ABSTRACT:
A removable cover (10) for closing an opening (15) of a battery housing in an electronic watch having an armature (7) which is a flat metal disc with central and peripheral openings in which a molded cylindrical packing member (9) is anchored. The back (14) of the watch case is formed with a circular opening (15) with a particular profile suited to the diameter of the packing member (9). The latter, by radial compression, secures the cover and provides fluid-tightness. All of the operations for mass-producing the cover (10) and fitting it are carried out mechanically, without manual intervention, and are automated.
