Electronic timepiece and electronic device
First Claim
1. An electronic timepiece comprises:
- an external operating member;
a mode setting unit that sets an operating mode of the timepiece based on an input operation of the external operating member;
a reception unit that receives a satellite signal transmitted from a positioning information satellite;
a reception control unit that controls operation of the reception unit based on the set operating mode; and
a time adjustment unit that adjusts internal time information based on the satellite signal received by the reception unit;
wherein based on a continuous input time for which the external operating member is operated continuously, the mode setting unit changes and sets the operating mode toa first mode that receives a satellite signal from one or more positioning information satellites and adjusts the internal time information based on time information contained in the received satellite signal, ora second mode that receives satellite signals from three or more positioning information satellites and adjusts the internal time information based on time information and positioning information contained in the received satellite signals; and
wherein the continuous input time when the mode setting unit sets the first mode as the operating mode is shorter than the continuous input time when the mode setting unit sets the second mode as the operating mode.

Abstract
An electronic timepiece enables a simple construction, and an electronic device has the electronic timepiece. A wristwatch 1 has a button A 6; a mode setting unit 32 that sets the operating mode of the wristwatch 1 based on an input operation of the button A 6. Based on the continuous input time that the button A 6 is operated continuously, the mode setting unit 32 changes the operating mode between a timekeeping mode that receives satellite signals from one or more GPS satellites and adjusts the internal time information based on time information contained in the received satellite signal(s); and a positioning mode that receives satellite signals from three or more GPS satellites and adjusts the internal time information based on time information and positioning information contained in the received satellite signals.

9. A control method of an electronic timepiece comprises:
-
determining a continuous input time during which an external operating member is operated continuously; when the continuous input time is greater than a first time, the control method further comprises receiving a satellite signal from one or more positioning information satellites, and adjusting a display time based on time information contained in the received satellite signal; when the continuous input time is greater than a second time, which is greater than the first time, the control method further comprises receiving satellite signals from three or more positioning information satellites, and adjusting the display time based on time information and positioning information contained in the received satellite signals.
