  FIG. 2 is a block diagram showing a functional configuration of the electronic timepiece 1 of this embodiment.

  The electronic timepiece 1 includes an hour hand 11, a stepping motor 31 for rotating the hour hand 11 via a train wheel mechanism 21, a minute hand 12, and a stepping motor 32 for rotating the minute hand 12 via a train wheel mechanism 22. A second hand 13, a stepping motor 33 for rotating the second hand 13 via the train wheel mechanism 23, a date indicator 14, a stepping motor 34 for rotating the date indicator 14 via a train wheel mechanism 24, and a drive circuit 30. , A microcomputer 40, a ROM 51 (Read Only Memory), an operation reception unit 52, a notification unit 53, a satellite radio wave reception processing unit 54 (radio wave reception unit, satellite radio wave reception unit) and an antenna AN1, a communication unit 55 and an antenna. The AN 2 and the power supply unit 60 are provided.

  The microcomputer 40 includes a CPU 41 (Central Processing Unit), a RAM 42 (Random Access Memory), an oscillation circuit 44, a frequency dividing circuit 45, a clock circuit 46, and the like.

The CPU 41 and the RAM 42 configure a control unit 40a that functions as a processor that integrally controls the overall operation of the electronic timepiece 1 of this embodiment.
The CPU 41 performs various arithmetic processes, acquires signals from each unit as necessary, and outputs a control signal to each unit. For example, the CPU 41 has an hour hand 11, a minute hand 12, a second hand 13 and a date indicator 14 (display unit; hereinafter, a part or all of them are collectively referred to as pointers 11 to 14 and the like) with respect to the drive circuit 30 at appropriate timings. Outputs a control signal for rotating.

  The RAM 42 provides the CPU 41 with a working memory space and stores temporary data. The temporary data stored in the RAM 42 includes setting data and history data related to each function. The setting data related to each function includes, for example, identification information 421 (setting) of the external device that is communicatively connected when the communication unit 55 communicates with the external device by Bluetooth (registered trademark). Further, the history data includes, for example, the latest timing at which the date and time information was externally acquired and the acquisition type.

  The oscillator circuit 44 generates a predetermined frequency signal and outputs it to the frequency dividing circuit 45. A crystal oscillator is used as the oscillation circuit 44 here. The crystal oscillator in this case may be externally attached to the microcomputer 40.

  The frequency dividing circuit 45 frequency-divides the frequency signal input from the oscillation circuit 44, generates a signal having a frequency set by the control signal from the CPU 41, and outputs the signal to the CPU 41. Further, the frequency dividing circuit 45 generates a predetermined frequency signal (for example, 1 second signal) and outputs it to the time counting circuit 46.

  The clock circuit 46 is a counter that counts the input frequency signal and counts the date and time. Alternatively, the clock circuit 46 may be a memory such as a DRAM that stores the date and time counted by the CPU 41 by software.

  The ROM 51 stores various programs 511 executed by the control unit 40a (CPU 41) and initial setting data used by these programs 511. The program 511 and the initial setting data are read by the CPU 41 at the time of starting the electronic timepiece 1 and as needed, and are executed and used. The ROM 51 may have various non-volatile memories such as a rewritable flash memory and an EEPROM (Electrically Erasable and Programmable Read Only Memory) in addition to or instead of the mask ROM.

  The operation receiving unit 52 detects and receives an input operation from the outside such as an input operation by the user, converts the input operation into an electric signal, and outputs the electric signal to the CPU 41 as an input signal. The operation receiving section 52 includes push button switches B1 and B2 and a crown C1 as operation members. The user can correct the current date and time (time), perform positioning, and perform operations related to other various functions by inputting operations via the push button switches B1 and B2 and the crown C1. ..

