DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, the embodiments of the present invention will be described with reference to the drawings. However, the embodiments described below are subject to various limitations that are technically preferable for implementing the present invention. Therefore, the technical scope of the present invention is not limited to the following embodiments and illustrated examples.

[0010] [Electronic Clock 1 Configuration] First, the configuration of the electronic timepiece 1 of this embodiment will be described. Fig. 1 is a block diagram showing the general functional configuration of an electronic timepiece 1. Fig. 2 is a diagram showing the external appearance of the electronic timepiece 1. As shown in Fig. 2, the electronic timepiece 1 is, for example, a wristwatch-type timepiece.

[0011] 1, the electronic watch 1 includes a CPU (Central Processing Unit) 41, a ROM (Read Only Memory) 42, a RAM (Random Access Memory) 43, an oscillator circuit 44, a frequency divider circuit 45, and a timing circuit 46. The electronic watch 1 further includes an operation unit 50, motors 31-35, wheel train mechanisms 21-25, a second hand 11, a minute hand 12, an hour hand 13, a pointer 14, a pointer 15, a sensor 61, a battery remaining amount detection unit 62, a digital display unit 73, and a battery 80.

[0012] The CPU 41 loads programs from the ROM 42 into the RAM 43 and executes them to control the operation of the electronic clock 1, provide a time display function and other functions, and switch between these functions. For example, the CPU 41 executes a mode shift process (see FIG. 4) described later in cooperation with a program read from the ROM 42, thereby realizing the function of a control unit.

[0013] The ROM 42 is a non-volatile memory that stores programs for controlling the operation of the electronic clock 1, such as the time display function, and various data. The RAM 43 is a volatile or non-volatile memory, and temporarily stores the programs stored in the ROM 42 and temporarily stores data necessary for controlling the operation of the electronic timepiece 1.

[0014] The oscillator circuit 44 uses, for example, a crystal oscillator to generate a signal of a predetermined frequency and outputs it to the frequency divider circuit 45 . The frequency divider circuit 45 divides the frequency signal and outputs the result to the clock circuit 46 and the CPU 41. The clock circuit 46 counts the signal input from the frequency divider circuit 45 and adds it to an initial value to calculate the current date and time, and outputs the calculation result to the CPU 41.

[0015] 2, and receives a pressing operation from a user and outputs a signal corresponding to the pressing operation to the CPU 41. The operation unit 50 also includes a crown .

[0016] The motors 31 to 35 rotate according to instructions from the CPU 41. Motor 31 rotates second hand 11 via train wheel mechanism 21, which is an arrangement of multiple gears. Motor 32 rotates minute hand 12 via train wheel mechanism 22. Motor 33 rotates hour hand 13 via train wheel mechanism 23. Second hand 11, minute hand 12, and hour hand 13 correspond to the second pointer of the present invention.

[0017] The motor 34 rotates the hand 14 via the train wheel mechanism 24. The hand 14 corresponds to a first hand of the present invention. The motor 35 rotates the hand 15 via the train wheel mechanism 25. It is preferable that second hand 11, minute hand 12, hour hand 13, pointer 14, and pointer 15 are coated with phosphorescent paint.

[0018] The sensor 61 is an air pressure sensor that measures air pressure and outputs the measurement result to the CPU 41. In an atmospheric pressure mode, which is an operation mode for measuring and displaying atmospheric pressure, the CPU 41 causes the sensor 61 to measure atmospheric pressure at predetermined time intervals (e.g., every two minutes). The CPU 41 also causes the sensor 61 to automatically measure atmospheric pressure at predetermined time intervals (e.g., every two hours) and store the measurement results in an atmospheric pressure storage area (not shown) of the RAM 43. A predetermined number of (e.g., 10) measurement results from automatic measurement are stored in the atmospheric pressure storage area in a FIFO (First in First out) order. In this embodiment, the sensor 61 is an air pressure sensor. However, the sensor 61 may include other sensors such as a direction sensor, a temperature sensor, and a humidity sensor.

