Abstract
In one form of the structure for preventing inadvertent opening of a cover lid of a water-proof watch, a protrusion formed on the cover lid is locked into a recess formed at a head of a lock button. A coil spring is attached to the lock button to bias the same to maintain the engagement between the recess of the lock button and the protrusion of the cover lid so as to prevent inaduertent opening or unlocking of the cover lid. In another form of the opening and closing mechanism of a cover lid, a rod member is provided with a water-tight sealing and a coil spring, and operates to apply a pressing force to a hinge portion of the cover lid to assist in closing of the cover lid, thereby realizing simplified water-tight structure of the opening and closing of the cover lid.
