[0008] An electronic timepiece 1 according to an embodiment of the invention will now be described with reference to the drawings. As shown in FIG. 1, the electronic watch 1 is a diver's watch worn on the user's wrist, and includes an outer case 2, a dial 3, a rotating bezel 4, a movement (not shown), and hands including a second hand 5, a minute hand 6, an hour hand 7, a date wheel 8, a crown 11, and a button 12. The dial 3 has a scale divided into 60 parts, with the word "YES" written on the inner circumference of the 10-second scale, which is the first position indicated by the second hand 5, the word "NO" written on the inner circumference of the 20-second scale, which is the second position, and the word "OFF" written on the inner circumference of the 30-second scale, which is the third position. The rotating bezel 4 also has a scale divided into 60 parts.

[0009] As shown in FIG. 2, the electronic watch 1 includes an operation unit 10, a control device 20, a receiving circuit 40, and a display unit 50. The operating unit 10 is configured with a crown 11 and a button 12. The crown 11 can be moved to a 0 position, a 1 position, and a 2 position. The 0 position is the state in which the crown 11 is pushed all the way into the movement, and the 1 position and the 2nd position are states in which the crown 11 is pulled out to different positions. In this embodiment, when the crown 11 is in the 0 position, a time display mode in which the time is displayed by a hand is executed.

[0010] The receiving circuit 40 includes a receiving section 41 that receives radio waves using an antenna 42. In this embodiment, the radio waves received by the antenna 42 are standard radio waves. The display unit 50 includes a second hand 5, a minute hand 6, an hour hand 7, a date wheel 8, and a wheel train and a stepping motor that drive these. In this embodiment, the display unit 50 includes a second wheel train and a second motor that drive the second hand 5, an hour / minute wheel train and an hour / minute motor that drive the minute hand 6 and the hour hand 7, and a date wheel train and date motor that drive the date wheel 8.

[0011] As shown in FIG. 2, the control device 20 includes a reception control unit 21, a timing unit 22, a storage unit 23, a time correction unit 24, and a display control unit 25. The reception control unit 21 controls the reception circuit 40 to perform radio wave reception processing. The timekeeping unit 22 includes a quartz oscillator and keeps track of the internal time using a reference signal based on an oscillation signal of the quartz oscillator. The memory unit 23 stores reception result data indicating whether radio wave reception was successful or not, reception time data obtained during radio wave reception, internal time data kept by the timing unit 22, and data indicating whether a reception permission state that allows radio wave reception is set or a reception prohibition state that prohibits radio wave reception is set, etc. The time correction unit 24 corrects the internal time data stored in the memory unit 23 when radio waves are received to obtain received time data, when the time difference is manually corrected, or when the time or date is manually corrected. The display control unit 25 controls the display unit 50 according to the internal time data, and displays the internal time using the second hand 5, minute hand 6, hour hand 7, and date wheel 8. In the reception result display mode, the reception result and reception prohibited status are displayed using the second hand 5, which is one of the multiple hands that display the time.

[0012] In this embodiment, the hands are not limited to the second hand 5, minute hand 6, and hour hand 7, but also include disc-shaped members such as the date wheel 8 and day wheel. Furthermore, the hands are not limited to those that display the time, but also include members that are driven by a stepping motor, such as a mode hand and an indicator hand, and indicate various information and states.

[0013] [Reception result display mode] Next, the control by the control device 20 when the first operation, ie, the reception result display operation, is performed on the electronic timepiece 1 will be described with reference to the flow chart in FIG. 3 and the operation explanatory diagram in FIG. When the crown 11 is in the 0 position, a time display mode in which the time is displayed by hands is executed, and when the button 12 is pressed for a short time, for example for less than three seconds, in this time display mode, the reception result display mode is executed. Therefore, the first operation is the operation of pressing the button 12 with the crown 11 in the 0 position. As shown in FIG. 3, when the control device 20 executes step S11 in the time display mode and detects that the button 12 has been pressed and released within three seconds to perform the first operation, the reception control unit 21 executes step S12 and determines whether or not the reception is set to a prohibited state. If the reception control unit 21 judges NO at step S12, it executes step S13 and refers to the reception result data in the storage unit 23 to judge whether the result of the immediately preceding reception was successful.

