FIG. 5 is a diagram showing another display example of the first term zone according to the present embodiment.
In the example shown in FIG. 2, an example is shown in which the main clock indicates the first time zone. However, since the time is not displayed in 24 hours, whether the displayed time is AM (AM) or PM (PM ) Is determined by the user. Therefore, in the example shown in FIG. 5, the second hand 120A indicates whether it is AM (morning) or PM (afternoon). Note that the display shown in FIG. 5 is switched to the display of FIG. 5 after a predetermined time of the display of FIG. 2, or the display of FIG. 2 is switched to the display of FIG. 5 when any of the push buttons 104b to 104d is pressed.

The relationship between the time displayed on the main clock and the small clock shown in FIGS. 2 to 6 will be further described.
FIG. 7 is a diagram illustrating an example of the relationship between the main clock and the time displayed on the small clock by the operation of the input unit 104 of the clock 100 according to the present embodiment. The relationship shown in FIG. 7 is stored in the storage unit 105.

  In the example shown in FIG. 7, the first time zone has a time difference of −5 hours from Coordinated Universal Time (UTC), and daylight saving time (DST) is also set. Next, the date and time to switch to daylight saving time are not set next. In the second time zone, the time difference from Coordinated Universal Time is 0 hour, daylight saving time is not set, and the date and time to switch to daylight saving time next is not set. In the third time zone, the time difference from Coordinated Universal Time is +1 hour, daylight saving time is not set, and the date and time to switch to daylight saving time next is not set.

Also, the time displayed on the small clock has a time difference of +9 hours from Coordinated Universal Time, no daylight saving time is set, and no date and time to switch to daylight saving time next is set.
Such setting is performed by the user operating the input unit 104. The information processing unit 1014 causes the input unit 104 to store each setting in the storage unit 105 according to the operation result.

Next, an example of setting the time displayed on the main clock and the small clock by the communication device 200 will be described.
FIG. 8 is a diagram illustrating an example of an application screen for setting a time zone that operates on the communication device 200 according to the present embodiment.

The example illustrated in FIG. 8 is an example of a setting screen displayed on the display unit 203 after an application for setting a time zone is started on the communication device 200.
The area g1 is an area for displaying a world map. The area g2 is an area for setting each main clock. The area g3 is an area for setting each small clock. The transmission button image g4 is an image of a button for transmitting the set information to the clock 100.

An example of the setting method will be described with reference to FIGS.
FIG. 9 is a diagram illustrating an example of the relationship between the time displayed on the main clock and the small clock by the operation of the communication device 200 according to the present embodiment.
The user taps and selects, for example, the button image g21 for setting the first time zone in the region g2. Then, the user selects the city to be set as the first time zone by tapping the world map image in the region g1. In the world map image, the city name or country name corresponding to the tapped position may be displayed in the region g1 or outside the region g1.

  In the example shown in FIGS. 8 and 9, New York is selected as the first time zone (TIME1). For this reason, the time difference from Coordinated Universal Time is -5 hours. Since New York is not in daylight saving time at the set date and time, the setting for daylight saving time is in the off state (OFF), and the date and time to switch to daylight saving time next is 2:00 am on March 12, 2017 by adding +1 hour An instruction to switch to daylight saving time is set by this selection.

  Similarly, as the second time zone (TIME2), the region g22 and the region g1 are tapped to select London, and as the third time zone (TIME3), the region g23 and the region g1 are tapped to Paris. Is selected, and the setting shown in FIG. 9 is performed according to the selected result.

  Furthermore, in order to set the time to be displayed on the small clock when the first time zone is displayed, the user taps the button image g31 for performing setting corresponding to the first of the small clock in the region g2, for example. select. When setting from the communication device 200, the time of the region or country displayed on the small clock can be set for each time zone. The user selects the city to be set first by tapping the world map image in the region g1. In the example shown in FIGS. 8 and 9, Tokyo is selected. For this reason, the time difference from Coordinated Universal Time is +9 hours. Since there is no daylight saving time in Tokyo, the setting for daylight saving time is in the off state (OFF), and the date and time for switching to daylight saving time next is also set to null.

