A circular case battery hole is formed in the case back right below a battery accommodation hole, and in a portion of the outer surface around the battery hole is provided a battery cover detachment recess portion. A battery cover is formed of a disklike elastic sealing member having a large-diameter portion at its watch case interior side and a small-diameter portion at its outer side, and a disklike hard member made of a metal, a plastic, or the like joined to outer side of the elastic sealing member.

In the battery cover of this embodiment, the elastic sealing member has a fitting recess portion at its outer side while the hard member has an fitting projection portion at its internal side, and the elastic sealing member and the hard member are joined by projection-recess fitting.