[0014] If the reception control unit 21 judges the result to be YES in step S13, it executes step S14, in which it uses the display control unit 25 to move the second hand 5 to the "YES" position indicating a successful reception, that is, the first position, the 10-second position. That is, as shown in Figure 4, the mode switches from the time display mode shown in S100 to the reception result display mode shown in S110, and the second hand 5 is fast-forwarded clockwise from the currently indicated position and stops at the 10-second position, that is, the YES position. If the reception control unit 21 judges the result in step S13 to be NO, it executes step S15, which causes the display control unit 25 to move the seconds hand 5 to the "NO" position, which indicates a reception failure, i.e., the second position, the 20-second position. Then, as shown in S120 in Figure 4, the seconds hand 5 is fast-forwarded clockwise from the currently indicated position and stops at the 20-second position, i.e., the NO position. The reception control unit 21 is set to the reception prohibited state, and if it judges YES in step S12, it executes step S16, which causes the display control unit 25 to move the second hand 5 to the "OFF" position, which indicates reception prohibited, i.e., the third position, the 30-second position. Then, as shown in S130 in Figure 4, the second hand 5 is fast-forwarded clockwise from the current indicated position and stops at the 30-second position, i.e., the OFF position.

[0015] The reception result display mode is released manually, specifically when button 12 is pressed again. It is also automatically released five seconds after the reception result display starts. When the reception result display mode is released, the mode returns to the time display mode. For this reason, the display control unit 25 fast-forwards the second hand 5 to a position indicating the current second measured by the timing unit 22, and thereafter the second hand 5 indicates the current second.

[0016] [Automatic reception mode] Next, the control by the control device 20 when the automatic reception mode is executed in the electronic timepiece 1 will be described using the flow chart in FIG. When the internal time kept by the timer 22 reaches the automatic reception start time and step S21 is executed, the reception control unit 21 of the control device 20 executes step S22, in which the memory unit 23 is referenced to determine whether reception is set to a prohibited state. The reception prohibited state is a state in which reception is not performed even if the conditions for starting automatic reception or manual reception are met. In other words, it is a state in which radio wave reception is prohibited. Note that the automatic reception start time is set to a time such as 2:00 a.m. when there is little influence from other radio waves in an electronic watch 1 that receives standard radio waves, for example. Also, in this embodiment, the automatic reception condition for executing the automatic reception process is that the internal time reaches the automatic reception start time, but other conditions may be set as the automatic reception condition, such as power generation by a solar cell if the electronic watch 1 is equipped with a solar cell. If the reception control unit 21 judges NO in step S22, that is, if the reception is not set to a reception prohibited state but is set to a reception permitted state in which reception is permitted, it executes step S23 and operates the receiving circuit 40 to perform reception. Next, the reception control unit 21 executes step S24 to determine whether the reception was successful or not, and if the reception was successful, that is, if the determination is YES in step S24, it executes step S25 to change the reception result data in the memory unit 23 to success.