  Similarly, as the second setting, the area g32 and the area g1 are tapped to select Tokyo, and as the third setting, the area g33 and the area g1 are tapped to select Tokyo, and the result of the selection is selected. In response to this, the setting shown in FIG. 9 is performed. When the settings of the areas g31 to g33 are the same, for example, the user may tap the area of the small clock setting g34 so that the settings of the areas g31 to g33 can be set collectively in the same manner. .

The user selects the transmission button image g4 after setting. The control unit 201 detects that the transmission button image g4 has been selected, and transmits the setting content described above to the timepiece 100.
The information processing unit 1014 of the watch 100 stores the information received from the communication device 200 in the storage unit 105.

  In the example illustrated in FIG. 8, the example in which the first time zone is set is described, but the present invention is not limited to this. The setting of the first time zone may be in accordance with the time zone in which the communication device 200 is currently used. In this case, the communication device 200 may set a time difference from the coordinated universal time in accordance with the position information obtained via the network. Alternatively, the small clock setting may be in accordance with the time zone in which the communication device 200 is currently used.

  In the example shown in FIG. 8, an example in which the main clock and the small clock of the timepiece 100 are set on the communication device 200 side is shown. However, on the communication device 200 side, the start and end of the chronograph, alarm, timer, etc. An instruction may be given.

<Time zone setting>
Next, a time zone setting process procedure by the input unit 104 of the timepiece 100 will be described.
FIG. 10 is a flowchart of time zone setting processing by the input unit 104 of the timepiece 100 according to the present embodiment.

  (Step S601) The user operates the input unit 104 to select a time zone to be set. The input unit 104 detects a result operated by the user and outputs the detected operation result to the information processing unit 1014.

  (Step S602) The information processing unit 1014 acquires the operation result output by the input unit 104. Subsequently, the information processing unit 1014 determines whether the setting mode is TIME1 or another setting mode. If the information processing unit 1014 determines that the setting mode is TIME1 (step S602; YES), the information processing unit 1014 proceeds to step S603. If the information processing unit 1014 determines that the setting mode is another setting mode (step S602; NO), the processing proceeds to step S605. Proceed with the process.

(Step S <b> 603) The information processing unit 1014 stores the setting of the main clock of TIME 1 in the storage unit 105.
(Step S <b> 604) The information processing unit 1014 stores the setting of the small clock in the storage unit 105. The information processing unit 1014 ends the time zone setting processing after the processing.

  (Step S605) The information processing unit 1014 determines whether the setting mode is TIME2 or another setting mode. If the information processing unit 1014 determines that the setting mode is TIME2 (step S605; YES), the information processing unit 1014 proceeds to step S606. If the information processing unit 1014 determines that the setting mode is another setting mode (step S605; NO), the processing proceeds to step S608. Proceed with the process.

  (Step S606) The information processing unit 1014 stores the setting of the main clock of TIME2 in the storage unit 105. The information processing unit 1014 ends the time zone setting processing after the processing.

  (Step S607) The information processing unit 1014 determines whether the setting mode is TIME3 or another setting mode. If the information processing unit 1014 determines that the setting mode is TIME3 (step S607; YES), the information processing unit 1014 proceeds to step S608 and determines that the setting mode is another setting mode (step S607; NO). The setting process ends.

  (Step S608) The information processing unit 1014 stores the setting of the main clock of TIME3 in the storage unit 105. The information processing unit 1014 ends the time zone setting processing after the processing.

In the example illustrated in FIG. 10, the example in which the small clock is set when TIME 1 is set is described, but the present invention is not limited to this. The setting of the small clock may be performed by at least one of TIME1, TIME2, and TIME3.
In the example illustrated in FIG. 10, the example in which the time zone is set on the watch 100 side has been described. However, when information set on the communication device 200 side is received as illustrated in FIG. Step 1014 performs the processing after step S602 after reception. In this case, the information processing unit 1014 may store the setting of the small clock in the storage unit 105 for each time zone.

