ABSTRACT:
A non-reversible battery and mounting assembly for an electrically powered watch includes a battery having a casing defining a generally cylindrical configuration with an annular radially extending shoulder adjacent one end thereof for engaging an inwardly directed shoulder on a battery cavity of a component housing. The shoulder within the component housing being positioned such that the battery will fit within the cavity in only one orientation with a retaining ring engaging the flange on the battery case for retaining the battery within the housing. The back of the battery also serves as the back of the watch case eliminating the need for a separate back therefor. The retaining ring is provided with a hole for receiving the point of a ballpoint pen or similar object for use in removing the retainer ring.
