Abstract
A striking mechanism, particularly for a watch, includes at least one gong fixed to a gong-carrier, at least one hammer for striking the gong at predetermined times, and a device to select at least one mode of vibration of the gong. The selection device includes at least one selector element arranged in contact on a part of the gong and held on a vibration node of a mode of vibration of the gong to be selected so as to block other modes of vibration. The selector element can be moved on the gong by a mechanical or magnetic movement device.
