PROBLEM TO BE SOLVED: To efficiently configure a clock with a different display specification while utilizing as many common parts as possible. SOLUTION: In order to change a display body to create the clock with a new feature, without changing a step motor (second motor) and a driving wheel train (second wheel train), only the display body and a control circuit for driving it are changed (by changing the number of steps when display is changed). The display bodies to be changed are a day of the week plate, higher-order digit of a bigdate, 24-hour hand, world time disk, etc., as needed. Furthermore, to change drive control, changing control method using non-contact communication also allows the control circuit to be commonly utilized, and that enables more common utilization of a movement.
