Striking or musical timepiece with a resonant bezel

A watch case comprising:

• a rigid structure, and at least one resonator component arranged to be rigidly assembled, directly or indirectly, to said structure, said resonator component defining with said structure, when the latter are assembled to each other in an assembled operating position, a chamber which encloses, between said structure and said resonator component, at least one sealing element comprised in said watch case
• wherein said watch case includes at least one rigid protruding relief portion arranged, in said assembled position, to exert a compression force on a gasket opposite a median area of a groove which receives said gasket, said at least one protruding relief portion forming part of said structure or of said resonator component or of said sealing element, and
• wherein said structure comprises a first groove and said resonator component comprises a second groove remote from said first groove,
• wherein said sealing element comprises at least a first gasket and a second gasket remote from each other and connected to each other by a sealed membrane extending between said first groove and said second groove, and
• wherein said structure includes a first protruding relief portion arranged to cooperate with said second gasket opposite said second groove, and said resonator component includes a second protruding relief portion arranged to cooperate with said first gasket opposite said first groove to prevent removal of said sealing element from said chamber in said assembled operating position.

A watch case, comprising:

• wherein said structure comprises a first groove and said resonator component comprises a second groove substantially opposite said first groove,
• wherein said sealing element comprises at least a first gasket and a second gasket remote from each other, and
• wherein said sealing element includes a rigid protruding relief portion arranged to connect the first gasket and the second gasket and to cooperate both with said first gasket opposite said first groove and with said second gasket opposite said second groove to prevent removal of said sealing element from said chamber in said assembled operating position.
