with said hammer having a first surface which, in a first alternative, is arranged to engage with at least one stator or at least one pole piece in a back zone, connected and contiguous to said working zone in said recoil and rest position and extending opposite said impact position with respect to said recoil and rest position, in order to brake said first surface by eddy currents or magnetic repulsion when said first surface enters said back zone, or, in a second alternative, is arranged for magnetic drive engagement with at least one moving component, comprised in said striking mechanism and which is directly or indirectly carried by said fixed part, or by a structure to which said striking mechanism is fixed, in order to brake said first surface by damping.
