ABSTRACT:
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).
