  • Patent number: 5245591
    Abstract: An analog timepiece has a standard signal generator, a reversely rotatable minute pulse motor and a reversely rotatable hour pulse motor. Current time is measured based on a standard signal from the standard signal generator and stored in a current time memory. The current time stored in the current time memory is converted to a minute hand desired position and an hour hand desired position which are stored in a desired position memory. A minute hand indicating position indicated by a minute hand and an hour hand indicating position indicated by an hour hand are stored in an indicating position memory. The minute pulse motor and the hour pulse motor are driven until the minute hand indicating position and the hour hand indicating position coincide with the minute hand and hour hand desired positions.