  The notification unit 53 performs a predetermined notification operation for the user. Examples of the predetermined notification operation include buzzer sound generation, vibration generation, and lamp lighting (flashing) operation. The notification unit 53 has one or more of the configurations corresponding to these operations. For example, a piezoelectric element having electrodes on both ends and a diaphragm are used to generate a buzzer sound. To generate the vibration, for example, a rotary motor provided with a weight is used. Further, for lighting the lamp, for example, an LED is used.

  The satellite radio wave reception processing unit 54 receives a radio wave (broadcast radio wave including time information) from a positioning satellite via the antenna AN1, obtains a date and time, performs a positioning calculation, and outputs it to the CPU 41. The positioning satellite to be received by the satellite radio wave reception processing unit 54 is, for example, a positioning satellite related to the United States GPS (Global Positioning System), but it is possible to receive the radio waves of other positioning satellites and use them for positioning. May be In addition, a CPU, a calculation circuit, and the like that perform positioning calculation may be included in the control unit 40a described above. These can be arranged in a module of the satellite radio wave reception processing unit 54 together with a reception unit that performs radio wave tuning, amplification, capture, demodulation (inverse spectrum spread), etc., but are also arranged together with the CPU 41, RAM 42, etc. May be.

  The communication unit 55 performs communication control with an external electronic device (external device) that is set via the antenna AN2 to perform mutual wireless communication (wireless communication). Although not particularly limited, the communication unit 55 controls communication in accordance with the Bluetooth protocol here. As Bluetooth communication, the power saving communication of version 4 can be used here, and the power consumption required for one communication is not so large as the power consumption required for the normal operation of the electronic timepiece 1. Instead of or in addition to this, high-speed communication of version 3 or another version may be available for Bluetooth communication.

  The power supply unit 60 supplies the microcomputer 40 with necessary power at a predetermined operating voltage. The power supply unit 60 is not particularly limited, but includes, for example, a solar panel and a secondary battery as a battery, and enables long-term and stable power supply. Alternatively, power may be supplied to the power supply unit 60 from a primary battery such as a detachable button type dry battery. When the output voltage of the battery is different from the operating voltage of each unit, the power supply unit 60 converts the voltage and outputs the voltage to each unit. Further, in the satellite radio wave reception processing unit 54, the communication unit 55, and the like, the presence / absence of supply of power from the power supply unit 60 can be switched directly by the control of the microcomputer 40 (CPU 41).

  The stepping motors 31 to 34 are step-driven based on the voltage waveforms of the drive pulses input from the drive circuit 30, respectively, and the pointers 11 to 14 are independently rotated in the forward direction (direction in which time and time advance) or reverse direction. It is possible to rotate and move by a predetermined angle in the (time and time return direction). Each of these stepping motors 31 to 34 can be driven by a drive pulse of 64 pps (pulse per second) at the fastest in the forward rotation direction, and can be driven by a drive pulse of 32 pps at the fastest in the reverse rotation direction. is there.

  The drive circuit 30 outputs a drive pulse having a pulse width set to each of the stepping motors 31 to 34 based on a control signal output from the CPU 41 and related to the operation of the hands 11 to 14. The drive circuit 30 is configured not to output drive pulses to a plurality of stepping motors at the same time. That is, when a hand movement command for a plurality of hands is input at the same time, the drive circuit 30 sequentially outputs drive pulses to the stepping motors according to the priority set in advance for the hands to be moved. To do.

  In the electronic timepiece 1 of the present embodiment, each time the stepping motors 31 to 34 are driven by one step, the hour hand 11 and the minute hand 12 rotate 1 degree, the second hand 13 rotates 6 degrees, and the date dial 14 moves 1 /. The train wheel mechanisms 21 to 24 are configured to rotate 124 degrees (360 / (31 × 1440) degrees). Therefore, in the normal time display mode, the second hand 13 rotates one step every second based on the input interval of the drive pulse to the stepping motor 33, and the minute hand 12 interlocks with the movement of the second hand 13 to display the 1-second digit. It rotates one step every 10 seconds at the timing of "0" (1:10 by the time ratio), and the hour hand 11 interlocks with the movement of the minute hand 12 and performs one step every two minutes at the timing when the one-minute digit becomes an even number. The operation is controlled so that it rotates (time ratio 1:12). The date indicator 14 changes its rotation by 1440 steps by fast-forwarding at the turn of the date, that is, every other time at which the hour hand 11 points in the 12 o'clock direction, and the display changes by one day.

