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.

Bracelet clasp () with a buckle () having strands carrying shouldered pins () cooperating with eyes () in the buckle, with two pushers () antagonistic against springs, each controlling two bolts (), where the first pusher () integrally drives a first bolt () opposite a first pin () and a second bolt () opposite a second pin (), this first pin () and a second bolt () opposite this second pin (), so that only the combined actuation of the two pushers () drives all of the bolts () through their entire release travel to release these pins () and one of the bolts () remains locked during insertion of a pin () in an eye ().

Triple unfolding clasp

The protective case includes a back cover () and a cover (), which are provided to fit together. The case further includes a flange (), inserted in the back cover and held laterally by the edge (), and an elastically deformable stake (), which is for immobilizing a plate-shaped part pierced with an aperture (). The stake is mounted on the top surface of the flange and it is inserted into the aperture of the plate-shaped part. The bottom surface of the cover () further carries a projecting portion () that presses against the stake when the case is closed, so as to increase the external diameter of the stake and jam it in the aperture of the plate-shaped part. Elastic means () are also provided for returning the flange () in the direction of the cover () so as to hold the stake () jammed in the aperture in the plate-shaped part.
