Abstract

PURPOSE: To obtain a smaller and thinner sized watch body with a high reliability by means of a metal reinforcing plate provided on the plastic member in which the main plate and back cover are molded unitarily.
CONSTITUTION: The back cover reinforcing plate 7 is molded unitarily on the watch back cover 1 by outsert. This checks the deformation otherwise caused during the plastic molding thereby improving the position accuracy of the wheel train guide section while the mechanical strength is enhanced as the back cover. The water proofing packing 15 is retained between the back cover reinforcing plate and the shell 14. In addition, the back cover reinforcing plate 7-i functions as the circuit lead plate as indicated by IC21 or the like.