[0017] On the other hand, if the reception control unit 21 judges YES in step S22, i.e., if reception is set to a prohibited state, or if the reception control unit 21 judges NO in step S24, i.e., if reception has failed, it executes step S26 and changes the reception result data in the memory unit 23 to failure. For this reason, when automatic reception is executed in a reception permitted state, the reception control unit 21 updates the reception result data with the result of the executed automatic reception, and when the automatic reception conditions are met in a reception prohibited state, the automatic reception is not executed and the reception result data is set to failure. Therefore, within the automatic reception cycle, for example if automatic reception is performed at 2 am every day, if the reception permitted state is switched to the reception prohibited state between 2 am and 2 am the following day, and if it is switched back to the reception permitted state again, the most recent reception result will be displayed when button 12 is subsequently pressed to execute the reception result display mode. For example, if the most recent reception process was automatic reception, the result of that automatic reception will be displayed, and if the most recent reception process was forced reception, the result of that forced reception will be displayed. On the other hand, if the reception is prohibited across the automatic reception time, for example, if automatic reception is performed at 2:00 a.m. every day, the reception is prohibited before 2:00 a.m. and 2:00 a.m. passes without changing the reception state, and the reception is then switched to permitted. If the reception result display mode is executed, when the automatic reception time arrives in the reception prohibited state, the reception result data will be set to failure, so when the reception result display mode is executed, the second hand 5 will indicate reception failure, in other words, the 20-second position.

[0018] [Forced reception mode] If the electronic watch 1 is in time display mode and reception is permitted, and detects that the button 12 has been pressed for more than 3 seconds but less than 8 seconds, the control device 20 will enter manual reception mode. In manual reception mode, the reception control unit 21 controls the reception circuit 40 to execute reception processing. The reception control unit 21 ends the manual reception mode and returns to the time display mode if reception is successful, if reception is unsuccessful, or if button 12 is pressed again. The reception control unit 21 then stores the reception result data in the memory unit 23.

[0019] [Receive ON / OFF switching mode] When the electronic timepiece 1 is in the time display mode, the control device 20 executes the reception ON / OFF switching mode if the button 12 is pressed and held for 8 seconds or more. That is, the reception ON / OFF switching mode is executed by the second operation of pressing the button 12 for 8 seconds or more with the crown 11 in the 0th position. For this reason, in this embodiment, the first operation and the second operation are the same in that the crown 11 is in the 0th position, and the time for which the button 12 is pressed is different, being less than 3 seconds and 8 seconds or more. If the user presses button 12 for eight seconds or more when reception is ON, i.e., when reception is permitted, the control device 20 switches reception to OFF, i.e., when reception is prohibited, and rewrites the data in the memory unit 23. Conversely, if the user presses button 12 for eight seconds or more when reception is OFF, i.e., when reception is prohibited, the control device 20 switches reception to ON, i.e., when reception is permitted, and rewrites the data in the memory unit 23. For example, if the electronic watch 1 is a diver's watch, the user can switch the electronic watch 1 to the reception prohibited state before diving, thereby preventing reception from starting while diving and the hands that display the time from stopping. The process for executing the reception ON / OFF switching mode includes the following two processes depending on the setting of the control device 20. The first setting is a setting in which reception ON / OFF switching is enabled, and the forced reception mode is not started three seconds after starting to press the button 12, even if reception is permitted at the time of pressing the button 12. In this case, the control device 20 does not start the forced reception mode even three seconds after starting to press the button 12, but executes the reception ON / OFF switching mode when the button is pressed for eight seconds or more. The second setting is that when reception ON / OFF switching is enabled and reception is permitted when button 12 is operated, the forced reception mode starts three seconds after button 12 is pressed, and the reception ON / OFF switching mode is executed if button 12 is pressed and continued for eight seconds or more. In this case, the control device 20 starts the forced reception mode three seconds after button 12 is pressed, and stops the forced reception mode and executes the reception ON / OFF switching mode when button 12 is pressed and continued for eight seconds or more. After switching between the reception permitted state and the reception prohibited state, if button 12 is pressed and released, or if five seconds have elapsed, the control device 20 will end the reception ON / OFF switching mode and return to the time display mode.

