For the development of our new solar CQ, special emphasis has been put on the following points : (1) the watch does not easily stop , (2) charge time required is not long , and (3) the watch face design is attractive. The methods we have adopted to satisfy these points are : (A) the structure in which the solar cell and the liquid crystal cell are laminated , and (B) the use of a glass-made solar cell. By use of these two methods, the development of high-performance attractive solar CQ not available so far has been attained.