<Process when set by clock>
Next, a processing procedure performed by the control unit 101 when set by the input unit 104 of the timepiece 100 will be described.
11 and 12 are flowcharts of processing performed by the control unit 101 when set by the input unit 104 of the timepiece 100 according to the present embodiment. In the following description, the operation modes are the time display operation (TIME1) in the first time zone, the time display operation (TIME2) in the second time zone, the time display operation (TIME3) in the third time zone, It is assumed that the operation is chronograph operation (CHR), alarm operation (ALM), and timer operation (TMR).

  (Step S1) The user selects an operation mode to be set from operation modes displayed by rotating the crown 104a of the input unit 104. Thereby, the user can visually recognize the operation mode to be selected. The input unit 104 detects a result operated by the user and outputs the detected operation result to the information processing unit 1014.

  (Step S <b> 2) The information processing unit 1014 acquires the operation result output from the input unit 104. Subsequently, the information processing unit 1014 determines whether the operation mode is TIME1 or another operation mode. If the information processing unit 1014 determines that the operation mode is TIME1 (step S2; YES), the information processing unit 1014 advances the process to step S3, and determines that the operation mode is another operation mode (step S2; NO), step S5. Proceed with the process.

(Step S3) The information processing unit 1014 reads the setting of the main clock of TIME1 stored in the storage unit 105.
(Step S <b> 4) The information processing unit 1014 reads the setting of the TIME1 small clock stored in the storage unit 105. After the process, the information processing unit 1014 proceeds to the process of step S12 (FIG. 12).

  (Step S5) The information processing unit 1014 determines whether the operation mode is TIME2 or another operation mode. If the information processing unit 1014 determines that the operation mode is TIME2 (step S5; YES), the information processing unit 1014 proceeds to step S6. If the information processing unit 1014 determines that the operation mode is another operation mode (step S5; NO), the information processing unit 1014 proceeds to step S8. Proceed with the process.

(Step S6) The information processing unit 1014 reads the setting of the TIME2 main clock stored in the storage unit 105.
(Step S7) The information processing unit 1014 reads the setting of the TIME2 small clock stored in the storage unit 105. After the process, the information processing unit 1014 proceeds to the process of step S12 (FIG. 12).

  (Step S8) The information processing unit 1014 determines whether the operation mode is TIME3 or another operation mode. If the information processing unit 1014 determines that the operation mode is TIME3 (step S8; YES), the information processing unit 1014 advances the process to step S9. If the information processing unit 1014 determines that the operation mode is another operation mode (step S8; NO), the information processing unit 1014 proceeds to step S11. Proceed with the process.

(Step S9) The information processing unit 1014 reads the setting of the main clock of TIME3 stored in the storage unit 105.
(Step S10) The information processing unit 1014 reads the setting of the TIME3 small clock stored in the storage unit 105. The information processing unit 1014 outputs the read information to the pointer control unit 1016, and then proceeds to the process of step S12 (FIG. 12).

  (Step S11) The information processing unit 1014 performs processing according to each of the other operation modes (CHR, ALM, TMR). Note that the processing corresponding to each operation mode (CHR, ALM, TMR) means the drive target value of the pointer 120 for each operation mode, the driving of the pointer 120, the function assignment to the push buttons 104b to 104d, and the crown 104a being pulled back. Function setting at the time of setting, setting at the time of combination not existing in mode switch combination (setting at the time of non-existence mode switch combination), and the like. After the processing, the information processing unit 1014 terminates the processing when set by the input unit 104.

Turning to FIG. 12, the description of the processing is continued.
(Step S12) The pointer control unit 1016 sets a designated position based on the city, time difference, and time zone of the main clock as the drive target value of the second hand 120A. The designated position is indicated by the number of drive pulses up to the designated position when LON (0 second position) is used as the reference position. Specifically, the pointer control unit 1016 calculates the time of the selected time zone based on the time difference of the selected operation mode, and sets the indicated position based on the calculated position.

  (Step S13) The pointer control unit 1016 sets a drive target value based on the setting of the main clock in each of the minute hand 120B, the hour hand 120C, and the date indicator 120E. The drive target value includes the designated position and the number of drive pulses by forward rotation.