[0020] [Effects of the embodiment] The electronic watch 1 uses the second hand 5 as both a pointer that indicates the reception result and a pointer that indicates the reception prohibited state, and when the first operation of the operation unit 10 is performed, that is, when the button 12 is pressed for less than three seconds with the crown 11 in the 0 position, the second hand 5 can display either the reception result or the reception prohibited state. Therefore, when the reception prohibited state is set, the second hand 5 points to the OFF position, which indicates the reception prohibited state, that is, the third position, which is the 30 second position, and does not point to the first position, which is the 10 second position, which indicates the reception result, or the second position, which is the 20 second position. This prevents the user of the electronic watch 1 from misunderstanding that the reception process is being performed even though the reception prohibited state is set. The electronic watch 1 indicates the reception result or reception prohibited status with the second hand 5, which is one of the multiple hands that display the time, so the number of hands on the electronic watch can be reduced compared to when it displays the status with a mode hand separate from the hand that displays the time. As a result, the reception prohibited status and reception result can be displayed on a typical three-hand electronic watch 1.

[0021] Since the electronic watch 1 can display the reception result or whether reception is prohibited when the crown 11 is in the 0 position, in cases where a screw-lock crown 11 is used, such as in a diver's watch, the reception result or reception is prohibited can be easily checked without the need to pull out the crown 11, improving usability for the user.

[0022] By performing the second operation of the operating unit 10, i.e., pressing the button 12 for 8 seconds or more with the crown 11 in the 0 position, the user of the electronic watch 1 can set the reception permitted state or reception prohibited state as desired, so that the reception prohibited state can be switched on and off with a simple operation, improving convenience. Furthermore, because the second operation is performed when the crown 11 is in the 0 position, even if a screw-lock crown is used, the reception permitted state and reception prohibited state can be easily switched, further improving usability for the user.

[0023] If the reception prohibition state continues for a long period spanning the automatic reception cycle, time adjustment by reception will not be performed, and so time accuracy may decrease due to oscillation variations in the crystal oscillator, which may cause the displayed time to become inaccurate. For this reason, if the reception prohibition state is released after a time deviation has occurred, and the reception result display shows success, which is the reception result before the reception prohibition state, the user will determine that no time deviation has occurred because reception was successful, but in reality a time deviation has occurred and is outside the guaranteed range of time accuracy, resulting in a contradiction. In contrast to this, in the electronic watch 1 of the embodiment described above, if the automatic reception conditions are met when the reception is prohibited, the reception result is deemed to be a failure, and so when the reception prohibition state is released, the reception result display shows a failure, thereby preventing inconsistencies.

[0024] The first operation and the second operation are distinguished by pressing one button 12 for different periods of time with the crown 11 in the 0 position. For this reason, it is not necessary to provide two or more buttons to distinguish between the operations, or to press the button 12 at different positions on the crown 11, so the number of parts can be reduced, reducing costs, and operability can be improved because there is no need to pull the crown 11 out to the 1st or 2nd position. In particular, in diver's watches, the buttons need to be pressure resistant, which makes the structure complicated, but the number of buttons can be reduced, which reduces the number of parts required for pressure resistance and makes the structure relatively simple.

[0025] [Variations] It should be noted that the present disclosure is not limited to the above-described embodiments, and modifications, improvements, etc. within the scope that can achieve the object of the present disclosure are included in the present disclosure. In the above embodiment, the reception result or reception prohibited status was indicated by the second hand 5, but it may also be indicated by the minute hand 6 or hour hand 7. In other words, it may be indicated by one of the multiple hands that indicate the time: the second hand 5, the minute hand 6, or the hour hand 7. The reception result or reception prohibited status may also be indicated by the date wheel 8. Also, the reception result or reception prohibited status may be displayed with a mode hand other than the hand that displays the time. In this case, the time display can continue even while the reception result or reception prohibited status is displayed. Note that the mode hand may display other information such as the remaining battery level or day of the week when in the normal time display mode, and may display the reception result or reception prohibited status when the first operation is performed. In addition, the letters "YES" at the first position, "NO" at the second position, and "OFF" at the third position are written on the dial 3, but these may be written on the rotating bezel 4, or may not be written on either the dial 3 or the rotating bezel 4. In addition, the first position is the 10-second position, the second position is the 20-second position, and the third position is the 30-second position, but they may be different positions.

