Abstract

An electronic timepiece enables a simple construction, and an electronic device has the electronic timepiece. A wristwatch has a button or external operating member; a controller that sets the operating mode of the wristwatch based on an input operation of the button. Based on the continuous input time that the button is operated continuously, the controller changes the operating mode between a timekeeping mode that receives a satellite signal from one or more GPS satellites and adjusts the internal time information based on time information contained in the received satellite signal; 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.

First claim

What is claimed is:

1. An electronic timepiece comprising:
an external operating member;
a controller configured to:
set an operating mode based on a continuous input time for which the external operating member is operated continuously to
a 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, or
a 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

a receiver configured to receive one or more satellite signals based on the set operating mode;
wherein the continuous input time when the controller sets the first mode is shorter than the continuous input time when the controller sets the second mode.

2. The electronic timepiece described in claim 1 , wherein:
when the operating mode is the second mode, the controller calculates a standard time at the current location of the electronic timepiece and sets the internal time information based on the time information and positioning information contained in the satellite signals.

3. The electronic timepiece described in claim 1 , further comprising:
a reception result storage that stores a reception result indicating whether or not satellite signal reception by the receiver succeeded; and
a reception result display that displays the reception result;
wherein the controller sets a third mode that causes displaying the reception result stored in the reception result storage based on the continuous input time as the operating mode, and
when the third mode is set as the operating mode, the controller displays the reception result on the reception result display.

4. The electronic timepiece described in claim 3 , wherein:
the continuous input time when the controller sets the third mode is shorter than the continuous input time when the controller sets the first mode.

5. The electronic timepiece described in claim 1 , further comprising:
an operating time display that displays the operating time that the external operating member is operated continuously.

6. The electronic timepiece described in claim 1 , further comprising:
a set mode display that displays the operating mode corresponding to the operating time that the external operating member is operated continuously.

7. The electronic timepiece described in claim 1 , further comprising:
an operation mode display that displays the operating mode being executed.

8. An electronic device comprising the electronic timepiece described in claim 1 .

9. A control method of an electronic timepiece comprising:
determining a continuous input time during which an external operating member is operated continuously;
setting an operating mode based on the determined continuous input time for which the external operating member is operated continuously to
a 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, or
a 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

receiving one or more satellite signals based on the set operating mode;
wherein the continuous input time when the controller sets the first mode is shorter than the continuous input time when the controller sets the second mode.
