In the normal mode, the hand movement control unit 3 controls the driving of the pointer for normal time display based on the time information output from the time information management unit 22 and the clock pulse and pulse signal.

In the normal mode, the hand movement control unit 3 outputs a second drive pulse signal PS1 that is output once per second to drive the second hand, and an hour / minute drive pulse signal P that is output once per minute to drive the hour / minute hand.
S2 is output to the second drive circuit 41 and the hour / minute drive circuit 42 to control the driving of the hands. That is, each drive circuit 41, 42 drives a second motor 411 and an hour / minute motor 421 including a stepping motor driven by a pulse signal from each drive circuit 41, 42, and is thereby connected to each motor 411, 421.

The second position counter 611 counts the drive pulse signal (second drive pulse signal PS1) supplied from the hand movement control unit 3 to the second drive circuit 41. That is, the position of the second hand indicated by the second hand is counted by counting the drive pulse signal for driving the second hand.
The second time counter 612 normally counts a 1 Hz reference pulse signal (clock pulse) output from the hand movement control unit 3. When a time correction instruction is output from the time information management unit 22, the hand movement control unit 3 reads the time data from the time data storage circuit unit 24, and the counter value is matched with the second data of the time data.

12 and 622 are detected, and a detection signal indicating whether or not they match is output to the hand movement control unit 3.
When a mismatch signal is input from each of the match detection circuits 613 and 623, the hand movement control unit 3 continues to output the drive pulse signals PS1 and PS2 until the match signal is input. For this reason, during normal hand movement, when the counter values of the time counters 612 and 622 are changed by the reference signal of 1 Hz from the hand movement control unit 3 and do not coincide with the position counters 611 and 621, the drive pulse signals PS1 and PS2 are output As the hands move, the position counters 611 and 621 coincide with the time counters 612 and 622. By repeating this operation, normal hand movement control is performed.
Further, the time data read from the time data storage circuit unit 24 is used as each time counter 612,
When 622 is corrected, the drive pulse signals PS1 and PS2 continue to be output until the counter values of the position counters 611 and 621 coincide with the counter values, and the hands are fast-forwarded and corrected at the correct time.

FIG. 4 is a flowchart illustrating processing when the electronic timepiece 100 and the mobile device 200 perform wireless communication for the first time.
First, when the mobile device 200 and the electronic timepiece 100 start wireless communication for the first time according to the Bluetooth LE standard, the electronic timepiece 100 within a range where radio waves reach when viewed from the mobile device 200 side, The process of joining the network is required.
To start these processes, an application program for wireless communication with the electronic timepiece 100 is started in the portable device 200 (FIG. 4: step S20). When the application program is activated, a search button indicating, for example, “Search for an electronic watch” is displayed on the display unit 203 of the mobile device 200.

Second Embodiment
A second embodiment of the present invention will be described with reference to FIG. In this embodiment,
In addition to the processing of the first embodiment, the time accuracy of the electronic timepiece is calculated. FIG.
These are the flowcharts of the communication processing in this embodiment. The same step numbers are attached to common portions with the flowchart of FIG. 4 in the first embodiment.
In the present embodiment, as shown in FIG. 10, a time comparison display (FIG. 10: Step S22).
), The portable device control unit 201 of the portable device 200 performs a process of calculating and storing the time accuracy of the electronic timepiece 100 (FIG. 10: Step S40). Accordingly, the portable device control unit 201 functions as a control unit that calculates the time accuracy of the electronic timepiece 201 from the reference time information, the clock time information, and the elapsed time from the time when the time was most recently corrected. .
Note that the calculation of time accuracy is preferably performed at the time of communication more than a certain time after the time data is first exchanged.

The time accuracy is calculated from the difference between the time based on the time data received from the electronic timepiece 100 at a certain time and the time based on the GPS time data of the mobile device 200 at that time.
(Equation 1)
Time accuracy = (time of electronic clock−time of portable device) ÷ elapsed time Here, the elapsed time is the elapsed time from the time when the most recent time was corrected.

For example, if the elapsed time is 24 hours (86400 seconds) and the time difference at that time is 0.864 seconds,
Time accuracy = (0.864) ÷ 86400 = 10 × 10 ⁻⁶
Thus, the time accuracy is calculated as 10 ppm. The portable device 200 stores this value in a memory or the like as the time accuracy of the electronic timepiece (FIG. 10: Step S40).

When the time accuracy is 10 ppm, it can be considered that a deviation of about 1 second occurs in about 28 hours. Therefore, even when the mobile device 200 is not connected to the electronic timepiece 100, the time correction is performed to the user when the time difference calculated from the time accuracy becomes a predetermined value or more.

Therefore, the portable device control unit 201 functions as a control unit that causes the display unit 203 to display a display prompting the update of the clock time information to the reference time information based on the time accuracy.

Further, based on the calculated time accuracy, the communication parameters may be changed within a range where the time difference does not reach a certain level (FIG. 10: Step S40). For example, the interval T may be changed to a long time, and the frequency of communication between the electronic timepiece 100 and the portable device 200 may be lowered. By changing the communication parameters, the power consumption can be kept low.

YES), processing in a normal communication state as shown in FIG. 10 is performed (FIG. 11: step S52).

If the electronic device 100 cannot be found (see FIG. 11: Step S)
51; NO), the estimated time of the electronic timepiece 100 is calculated based on the time accuracy described in the second embodiment and the elapsed time from the time at which the most recent time was corrected (FIG. 11: Step S53).
). Then, the portable device 200 causes the display unit 203 to compare and display the time based on the GPS time data and the calculated estimated time (FIG. 11: step S54).

When the calculated estimated time shift with respect to the time based on the GPS time data is greater than or equal to a certain value, the portable device 200 displays a message prompting execution of time correction as in the above-described embodiments. Here, when the user taps the clock image on the mobile device 200 (FIG. 11: Step S55; YES), the time in the electronic clock time display column 212 is set to GPS time data as shown in FIG. The time is corrected based on (FIG. 11: Step S56). When the process for terminating the communication application by the user is not performed (FIG. 11: Step S57; YES), the mobile device 200 continues the display (FIG. 11: Step S57).
Thereafter, when the user sets the electronic timepiece 100 to the communication mode, the GPS time data and the time correction instruction are transmitted from the portable device 200 to the electronic timepiece 100, as in the first embodiment, Time correction is performed in the timepiece 100.

When the processing for terminating the communication application by the user is performed or when a certain timeout time is reached (FIG. 11: Step S57)
NO), the communication application is terminated (FIG. 11: Step S59). Thereafter, when the user activates the communication application again and sets the electronic timepiece 100 to the communication mode, the portable device 200 applies the electronic timepiece 100 to the electronic timepiece 100 as in the first embodiment.
