Abstract

PROBLEM TO BE SOLVED: To provide an analog clock with a solar cell of a design for preventing the presence of the solar cell from being identified at a glance. SOLUTION: In a dial 5, four openings 51 are provided radially with the rotary center of pointers 62 and 63 as the center so that the entire part has a cross shape, and a solar cell 7 is mounted to each opening while the solar cell 7 is exposed. The solar cell 7 is provided with lines 73, and the dial 5 between the openings 51 is provided with a camouflage pattern P with lines 52 that are nearly continuous to the lines 73 of the solar cell 7. The camouflage pattern P of the dial 5 is formed into one piece with the line pattern of the solar cell as a whole, gives a camouflage effect in a harmony, and operates so that it does not make every body feel the presence of the solar cell 7.
