Abstract

PURPOSE:To make components of a wrist watch thin by ensuring a sufficient waterproofing effect with a light compression force on a highly tight seal coat formed on the surface of components in contact with an elastic packing. CONSTITUTION:A screw groove 1a is cut on the inner surface of a case body 1 on the side of the bottom thereof. A circuit packing groove 1b with a rectangular cross-section is formed on the bottom thereof. A seal film 2 is formed on the back or the bottom of the packing groove 1b. Then, an elastic packing 3 is inserted into the packing groove 1b. When a back cover 4 is screwed into the side body 1, the top of the circumferential flange of the back cover 4 presses against the bottom thereof to compress the elastic packing 3. Likewise, the seal film 2 is formed at the contact part between the back cover 4 and the elastic packing 3.
