    Abstract: A mold producing one or more globe-shaped bells, each of which is cast as a one-piece shell enclosing a tumbling ball-bearing or jinglet. Production of the one-piece shell is made possible by pouring molten metal over a spherical core, supported by small "feet" inside the globe-like cavity of the mold. When the shell is removed from the mold, the core, in which the ball-bearing or jinglet is embedded, can easily be disintegrated or broken down into particles which fall out holes in the shell's surface.

    Abstract: The invention relates to a percussion bell comprising a bell and a hammer mounted on a base provided with a collar for clamping around a mounting. The collar being arranged with an installation axis (A′) of the mounting, a sagittal installation plane (M′) containing the outermost portion of the collar, as well as a transverse plane (T) perpendicular to the installation plane (M′) and containing the installation axis (A′). The hammer has a central portion rotatably mounted on the base and topped by an upper tab provided with a percussion area. The hammer also has a lower tab for movement provided with an actuating area, the percussion area extends above the transverse plane (T), and the actuating area extends below the transverse plane by being offset outwards relative to the installation plane (M′).

    Abstract: A musical timepiece includes a gong fastened to a structure or a resonator of a watch case, the resonator rigidly assembled to the structure around a chamber, by lugs allowing vibration of the resonator within a determined frequency range, the chamber enclosing a sealing element forming with the lugs the only mechanical connection between the structure and the resonator. The structure or the resonator includes a groove receiving a gasket in contact with the structure and the resonator The structure structure or the resonator or the sealing element includes a rigid protruding relief portion compressing a gasket in its groove, with a hardness less than 20 Shore A, for minimum damping of the vibration of the resonator.