  In addition, the second hand 13 displays the date and time information and the current position information according to the acquisition content and the type of acquisition means when performing the date and time correction operation and the positioning operation.

Next, the date and time correction operation in the electronic timepiece 1 of this embodiment will be described.
In the electronic timepiece 1 according to the present embodiment, at the time of Bluetooth communication connection with an external device via the communication unit 55, date and time information and current position information (current time information and current position information) from the connected external device. To get. The current position information referred to here includes information on positions in a wide range such as a time zone and a local time setting area. The communication connection with the external device is performed at any timing based on the input operation by the user, and in addition to the connection for acquiring the date and time information and the current position information once or a plurality of times every day at a predetermined time. It is done automatically. The time required to acquire the date and time information and the current position information from the external device is short, for example, about 1 second to several seconds, and the power consumption is small. For Bluetooth communication with an external device, identification information of the external device needs to be set in advance and held in the RAM 42. As the external device, a portable electronic terminal that is easily used together with the electronic timepiece 1, such as a smartphone, is mainly cited, but the external device is not limited to this. It may be a fixed terminal, or various servers on the Internet line.

  On the other hand, in the electronic timepiece 1, the operation of the satellite radio wave reception processing unit 54 can acquire the date and time information from the positioning satellite and perform the positioning to identify the current position. Further, when the positioning is performed, the time zone to which the identified current position belongs and the local time setting such as the daylight saving time implementation setting are also acquired, and the date and time display may be adjusted. Acquisition of such date and time information and positioning can be performed based on the user's operation. In addition, in the electronic timepiece 1, when the date and time cannot be acquired by Bluetooth, the satellite radio wave reception processing unit 54 is activated once a day under a predetermined condition to acquire the date and time.

  The acquisition of the date and time by the satellite radio wave reception processing unit 54 requires about several seconds to 10 seconds according to a well-known algorithm when the position information of the receivable positioning satellite is not held in advance. The date and time can be obtained anywhere in the world as long as radio waves from any positioning satellite can be received outdoors. However, the power consumption required for the operation of the satellite radio wave reception processing unit 54 is significantly larger than the power consumption required for the normal operation of the electronic timepiece 1 and the communication operation by Bluetooth. In addition, positioning takes about 20 seconds to 1 minute, and the power consumption becomes larger than that at the time of acquisition of the date and time depending on the length of the reception processing time.

  An operation of acquiring date and time information and current position information by the communication unit 55 (first information acquisition operation), an operation of acquiring date and time information by the satellite radio wave reception processing unit 54 (second information acquisition operation), and a satellite radio wave reception processing unit. The positioning operation by 54 is switched according to the operation accepted by the push button switch B1. In the electronic timepiece 1 of the present embodiment, selection is performed according to the presence or absence of identification information (setting) of the external device that is the communication connection destination by Bluetooth. In the electronic timepiece 1, the predetermined input operation first accepted is the date / time information acquisition operation command (information acquisition command related to the current time), and the communication unit 55 (external device) is used as the date / time information acquisition means (acquisition destination). ) Or the satellite radio wave reception processing unit 54 (positioning satellite) is selected, and the selection is changed or the positioning operation is changed according to a further input operation.

FIG. 3 is a flowchart showing a control procedure by the control unit 40a of the function selection control process executed by the electronic timepiece 1 of this embodiment.
This function selection control process, which is an embodiment of the information acquisition control method of the present invention, detects that the push button switch B1 is continuously pressed for a predetermined time, here, for 1 second (predetermined input operation). Be started. That is, the function selection control process is started regardless of whether or not the pressed state of the push button switch B1 is released.

