PROBLEM TO BE SOLVED: To provide a clock capable of easily performing mode discrimination in a clock movement state in a clock with a chronograph of a type which can switch a normal time mode and a chronograph, electrically performs drive control of a chronograph pointer and mechanically performs return-to-zero to an initial position.SOLUTION: A plurality of levers operating when modes are switched and configured in a chronograph mechanism are used. Since the levers cannot be visually recognized because a mandarin duck operation hole does not overlap the levers in a planar view in a normal time mode. On the other hand, the levers can be visually recognized because the mandarin duck operation hole overlaps the levers in a planar view in a chronograph mode. Then, mode discrimination can be easily performed by confirming the mandarin duck operation hole. Further, a winding stem cannot be removed because the levers close the mandarin duck operation hole in the chronograph mode. |