  (Step S14) The pointer control unit 1016 reads the setting of the small clock stored in the storage unit 105. Subsequently, the pointer control unit 1016 sets a drive target value based on the setting of the small clock. The drive target value includes the designated position and the number of drive pulses by forward rotation.

  (Step S15) The pointer control unit 1016 generates a drive pulse based on each drive target value. The pointer control unit 1016 drives each of the pointers 120 by the generated driving pulse (hereinafter referred to as a pointer driving process). The pointer driving process will be described later.

  (Step S16) The pointer control unit 1016 determines whether all the pointers 120 for which the drive target value has been set have reached the target value and a predetermined time has elapsed. When it is determined that all the pointers 120 that have set the drive target value have not reached the target value or the predetermined time has not elapsed (step S16; NO), the pointer control unit 1016 performs the process of step S16. repeat. The pointer control unit 1016 determines that all the pointers 120 for which the drive target value has been set have reached the target value and that a predetermined time (for example, 5 seconds) has elapsed from the time corresponding to the target value (step S16; YES), the process proceeds to step S17.

  (Step S17) The pointer control unit 1016 resets the target drive value of the second hand 120A to a value corresponding to the second of the current time.

  (Step S18) The pointer control unit 1016 drives the second hand 120A (pointer driving process). After the process, the control unit 101 ends the process when set by the input unit 104.

Next, step S15 and step S18 in FIG. 12 will be further described.
FIG. 13 is a flowchart of the pointer driving process according to the present embodiment.
(Step S101) The pointer control unit 1016 calculates each drive pulse from the difference between the current position of the second hand 120A and the drive target value for each second hand 120A in all second hands 120A for which the drive target value is set. Note that the drive target value with respect to time is separately updated by a time measurement process performed by the time count unit 1012.

  (Step S102) The pointer control unit 1016 determines whether to move the second hand 120A forward to the target position or reversely to move based on the driving time. Subsequently, the pointer control unit 1016 corrects the number of drive pulses when the rotation direction is reverse based on the determined result. In the correction of the number of drive pulses, for example, a value that was 50 in the forward rotation is corrected to 10 (= 60-50) in the reverse rotation.

(Step S103) The pointer control unit 1016 starts driving the pointer 120 by generating drive pulses of the calculated number of drive pulses and supplying them to the motor 122 one by one. In addition, when performing reverse rotation, the pointer control unit 1016 appropriately performs correction driving for backlash with respect to the play between the gears included in the train wheel.
(Step S104) The pointer control unit 1016 updates the position of the pointer 120 (pointer position) every time the pointer 120 is driven by one pulse.

  (Step S105) The pointer control unit 1016 determines whether all the pointers 120 for which the drive target value has been set have reached the drive target value, that is, whether or not the target drive pulse has been driven. If the pointer control unit 1016 determines that all the pointers 120 that have set the drive target value have not reached the drive target value (step S105; NO), the process returns to step S103. If the pointer control unit 1016 determines that all the pointers 120 for which the drive target value has been set have reached the drive target value (step S105; YES), the pointer drive process is terminated.

Here, the reason why determination is made based on the time required for driving in step S102 will be described.
Depending on the position at which the pointer 120 is moved, it may be faster to move it backward than to move it forward. Further, since the motor 122 is a stepping motor, the time required for normal rotation may be shorter than the time required for reverse rotation. For example, when the second hand 120A is moved from the 0 second position to the 31 second position, the number of drive pulses is 31 for forward rotation and 29 for reverse rotation. However, as described above, one reverse rotation pulse takes longer than one normal rotation pulse, and in this case, the normal rotation time is shorter. As described above, the pointer control unit 1016 may determine whether to perform forward rotation or reverse rotation from the time required for driving.

