2. Description of the Related Art Conventionally, radio timepieces equipped with a power generation means have been commercialized. Radio waves are received at a fixed time or manually, and when the power generation signal from the power generation means is not continuously present for a certain period, the hands of the hands are moved. A so-called power saving state such as interruption is made, and the receiving operation is not performed in this state to save energy.

However, in the above configuration, since the radio wave is not received during the power saving state for a long period of time, the time is shifted, and when the power generation signal from the power generation means is generated, the power saving period is corrected to the current time. The time remains off when the hands are moved at the time. After that, radio waves are received on a regular basis or manually. For this reason, the time is shifted from the time of returning from the power saving state for a long time until the next radio wave is received, and there is a period in which the accurate time is not displayed. It is an object of the present invention to always display an accurate time by moving the pointer at the current time when returning from the power saving state and performing automatic reception after the end of the hand movement.

2, the hand position conversion is interrupted, the movement of the second hand 28a, the minute hand 28b, the hour hand 28c and the date dial 28d is stopped to enter the power saving state. When the power saving state is entered and the dark state is continued, the dark time counter 19 outputs "H" to the PS signal S19 every hour for a certain period. The needle position conversion circuit A11 and the needle position conversion circuit B12 perform the needle position conversion every one hour, and the drive signal generation circuit A20 and the drive signal generation circuit B24 respectively output the difference pulse number to the target needle position as a drive signal, The second hand 28a, the minute hand 28b, the hour hand 28c, and the date plate 28d are moved for one hour through the converter drive circuit, the step motor, and the reduction gear train system. Since the second hand 28a and the minute hand 28b return to their original positions in 1 hour, they are not actually moved. In this way, in the power saving state, the hour hand 28c and the date dial 28d move the hourly. The solar cell 1 is operated every hour to save power.
It is a waiting time for the second hand 28a, the minute hand 28b, the hour hand 28c, and the date plate 28d to be restored at the present time when the light 7 hits, and since the hour hand 28c is only moved, the power saving effect is also taken into consideration.

Next, the operation of returning from the power saving state to the normal state will be described. When the solar cell 17 is exposed to light, the photodetection circuit 18 outputs "H" to the photodetection signal S18, and the dark time counter 19 stops counting and initializes and PS
"H" is output to the signal S19. Needle position conversion circuit A1
1. The hand position conversion circuit B12 performs the hand position conversion by the PS signal S19, and the second hand 28a, the minute hand 28b, the hour hand 28c, through the converter drive circuit, the step motor, and the reduction gear train system.
The date dial 28d starts moving hands to the current time. The PS signal S19 inputs "H" from "L" to the power saving cancellation detection circuit 33, and the second hand 28a, the minute hand 28b, the hour hand 28c, and the date plate 28d.
