Abstract
To provide a radio-controlled timepiece capable of directing a standard time radio wave receiving antenna toward the suitable direction to a station easily and surely. The radio-controlled timepiece is to receive a standard time radio wave including time information in a standard time radio wave receiving unit and correct the time display based on the time information of the standard time radio wave received by the above receiving unit, and it includes a position calculating unit for detecting the direction of the station transmitting the standard time radio wave, based on a standard time radio wave signal received by the standard time radio wave receiving unit.
Claims4
A radio-controlled timepiece comprising:
- standard time radio wave receiving means for receiving a standard time radio wave including time information;
- correcting time means for correcting time display based on the time information of the standard time radio wave received by the receiving means;
- and
- direction detecting means for detecting a direction of a station which transmits the standard time radio wave based on a standard time radio wave signal received by the standard time radio wave receiving means.
A radio-controlled timepiece comprising:
- a standard time radio wave receiver to receive a standard time radio wave including time information;
- a correcting time circuit to correct time display based on the time information of the standard time radio wave received by the receiver;
- and
- a direction detecting circuit to detect a direction of a station which transmits the standard time radio wave based on a standard time radio wave signal received by the standard time radio wave receiver.