  When the function selection control process is started, the control unit 40a (CPU 41) determines whether or not a communication connection partner (pairing setting) related to Bluetooth communication has been set (step S101). If it is determined that it has not been performed (“NO” in step S101), the process of the control unit 40a proceeds to step S122.

  When it is determined that the pairing is set (“YES” in step S101), the control unit 40a outputs a control signal to the drive circuit 30 to move the second hand 13 to the position of the marker “C”. (Step S102). The control unit 40a activates the communication unit 55 (step S105). The control unit 40a establishes a Bluetooth communication connection with the external device for which the pairing setting has been made, and acquires date and time information (step S106). The control unit 40a may disconnect the communication connection as soon as the date and time is acquired, but may also acquire other information.

  The control unit 40a determines whether it is within a predetermined time (second reference time) from the activation of the communication unit 55 (step S107). When it is determined that it is within the predetermined time (“YES” in step S107), the control unit 40a detects the pressing operation of the push button switch B1 (usually the pressing operation by the user) (input of the predetermined operation member). It is determined whether or not the operation is detected again (step S108). When it is determined that it has been detected (“YES” in step S108), the process of the control unit 40a proceeds to step S122. When it is determined that it has not been detected (“NO” in step S108), the process of the control unit 40a returns to step S107.

  When the process proceeds from step S122 to step S122, the controller 40a outputs a control signal to the drive circuit 30 to move the second hand 13 to the position of the marker "TIME" (step S122). The control unit 40a activates the satellite radio wave reception processing unit 54 to start the date and time information acquisition operation (step S123). That is, the control unit 40a causes the satellite radio wave reception processing unit 54 to capture the radio waves of at least one positioning satellite and acquire the information necessary for identifying the date and time from the captured positioning satellite. At this time, the control unit 40a may disconnect the wireless communication connection with the external device by the communication unit 55. If the date / time information has already been acquired at this point, the control unit 40a discards the date / time information. Note that the control unit 40a may reflect the already acquired date / time information once and correct the date / time counted by the clock circuit 46.

  The control unit 40a determines whether date and time information has been acquired from the satellite radio wave reception processing unit 54 (step S124). When it is determined that the information has been acquired (“YES” in step S124), the process of the control unit 40a proceeds to step S129. When it is determined that the push button switch B1 is not acquired (“NO” in step S124), the control unit 40a determines whether or not the pressing operation of the push button switch B1 is detected (step S125). When it is determined that it has not been detected (“NO” in step S125), the process of the control unit 40a returns to step S124.

  When it is determined that the push-down operation of the push-button switch B1 is detected (that is, during the period from the activation of the satellite radio wave reception processing unit 54 to the acquisition of the date and time information (within the third reference time), the push-button switch B1 is operated). If detected again ("YES" in step S125), the control unit 40a outputs a control signal to the drive circuit 30 to move the second hand 13 to the position of the marker "T + P" (step S126). The control unit 40a outputs a control signal to the operating satellite radio wave reception processing unit 54 to shift from the date / time acquisition operation to the positioning operation (step S127). When the satellite radio wave reception processing unit 54 cannot shift from the date / time acquisition operation to the positioning operation on the way, the control unit 40a suspends (stops) the operation of the satellite radio wave reception processing unit 54 once and restarts the date / time acquisition operation. May be. The control unit 40a acquires the positioning result (that is, the information regarding the current time and the information regarding the current position) from the satellite radio wave reception processing unit 54 (step S128). Then, the processing of the control unit 40a moves to step S129.

