ABSTRACT:
Shock absorbing members are attached to an outer rim of a back surface of a wristwatch case body at 6- and 12-o'clock portions thereof, and they extend outward and curve downward. Each of the shock absorbing members has rising portions extending from its both side ends and which are freely swingably attached to the wristwatch case body to a circumferential surface of the wristwatch case body. In addition, a part of a front surface and the circumferential surface of the wristwatch case body are covered by a first cover member made of soft synthetic resin, and the first cover is partly covered by a metal-made second cover member. When shock is applied to the front and circumferential surfaces of the wristwatch case body, the shock is reduced or absorbed by the rising portions of the shock absorbing members. When shock is applied to the back surface of the case body, the shock is reduced or absorbed by the shock absorbing member.
