The solar cell is accommodated in the watch case by being restrained by the lower surface of the peripheral portion of the windshield, and is not directly formed on the windshield, but does not reduce the strength of the tempered glass by heat. Therefore, it is possible to obtain a portable timepiece with a solar cell that can generate sufficient electric power without degrading the quality of the timepiece. Also, since the solar cell is not superposed on the dial plate in a plane, a normal metal dial plate can be used as the dial plate, so the product variation is enhanced without spoiling the aesthetics of the watch even with the solar cell mounted. Made it possible.