After shifting from the processing of steps S124 and S128 to the processing of step S129, the control unit 40a stops the operation of the satellite radio wave reception processing unit 54 (step S129). Then, the control unit 40a ends the function selection control process.
Of the above processes, each process of steps S101, S106, and S123 constitutes an operation selecting step (operation selecting means) in the information acquisition control method (program) of this embodiment.

FIG. 4 is a flowchart showing a modified example 1 of the function selection control process.
In the function selection control process of the first modification, the processes of steps S103, S104, S120, and S121 are added to the function selection control process shown in FIG. 3, and the processes of steps S107 and S108 are omitted. .. The other processing contents are the same, the same processing contents are designated by the same reference numerals, and detailed description thereof will be omitted.

  When it is determined that the pairing setting is performed in the determination process of step S101 (“YES” in step S101), the control unit 40a detects that the push button switch B1 is released (released). It is determined whether or not (step S120). When it is determined that the push button switch B1 is not detected (“NO” in step S120), the control unit 40a determines that the push button switch B1 is pressed for 2 seconds (first reference time). ) It is determined whether or not the above continues (step S121).

  When it is determined that the pressed state has not continued for 2 seconds or more (“NO” in step S121), the process of the control unit 40a returns to step S120. If it is determined that two seconds or more have elapsed (“YES” in step S121), the process of the control unit 40a proceeds to step S122. In the determination processing of step S120, when it is determined that the release of the pressed state of the push button switch B1 is detected (that is, released in less than 2 seconds) in the determination processing of step S120 (“ YES "), the control unit 40a ends the function selection control process.

  Further, after the processing of step S102, the control unit 40a determines whether or not release (release) of the pressed state of the push button switch B1 is detected (step S103). When it is determined that it has not been detected (“NO” in step S103), the control unit 40a determines that the pressed state of the push button switch B1 (duration of a predetermined input operation) is 2 seconds (first reference time). ) It is determined whether or not the above continues (step S104). When it is determined that it has not continued for 2 seconds or more (“NO” in step S104), the process of the control unit 40a returns to step S103. If it is determined that two seconds or more have passed (“YES” in step S104), the process of the control unit 40a proceeds to step S122.

  When it is determined in the determination process of step S103 that the release of the pressed state of the push button switch B1 is detected (that is, the release is performed in less than 2 seconds) (“YES” in step S103), the control unit 40a. The process proceeds to step S105. After the processing of steps S105 and S106 ends, the control unit 40a ends the function selection control processing.

FIG. 5 is a flowchart showing a modified example 2 of the function selection control process.
In the function selection control process of the second modification, the processes of steps S103, S104, S120, S121, S131 to S133, and S141 are added to the function selection control process shown in FIG. 3, and steps S107, S108, S124, The process of S125 is deleted. The other processing is the same, and the same processing content is denoted by the same reference numeral and the description thereof is omitted. Further, the processes of steps S103, S104, S120, and S121 are the same as those of the modification 1 described above, and the description thereof will be omitted.

  After the processing of step S123, the control unit 40a determines whether or not the number of positioning satellites captured within the predetermined time is the number of positioning satellites required for positioning, that is, four or more (step S131). If it is determined that the number is not four or more (“NO” in step S131), the control unit 40a acquires date and time information from the satellite radio wave reception processing unit 54 (step S141), and then performs the function selection control process. finish.

  When it is determined that the number of captured positioning satellites is four or more (three or more if height direction information is not required) (“YES” in step S131), the control unit 40a It is determined whether or not the SNR (reception intensity) of the received signal is equal to or higher than a predetermined reference value for four or more radio waves from the captured positioning satellites (step S132). When it is determined that the value is not the reference value or more (“NO” in step S132), the process of the control unit 40a proceeds to step S141.

  When it is determined that the SNR is equal to or higher than the predetermined reference value (“YES” in step S132), the control unit 40a determines whether the remaining amount of the battery supplied from the power supply unit 60 is sufficient for positioning ( It is determined whether or not it is possible to acquire the information on OK and the current position (step S133). If it is determined that it is not sufficient (not OK) (“NO” in step S133), the process of the control unit 40a proceeds to step S141. If it is determined to be sufficient (“YES” in step S133), the process of the control unit 40a proceeds to step S126.

