Abstract

PURPOSE: To relax the movement at casing and the air pressure working on the package glass and control adverse effect due to atmospheric pressure by a means of improving the breathing property prior to the completion of engaging the back cover with the body of a watch provided on the body or the back cover.
CONSTITUTION: When a back cover 1 is mounted to the body 2 with a packing 3, air in the watch case escapes from the top of the packing through a horizontal hole 1b on a rib section 1a of the back cover 1. When the packing 3 is compressed vertically in a certain degree against the back cover 1 and the body immediately prior to the completion of engaging the cover 1 and the body, it is made airtight. With such an arrangement, the movement at casing and the air pressure working on the package glass are relaxed, thereby minimizing the adverse effect due to the atmospheric pressure.
