To reduce power consumption by operating hands only when needed. By operating to depress a mode changeover switch, a second hand is moved selectively to a hand operation start time setting mode (WAKE) position, a hand operation stop time setting mode (SLEEP) and an alarm time setting mode (ALARM) position. Hand operation stop time, hand operation start time and alarm time are set by setting an hour/minute hand to desired time by operating to depress a time setting switch in a state in which the second hand is disposed at the respective setting mode positions. When the hand setting stop time arrives, operation of the time hands is stopped and when the hand operation start time arrives, the time hands are fed fast to regular time and thereafter, normal time indicating operation is carried out. When predetermined time period before alarm time is reached in a state in which hand operation is stopped, the time hands carry out operation similar to the above-described and are recovered to normal operation and thereafter alarm is generated when the alarm time arrives.