<Communication between watch 100 and communication device 200>
The processing described in FIGS. 11 to 13 has been described as an example of processing when the input unit 104 of the timepiece 100 is operated by the user.
Next, an example of a processing procedure when the watch 100 communicates with the communication device 200 and drives the hands 120 based on the communication result will be described. In the following description, an example will be described in which the timepiece 100 and the communication device 200 communicate using the BLE communication standard. Further, before the start of the following processing, that is, when the timepiece 100 is not communicating with the communication device 200, the control unit 101 stops power supply to the wireless communication control unit 111, thereby reducing the power consumption of the timepiece 100. Is reduced.
FIG. 14 is a flowchart of processing of the timepiece 100 in communication with the communication device 200 according to the present embodiment.

  First, as described with reference to FIG. 8, the user operates the communication device 200 to operate the application so that the setting is transmitted to the clock 100. Subsequently, the communication device 200 starts transmitting information to the clock 100.

  (Step S201) The user operates the input unit 104 of the timepiece 100 to select a state for receiving. Subsequently, based on the operation of the input unit 104, the communication control unit 1013 determines whether communication is started or whether an operation for starting communication is performed. If the communication control unit 1013 determines that communication has not started (step S201; NO), the process of step S201 is repeated. If the communication control unit 1013 determines that communication has started (step S201; YES), the communication control unit 1013 proceeds to the process of step S202.

(Step S <b> 202) The communication control unit 1013 outputs information indicating that communication has started to the power supply control unit 1011. Subsequently, the power supply control unit 1011 controls the power supply to the wireless communication control unit 111 to start (ON state).
(Step S203) The communication control unit 1013 determines whether the activation of the wireless communication control unit 111 has been completed. If the communication control unit 1013 determines that activation of the wireless communication control unit 111 has not been completed (step S203; NO), the communication control unit 1013 repeats the process of step S203. If the communication control unit 1013 determines that activation of the wireless communication control unit 111 has been completed (step S203; YES), the communication control unit 1013 proceeds to the process of step S204. Note that the communication control unit 1013 determines whether or not the wireless communication control unit 111 has been activated, for example, based on whether or not the voltage value of a predetermined terminal of the wireless communication control unit 111 is greater than or equal to a threshold value. A command is transmitted to the unit 111, and a determination is made based on whether or not there is a response to the transmitted command.

  (Step S <b> 204) The communication control unit 1013 performs settings for starting communication with the wireless communication control unit 111. Subsequently, the communication control unit 1013 controls the wireless communication control unit 111 to start communication with the communication device 200. Note that the communication establishment and communication procedures are based on the BLE communication standard.

  (Step S205) The communication control unit 1013 determines whether communication with the communication device 200 has been established. When it is determined that communication with the communication device 200 has not been established (step S205; NO), the communication control unit 1013 repeats the process of step S205. If the communication control unit 1013 determines that communication with the communication device 200 has been established (step S205; YES), the communication control unit 1013 proceeds to the process of step S206.

(Step S <b> 205) The communication control unit 1013 transmits information indicating that preparation for starting communication has been completed to the communication device 200.
Hereinafter, the clock 100 transmits and receives information to and from the communication device 200.

Next, an example of a processing procedure when information is received from the communication device 200 will be described.
FIG. 15 is a flowchart of processing when information is received from the communication device 200 according to the present embodiment.

  (Step S301) The information processing unit 1014 determines whether or not the received information includes an instruction (command) related to the time setting of the TIME1, TIME2, and TIME2 main clocks and the setting of the small clock. If the information processing unit 1014 determines that there is no command (step S301; NO), the information processing unit 1014 repeats the process of step S301. If the information processing unit 1014 determines that the above-described command is present (step S301; YES), the information processing unit 1014 proceeds to the process of step S302.

  (Step S302) The information processing unit 1014 updates the time settings of the TIME1, TIME2, and TIME2 main clocks and the settings of the small clocks stored in the storage unit 105. The information processing unit 1014 ends the process after the update.

Next, an example of a processing procedure when ending communication with the communication device 200 will be described.
FIG. 16 is a flowchart of processing when communication with the communication device 200 according to the present embodiment is terminated.

