Abstract
An electronic watch is formed of a case body having a display window, a movement situated in the case body, a light transmitting digital display disposed above the movement in the case body to be observed from an outside through the display window, and a solar cell unit. The solar cell unit is interposed between a part of the light transmitting digital display and the movement, and a reflecting plate is disposed under another part of the light transmitting digital display adjacent to the solar cell unit. Also, a light transmitting material is interposed between the part of the light transmitting digital display and the solar cell unit. Thus, light is supplied to the solar cell unit from the outside through the light transmitting digital display.