FIG. 6 is a flowchart showing a modified example 3 of the function selection control process.
In the function selection control process of the third modification, the processes of steps S131 to S133 and S141 are added to the function selection control process shown in FIG. 3, and the processes of steps S107, S108, S124 and S125 are omitted. ing. The other processing contents are the same. Further, the processes of steps S131 to S133 and S141 performed in place of the processes of steps S124 and S125 are the same as those shown in the modified example 2, and thus the description thereof will be omitted.

As described above, the electronic timepiece 1 according to the present embodiment wirelessly establishes a communication connection between the satellite radio wave reception processing unit 54 that receives the broadcast radio wave including date and time information and the external device in which the identification information 421 is set. A communication unit 55 that performs communication, a control unit 40a (CPU 41 and RAM 42), and an operation reception unit 52 that receives an input operation via operation members (push button switches B1, B2 and crown C1) are provided. The control unit 40a (CPU 41) receives the current date / time information from the set external device via the communication unit 55 when the long press operation corresponding to the current date / time information acquisition command is accepted via the push button switch B1. From the first information acquisition operation to acquire and the second information acquisition operation to acquire information based on the broadcast radio wave from the positioning satellite received by the satellite radio wave reception processing unit 54, the identification information 421 of the external device is obtained. Select according to whether or not there is a setting.
In this way, when the setting is not made according to the presence / absence of the setting of the identification information 421, the operation acceptance operation related to the information acquisition from the external device is omitted from the beginning, so the user does not know at what stage the operation is currently performed. It is possible to skip the unnecessary judgment as to whether or not there is any stress and to reach the acceptance state of the desired operation more efficiently without stress. Further, when the identification information 421 is set, normally, the date and time can be acquired from the external device in a short time and with low power consumption, so that the date and time correction operation by the user becomes easier.
Therefore, the electronic timepiece 1 can acquire date and time information more flexibly and efficiently.

  In addition, the control unit 40a selects the second information when the duration of the pressed state of the push button switch B1 is 2 seconds (first reference time) or more after selecting the first information acquisition operation. Change the selection to get action. In this way, even when connected to an external device such as a smartphone, if there is a reason such as being out of hand or being in an unusable state, promptly receive the radio wave from the positioning satellite and receive the electronic watch. Since the date and time information can be acquired independently by one, the user can easily and flexibly switch the acquisition target of the date and time information according to the situation while basically receiving from the external device. Further, in this case, the user simply needs to continue to press the push button switch B1, which facilitates the operation to be remembered.

  Further, when the pressing operation of the push button switch B1 is detected again within a predetermined time after selecting the first information acquisition operation, the control unit 40a changes the selection to the second information acquisition operation. As described above, since it is possible to easily switch to the reception of radio waves from the positioning satellite by an additional operation after the operation of the communication unit 55 is started, the processing does not become complicated. Moreover, since the reception target can be switched by operating only the single push button switch B1, the user operation is not complicated.

  In addition, in the first information acquisition operation, information related to the current time and information related to the current position are acquired. As described above, if the identification information 421 is set, the date and time information and the current position information can be acquired together in a short time by an easy operation, so that the radio wave reception from the positioning satellite is performed. Normally, it is possible to easily obtain the information necessary for displaying the accurate date and time including the local time setting, etc., while leaving the operation in a range that does not complicate the operation.

In addition, the radio wave reception unit includes a satellite radio wave reception processing unit 54 that receives a radio wave from a positioning satellite.
By making it possible to acquire date and time information and current position information using radio waves from positioning satellites, the electronic timepiece 1 can count and display accurate dates and times around the world even when external devices such as smartphones cannot be used. it can.

