The invention concerns a timepiece, specifically a wrist watch, including a fluid resistant container (19) provided with a framework (20) of plastic material housing the horometric components. Such fluid resistant container (19) is closed by a crystal (22) and by a cell holder compartment lid (40) keyed to the framework and it is fitted out with a stem (26) on such framework rendered fluid resistant. The container is assembled and maintained in place in a metallic case (2) by snap securing means, in particular a bezel (18) which axially compresses a flange (20a) of the framework (20) and a toroidal seal (42) against the case (2). The case can thus be manufactured with loose tolerances. The assembled fluid resistant container and horological movement can be tested prior to its assembly in the case (2).
A timepiece including an autonomous fluid resistant container provided with a framework of plastic material and housing horometric components, said fluid resistant container being mounted in a metallic case and maintained in place in said metallic case by securing means, said fluid resistant container being closed by a crystal and fitted out with a control stem rendered fluid resistant on the framework, the securing means including an annular element snap mounted on the case, a projecting flange on said framework and a compressible annular seal arranged between the projecting flange and the case in a manner such that said flange and said seal are axially compressed between the annular element and the case.
