Abstract

PURPOSE:To provide a solar-battery driven write watch, in which inner walls of a light taking window formed in a solar-battery retaining plate are made of material having a high light reflecting factor, so as to minimize dependency of the amount of light available for the solar batteries on the incident angle of the same, whereby it is enabled to obtain a constant output current under a lighting having a high directivity.
