PROBLEM TO BE SOLVED: To enable a motor less frequently used to quickly rotate even in a low-temperature environment.SOLUTION: In an analog electronic chronometer that has a chrono-motor 110 for rotationally driving chronograph hands 117, 118 and 113, a time motor 111 for rotationally driving time hands 114, 115 and 116, and control means for driving the motors 110 and 111, and in which the chrono-motor 110 is driven less frequently than the time motor 111 is, the control means vibrates the chrono-motor 110 by driving the chrono-motor 110, in a non-driving mode in which the chrono-motor 110 is not driven, so that the chronograph hands 117, 118 and 113 may not be rotated by the chrono-motor 110. |