[0026] The first operation and the second operation are not limited to the examples of the above embodiment. For example, two buttons may be provided, and when the crown 11 is in the 0th position, pressing one button executes the first operation, and pressing the other button executes the second operation. Also, the first operation and the second operation may be executed by changing the position of the crown 11 and pressing the button 12.

[0027] In the above embodiment, the reception result display mode was executed when the first operation was performed, but the reception result display mode may be executed not only when the first operation is performed, but also when the reception prohibited state is released and switched to the reception permitted state. If the reception result display mode is executed to display the result of the previous reception when the reception prohibition state is released, the user can check the guaranteed status of the accuracy of the time displayed by the electronic watch 1. That is, if the previous reception result shows success when the reception prohibition state is released, the user can be informed that the accuracy of the displayed time is guaranteed, and if failure is displayed, the user can be informed that the accuracy of the displayed time is also low. Therefore, if failure is displayed, the user can improve the accuracy of the displayed time by performing a forced reception operation.

[0028] In the above embodiment, if the automatic reception conditions are met while reception is prohibited, the reception result data is set to failure, but rather than immediately setting it to failure, it may be possible not to set it to failure within a certain period of time since the last successful reception, but to set it to failure if a certain period of time or more, for example, one week or more, has passed. In other words, if the period during which reception is prohibited is a period during which the time accuracy can be guaranteed without correcting the time through reception, there is no need to change the reception result data to failure, so if the period during which the time accuracy can be guaranteed has passed, the user can be more accurately notified of the status of the time accuracy assurance. The electronic watch 1 is not limited to a diver's watch, and may be an electronic watch other than that for divers. Furthermore, the radio waves received by the receiving circuit 40 are not limited to standard radio waves, and may be satellite signals transmitted from GPS (Global Positioning System) satellites, short-range wireless signals, etc., and the receiving unit 41 and antenna 42 may be appropriate for the type of radio waves to be received.

[0029] [Summary of this disclosure] The electronic watch disclosed herein comprises a receiving unit that receives radio waves, hands, an operating unit, a memory unit that stores the reception result of whether reception by the receiving unit was successful or unsuccessful, and a reception control unit that can be switched between a reception permitted state that allows reception by the receiving unit and a reception prohibited state that prohibits reception by the receiving unit, and is characterized in that when a first operation of the operating unit is executed, the hands indicate a first position when the receiving unit is set to the reception permitted state and the reception result stored in the memory unit is successful, indicate a second position when the receiving unit is set to the reception permitted state and the reception result stored in the memory unit is unsuccessful, and indicate a third position when the receiving unit is set to the reception prohibited state. According to the electronic timepiece of the present invention, the hand that displays the reception result and the hand that displays the reception prohibited state are the same hand, and when the first operation of the operating unit is performed, either the reception result or the reception prohibited state is displayed by the hand, so that when the reception prohibited state is set, the reception result is not displayed. This prevents the user of the electronic timepiece from misunderstanding that the reception process is being performed even though the reception prohibited state is set. In other words, when the first operation of the operating unit is performed and the hand displays the reception result, the user can confirm both that the reception permitted state and the result of the most recent reception process, and when the reception prohibited state is displayed, the user can reliably confirm that the reception prohibited state is set, and no misunderstanding occurs.

[0030] In the electronic timepiece of the present disclosure, the hand is preferably one of a plurality of hands that display the time. According to the electronic watch of the present disclosure, the reception result or reception prohibited status can be displayed with one of the multiple hands that display the time, for example the second hand, so the number of hands on the electronic watch can be reduced compared to when a hand other than the hand that displays the time is used.

[0031] In the electronic timepiece of the present disclosure, it is preferable that the operating unit includes a crown and a button, and the first operation is to operate the button with the crown in the 0 position. According to the electronic watch disclosed herein, the reception result and whether reception is prohibited can be displayed when the crown is in position 0. Therefore, in cases where a screw-lock crown is used, such as in a diver's watch, there is no need to pull out the crown, making it easy to check the reception result and whether reception is prohibited, improving usability for the user.