[0019] The battery remaining capacity detection unit 62 detects the remaining capacity of the battery 80 and outputs the detection result to the CPU 41 . The battery 80 supplies power to each component of the electronic timepiece 1. The battery 80 is, for example, a secondary battery that is charged by a solar cell (not shown) built in under the translucent dial 70.

[0020] The digital display unit 73 is configured with a display screen such as a liquid crystal display or an organic EL (Electro Luminescence) display, and performs various displays according to instructions from the CPU 41.

[0021] A dial 70 is provided within the housing 2 of the electronic timepiece 1, the top of which is covered by a transparent crystal not shown. In this embodiment, the dial 70 is circular as shown in Fig. 2, with hour characters 71 (indexes) and scales arranged along the circumferential direction of the dial 70. The second hand 11, minute hand 12, and hour hand 13, as well as an axis O1 for rotating these, are provided at the center of the dial 70. The second hand 11, minute hand 12, and hour hand 13 (second pointer) rotate around the axis O1 to appropriately point to the hour characters 71 or scales to display the time.

[0022] In addition, an atmospheric pressure display unit 72 (first display unit) etc. is provided on a part of the dial 70, and a digital display unit 73 (second display unit) is provided (fitted) in a part of the dial 70 in an area different from the atmospheric pressure display unit 72.

[0023] FIG. 3 is an enlarged view of the atmospheric pressure display section 72 enclosed by the dashed line in FIG. As shown in FIG. 3, the atmospheric pressure display section 72 is provided with a pointer 14, a base position 72a, an atmospheric pressure pointer area 72b (second area), and a battery remaining amount pointer area 72c (first area).

[0024] The atmospheric pressure indicator area 72b is an area where the hand 14 indicates the atmospheric pressure (second information) in the atmospheric pressure mode. The atmospheric pressure indicator area 72b is provided with a plurality of scales 721, numbers 722 corresponding to the scales 721, and a code display area 723. The scale 721 is a scale (second scale) for the needle 14 to indicate the atmospheric pressure. The atmospheric pressure display unit 72 of this embodiment indicates the difference in atmospheric pressure from the reference, which is the atmospheric pressure automatically measured immediately before, and has 13 scales 721 indicating +2, +4, +6, +8, +10, OVER (+10 or more), -2, -4, -6, -8, -10, and UNDER (-10 or less), with the scale 721 indicating 0 at the center (reference scale). The numbers 722 correspond to the scale marks 721. The numbers 722 include characters such as "OVER" and "UNDER" as shown in FIG. The sign display area 723 is an area that indicates whether the number 722 is positive or negative.

[0025] The interval of the scale 721 can be arbitrarily set by the user through the operation of the operation unit 50, a smartphone, etc. For example, the interval of the scale 721 may be set to 2 (hPa) so that the scale 721 changes by 1 every time the pressure difference changes by 2 (hPa), or the interval of the scale 721 may be set to 100 (hPa) so that the scale 721 changes by 1 every time the pressure difference changes by 100 (hPa).

[0026] The battery remaining amount indicator area 72c is an area having a scale (first scale) for indicating the remaining battery amount (level of remaining battery amount, corresponding to first information) of the hand 14. The battery remaining amount indicator area 72c has a scale (H scale 724) representing H (High), a scale (M scale 725) representing M (Middle), and a scale (L scale 726) representing L (Low) as the first scale. The scale 721 of the atmospheric pressure indicator area 72b is located outside (away from the center of the dial 70) the scales (H scale 724, M scale 725, L scale 726) of the battery remaining amount indicator area 72c on the dial 70. This makes it possible to prevent the visibility of the air pressure difference, which is displayed for a longer period of time, from being reduced by the hour hand 13, etc.