  (Step S401) The communication control unit 1013 determines whether or not there is a communication disconnection request from the communication device 200. If the communication control unit 1013 determines that there is no communication disconnection request (step S401; NO), the process of step S401 is repeated. If the communication control unit 1013 determines that there is a communication disconnection request (step S401; YES), the communication control unit 1013 proceeds to the process of step S402.

(Step S402) The communication control unit 1013 controls the power supply to the wireless communication control unit 111 to be stopped (OFF) after the communication with the communication device 200 is completed.
This completes the communication with the communication device 200.

FIG. 17 is a flowchart of time display return processing after communication with the communication device 200 according to the present embodiment is completed.
(Step S501) The information processing unit 1014 performs the operation mode switching process described with reference to FIGS. 11 and 12 after the communication with the communication device 200 is completed.

  In the above-described example, the example of switching and displaying the time of three countries and regions (three time zones) has been described. However, the number of time zones to be switched and displayed may be four or more. In this case, for example, the third dial 72c has a display of TIME1 to TIME4, and the instruction pointer 120F indicates any one of TIME1 to TIME4, and the time of each time zone may be displayed as described above. .

  As described above, according to the present embodiment, three or more display modes (display modes) in which the city / time zone of the time displayed on the timepiece 100 can be arbitrarily set are provided and can be switched by the operation member. That is, according to the present embodiment, the same hour / minute / second hand can be switched to three or more time displays by operating the input unit 104. The timepiece 100 according to the present embodiment can be reduced in size as compared with a timepiece that displays three times on a single dial at the same time, for example.

  In addition, according to the present embodiment, a small clock having a display area smaller than that of the main clock is provided, and the small clock can indicate a time independent of the main clock in the display mode. That is, according to the present embodiment, it is possible to realize the pointer-type timepiece 100 that can switch the time of the main clock to three or more while keeping the time displayed on the small timepiece. For example, the time of the city where you mainly live, which is so-called home time, can be displayed on the small clock, and the time of the city such as the time of a business partner, a travel destination, or the current location can be displayed on the main clock.

  In addition, according to the present embodiment, the third dial 72c is provided with a scale (third dial 72c) indicating the types of three display modes (display modes) and the indication pointer 120F, and the operation of the input unit 104 is performed. Can indicate the type of the display mode (display mode) that is currently displayed. The types are TIME1, TIME12, and TIME3. Note that the type stamped on the third dial 72c is not limited to this, and may be TIME ZONE1, TIME ZONE2,. That is, according to the present embodiment, it is possible to display three or more different times, and in a watch that can display two times on one dial, three or more types are displayed with a pointer. The correspondence between the guideline and the time zone can be changed.

In addition, according to the present embodiment, when the operation mode is switched, the second hand 120A, which is a part of the pointer 120 for displaying the time, temporarily displays information related to the time zone displayed by the pointer, and then the time is displayed. Therefore, the timepiece 100 can be downsized.
Here, the information displayed once by the second hand 120A is city information or time zone information. Also, the information displayed once by the second hand 120A is AM / PM information.

  Further, according to the present embodiment, one time of the main clock is a time according to the location of the communication device 200, and the other time can be a fixed city (time zone) time.

  In this embodiment, since three cities are selected and stored in the clock 100 in advance, the user finds and selects a desired city from a number of cities when he / she wants to know the time of each city. Since the time of each city can be known by simply switching the operation mode without performing a complicated operation, convenience is improved. In this way, for example, convenience is improved by setting in advance times corresponding to three or more frequently used cities and time zones. For example, in the conventional timepiece, when a city is selected, for example, when twenty countries are registered in the timepiece, it is necessary to select the city by operating the operation unit up to twenty times. Furthermore, when it is desired to know the times of the two cities, it was necessary to repeat these operations. On the other hand, according to this embodiment, by operating the input unit 104 several times, it is possible to know the times of a plurality of cities that have been set. In addition, according to the present embodiment, for example, the mode of each city can be switched by rotating the wristwatch such as the above-mentioned crown, etc., in other words, without impairing the operation feeling of the conventional wristwatch, in other words, Each time can be set easily while maintaining the operational feeling of the wristwatch. Therefore, the convenience at the time of setting each city time with a wristwatch improves.