  In addition, after selecting the second information acquisition operation, if the pressing operation of the push button switch B1 is detected again within the time until the date and time acquisition, the control unit 40a performs the positioning operation and changes the current time. Get information and information about current location. When the acquisition of the date and time information is switched to the acquisition including the current position information when the identification information 421 of the external device is not set, it suffices to simply press the push button switch B1 once more. Does not become complicated and does not significantly increase the user's labor.

  Further, when the second information acquisition operation is selected, the control unit 40a determines whether or not the positioning operation is possible based on the remaining amount of the battery that supplies power to the satellite radio wave reception processing unit 54. That is, it is possible to prevent the positioning operation from being started when there is not enough battery power remaining to perform the positioning operation. Therefore, in the electronic timepiece 1, efficient information acquisition is performed while avoiding wasteful power consumption and increase in user waiting time.

  In addition, when the second information acquisition operation is selected, the control unit 40a operates the satellite radio wave reception processing unit 54 and based on at least one of the number of positioning satellites captured by the satellite radio wave reception processing unit 54 and the SNR. Then, it is determined whether or not the positioning operation is possible. That is, when the environment is not such that positioning can be performed easily and reliably, the electronic timepiece 1 can be prevented from performing positioning operation. Therefore, in the electronic timepiece 1, efficient information acquisition is performed while avoiding wasteful power consumption and increase in user waiting time.

  Further, the hands 11 to 14 (in particular, the second hand 13) for displaying the type of the information acquisition operation selected based on the control of the control unit 40a are provided. With this, in the electronic timepiece 1, it is possible to easily inform the user which operation is being performed.

In addition, the information acquisition control method of the present embodiment allows the external device set in the identification information 421 to be transmitted from the external device when the long press operation corresponding to the information acquisition command related to the current time is received via the push button switch B1. From the first information acquisition operation of acquiring information via the communication unit 55 and the second information acquisition operation of acquiring information based on the broadcast radio wave received by the satellite radio wave reception processing unit 54, the external device It includes an operation selecting step of selecting and acquiring information according to the presence or absence of setting.
In this way, by selecting the information acquisition destination according to whether or not the identification information 421 is set, when the identification information 421 is set, the date and time can be obtained from an external device that can easily obtain the necessary information in a short time. When the information is acquired and the identification information 421 is not set, the date and time information is acquired by receiving the broadcast wave that can obtain the same information by itself without using an external device. Therefore, it is possible to acquire the date and time information more easily and efficiently while avoiding causing the user to perform complicated processing, requiring unnecessary waiting time, and consuming power.

In addition, the program 511 of the present embodiment causes the computer (control unit 40a) of the electronic timepiece 1 to receive a long press operation corresponding to an instruction to acquire information about the current time via the push button switch B1. A first information acquisition operation of acquiring information from the external device set in the identification information 421 via the communication unit 55, and information is acquired based on the broadcast radio wave from the positioning satellite received by the satellite radio wave reception processing unit 54. From the second information acquisition operation to be performed, it functions as an operation selection unit that selects according to whether or not the identification information 421 related to the external device is set.
By installing such a program 511 and performing operation control by software to efficiently obtain date and time information, it is possible to easily obtain date and time information without complicating the circuit scale and the like in the electronic timepiece 1. Efficient control can be performed.

Further, one device may be a communication connection partner by Bluetooth, and the other device may be a communication connection destination by another communication means such as a wireless LAN. If none is set, radio waves are received from positioning satellites.

  Further, in the above-described embodiment, when the information is acquired from the external device by Bluetooth via the communication unit 55, the current position information is always acquired together with the date / time information, but the current position information is not necessarily acquired at the same time. There is no. It may not be acquired, or even if the selection is changed so as to acquire date and time information in accordance with the pressed state of the push button switch B1 as well as the transition from the date and time acquisition by the satellite radio wave reception processing unit 54 to the positioning operation. good.
