Abstract

PURPOSE:To display the battery life securely in a simple constitution, by applying a fast-feed pulse generated by an external operation member to a driving circuit in accordance with the battery life detection signal, and fast-feeding the hand. CONSTITUTION:When an external operation member 60 such as a reset switch is operated, a fast-feed pulse generated by a fast-feed circuit 8 of timer, counter or the like is applied to a driving circuit 3, only when the battery voltage is lowered, through a gate controlled according to the voltage life detection signal from a power voltage detecting mechanism 7. As a result, after releasing the reset signal by the member 60 through pulse motor or the like 4, wheel train 5 and hand part 6, the hand is fast-fed, so that the battery life may be displayed securely according to the external operation member in a simple constitution.