[0032] In the electronic watch disclosed herein, it is preferable that when a second operation of the operating unit is executed in a time display mode in which the time is displayed using multiple hands, the reception control unit transitions to a mode in which the settings of the reception permitted state and the reception prohibited state can be changed. According to the electronic timepiece disclosed herein, by performing the second operation, the user of the electronic timepiece can set the reception permitted state or reception prohibited state as desired, improving convenience.

[0033] In the electronic watch disclosed herein, it is preferable that the operating unit includes a crown and a button, the first operation is pressing the button when the crown is in the 0th position, and the second operation is pressing the button when the crown is in the 0th position, and the first operation and the second operation are performed for different periods of time for pressing the button. According to the electronic watch disclosed herein, the second operation is performed when the crown is in the 0 position, so that even if a screw-lock crown is used, it is possible to easily switch between the reception permitted state and the reception prohibited state, improving usability for the user.

[0034] In the electronic timepiece disclosed herein, after the reception prohibited state is released, it is preferable that the hands indicate the first position or the second position depending on the reception result stored in the memory unit. According to the electronic watch disclosed herein, when the reception inhibition state is released, the previous reception result is displayed, so the user can check the guaranteed state of the time accuracy displayed by the electronic watch. That is, when the reception inhibition state is released and the previous reception result shows "success", the user can be informed that the accuracy of the displayed time is guaranteed, and when "failure" is displayed, the user can be informed that the accuracy of the displayed time is also low. Therefore, when "failure" is displayed, the user can perform a forced reception operation.

[0035] In the electronic watch disclosed herein, it is preferable that when the reception control unit is set to the reception permitted state and the automatic reception conditions are met, the reception control unit executes reception by the receiving unit, and when the reception control unit is set to the reception prohibited state and the automatic reception conditions are met, the receiving unit does not execute reception, and the memory unit stores a failure as the reception result. If the reception prohibition state continues for a long period spanning the automatic reception cycle, time adjustment by reception will not be performed, and so time accuracy may decrease due to oscillation variations in the crystal oscillator, which may cause the displayed time to become inaccurate. For this reason, if the reception prohibition state is released after a time deviation has occurred, and the reception result display shows success, which is the reception result before the reception prohibition state, the user will determine that no time deviation has occurred because reception was successful, but in fact a time deviation has occurred and is outside the guaranteed range of time accuracy, resulting in a contradiction. In contrast, in the electronic watch disclosed herein, if the automatic reception conditions are met when reception is prohibited, the reception result is deemed to be a failure, and therefore when the reception prohibition state is released, the reception result display shows a failure, thereby preventing inconsistencies.

[0036] The control method for an electronic watch disclosed herein is a control method for an electronic watch that has a receiving unit that receives radio waves, a hand, an operating unit, and a memory unit that stores the reception result of whether reception by the receiving unit is successful or unsuccessful, and is characterized in that when a first operation of the operating unit is executed, if the receiving unit is set to a reception permitted state that allows reception by the receiving unit and the reception result stored in the memory unit is successful, the hand indicates a first position, if the receiving unit is set to the reception permitted state and the reception result stored in the memory unit is unsuccessful, the hand indicates a second position, and if the receiving unit is set to a reception prohibited state that prohibits reception by the receiving unit, the hand indicates a third position, and when a second operation of the operating unit is executed, the receiving permitted state and the reception prohibited state are switched between. According to the electronic timepiece control method of the present invention, the hand that displays the reception result and the hand that displays the reception prohibited state are the same, and when the first operation of the operation unit is performed, either the reception result or the reception prohibited state is displayed by the hand, so when the reception prohibited state is set, the reception result is not displayed. This prevents the user of the electronic timepiece from misunderstanding that the reception process is being performed when the reception prohibited state is set. Furthermore, by performing the second operation, the user of the electronic timepiece can set the reception permitted state or reception prohibited state as desired, improving convenience.