[0027] The hand 14 normally points to the base position 72a. When transitioning to the atmospheric pressure mode, the hand 14 rotates around the axis O2 (rotation axis) to point to one of the scales 721 depending on the current atmospheric pressure, thereby indicating the atmospheric pressure. When returning to the BT (Base Time) mode, which is the basic clock mode (time display mode), the hand 14 also rotates around the axis O2 (rotation axis) to point to one of the H scale 724, M scale 725, or L scale 726 depending on the remaining charge of the battery 80, thereby indicating the remaining battery charge.

[0028] The digital display unit 73 performs various displays in response to the transition of the operation mode of the electronic timepiece 1. Details will be described later.

[0029] [Electronic clock 1 display operation] Next, the display operation of the electronic timepiece 1 will be described. The electronic watch 1 has one or more operation modes that provide functions other than the current time display, in addition to the BT mode (first mode) that displays the current time. In this embodiment, the electronic watch 1 has an air pressure mode that measures and displays the air pressure, and a stopwatch mode that provides a stopwatch function, but it may have other operation modes, such as a compass mode, a world time mode, a thermometer mode, etc. Even in an operation mode other than the BT mode, the second hand 11, the minute hand 12, and the hour hand 13 are controlled to display the current time.

[0030] In the electronic watch 1, the BT mode is the basic operating mode, but the user can transition (switch) the operating mode every time he presses the S3 button 53 as a mode shift key. In this embodiment, every time the S3 button 53 is pressed from the BT mode, the operating mode is switched in the following order: BT mode → atmospheric pressure mode → stopwatch mode → BT mode ...

[0031] As described above, in the electronic watch 1 of this embodiment, the remaining battery level is displayed for a predetermined time on the air pressure display unit 72 at the timing of returning (switching) from another mode to the BT mode. However, the pointer 14 that displays the remaining battery level is located below the second hand 11, minute hand 12, and hour hand 13 that display the time in the viewing direction. Therefore, if the second hand 11, minute hand 12, or hour hand 13 overlaps with the pointer 14, the user cannot see the remaining battery level display (see FIG. 8(a)). Similarly, when the remaining battery level is displayed only on the digital display unit 73, if the second hand 11, minute hand 12, or hour hand 13 overlaps with the remaining battery level display, the user cannot see the remaining battery level display. Furthermore, when the remaining battery level is displayed only on the digital display unit 73, there is no problem with visibility in a bright space, but it is difficult to see in a dark space, and if the pointer 14 is coated with phosphorescent paint, the display of the pointer 14 is easier to see if it does not overlap with other hands. Therefore, in the electronic watch 1, the CPU 41 executes the mode shift process shown in Figure 4, and when returning from another operating mode to the BT mode, the remaining battery level is displayed on both the atmospheric pressure display unit 72 and the digital display unit 73, thereby improving the visibility of the remaining battery level in the electronic watch 1. In this embodiment, when switching to an operation mode other than the BT mode, the air pressure display unit 72 does not display the remaining battery level. It is considered that the user switches to an operation mode other than the BT mode when he or she wishes to use a function provided in that operation mode, and as described above, the remaining battery level display requires the pointer 14 to be moved, which takes time before the function becomes available. On the other hand, the timing to return to the BT mode is when the user has finished using the function in the other operation mode, so the remaining battery level can be displayed at a timing that does not disturb the user.

[0032] 4 is a flowchart showing the flow of the mode shift process executed by the CPU 41. The mode shift process is executed by the CPU 41 in cooperation with a program stored in the ROM 42 in response to operation of the S3 button 53 serving as a mode shift button while the electronic watch 1 is in operation.

[0033] First, the CPU 41 performs display in the BT mode. Specifically, the CPU 41 controls the motors 31 to 33 based on the current time (date and time) output from the clock circuit 46 to rotate the second hand 11, minute hand 12, and hour hand 13 to display the current time. The CPU 41 also displays the current time or date on the digital display unit 73 based on the current time (date and time) output from the clock circuit 46. The CPU 41 also rotates the hands 14 of the atmospheric pressure display unit 72 to the basic position 72a by the motor 34 (step T1). The current time indication by the second hand 11, minute hand 12, and hour hand 13 continues while the electronic clock 1 is in operation.

