Abstract

PURPOSE: To produce the watch case, the resin part of the back side whereof is invisible, by filling resin in the electrocasting sheel obtained by applying conducting treatment and electrocasting the inside surface of the specific dies to form the inside diameter part of the case then performing rapping.
CONSTITUTION: A pair of upper and lower dies 1, 2 whose respective inside surfaces 1b, 2b conform to the upper and lower profiles of the watch case are fitted to respective engaging parts 1a, 2a and assembled. A conducting treatment film 3 is applied to the inside surface of the dies by means such as vapor deposition, electroplating, etc. and electrocasting is done to the specified thickness to form a shell 4. After resin is filled in this shell, it is machined to make the case inside diameter part 5. Next, the dies 1, 2 are parted and a protecting plating layer 6 is formed on the surface of the shell to complete the watch case. The resultant case has an inverted taper part 9 and therefore the resin part on the back side is invisible and at the same time it is easy to mount a back cover 8.
