PROBLEM TO BE SOLVED: To solve such a problem that a solar battery has to be disassembled when a winding stem is attached or detached, in a conventional analog clock with the solar battery arranged on a back cover side because a part connected to the winding stem is covered by the solar battery. SOLUTION: A winding stem detaching lever 5 of a lever part, which is originally for detaching a winding stem 2 from the number plate 6 side, is placed and then the winding stem 2 with no disassembling a solar battery 7 can be detached by pulling up the point 5c of the lever 5 to the back 9 cover side through the back cover 9 side. A planar gap 1c, where a jig 10 can just be inserted between a ground plate 1 and the lever 5, is placed, and the structure is formed so as to enable detaching the stem 2 by pulling down the jig 10 with an end face 1d of the bottom plate 1 being set as a fulcrum of a lever.