[0034] FIG. 5(a) is a diagram showing an example of the display of the electronic timepiece 1 in the BT mode. As shown in FIG. 5(a), in the BT mode, the digital display unit 73 displays the current time or date. The hand 14 of the atmospheric pressure display unit 72 is set to the basic position 72a. FIG. 5(a) shows an example in which the day of the week (SU (Sunday)) and the date (12.30) are displayed on the digital display unit 73. Note that, as the display of the digital display unit 73 in the BT mode, it is possible to display the current time as shown in FIG. 5(b) or an atmospheric pressure tendency graph and date as shown in FIG. 5(c) depending on the user's settings. The "p" displayed on the digital display unit 73 in FIG. 5(b) indicates PM (afternoon). The atmospheric pressure tendency graph is a graph showing the measurement results of the sensor 61 that are automatically measured and stored in the above-mentioned atmospheric pressure storage area.

[0035] Next, the CPU 41 determines whether or not the S3 button 53, which is a mode shift button, has been pressed (step T2). When it is determined that the S3 button 53 has not been pressed (step T2; NO), the CPU 41 returns to step T1 and repeats steps T1 to T2.

[0036] If it is determined that the S3 button 53 has been pressed (step T2; YES), the CPU 41 transitions to the atmospheric pressure mode, causes the digital display unit 73 to display the mode name (BARO) for a predetermined period of time (e.g., one second), and controls the motor 34 to rotate the pointer 14 to the position on the scale 721 corresponding to the number 722 "0" in the atmospheric pressure pointer area 72b, and displays the pointer 14 at the position on the scale 721 corresponding to "0" for the predetermined period of time (step T3).

[0037] FIG. 6(a) is a diagram showing an example of the display of the electronic timepiece 1 at a predetermined time immediately after switching to the atmospheric pressure mode. As shown in Fig. 6(a), immediately after the mode is switched to the atmospheric pressure mode, the mode name (BARO) indicating the atmospheric pressure mode is displayed for a predetermined period of time on the digital display unit 73. This allows the user to recognize that the mode has been switched to the atmospheric pressure mode. Also, on the atmospheric pressure display unit 72, the pointer 14 is displayed for a predetermined period of time at the position on the scale 721 corresponding to the "0" of the number 722.

[0038] Next, the CPU 41 obtains the measurement result of the sensor 61, and causes the atmospheric pressure display unit 72 and the digital display unit 73 to display the atmospheric pressure (step T4). In step T4, the CPU 41 acquires the measurement result of the sensor 61, and calculates the air pressure difference between the acquired measurement result and a reference value. The reference value here is the air pressure value acquired by the most recent automatic measurement. The CPU 41 then controls the motor 34 based on the calculated air pressure difference, rotates the pointer 14 to the position on the scale 721 that corresponds to the number 722 according to the calculated air pressure difference, and displays the air pressure difference. The CPU 41 also causes the digital display unit 73 to display the measurement result (current air pressure value) and an air pressure trend graph.

[0039] FIG. 6(b) is a diagram showing an example of the display of the electronic timepiece 1 showing the result of atmospheric pressure measurement in the atmospheric pressure mode. As shown in Fig. 6(b), in the atmospheric pressure mode, the measurement result (hPa) of the sensor 61 is displayed on the right side of the digital display 73. Fig. 6(b) shows that the current atmospheric pressure value is 1013 (hPa). In addition, an atmospheric pressure trend graph is displayed on the left side of the digital display 73. In addition, in the atmospheric pressure display 72, the needle 14 indicates the position of the scale 721 corresponding to the number 722 according to the atmospheric pressure difference, thereby displaying the atmospheric pressure difference.

[0040] Next, the CPU 41 judges whether or not the S3 button 53 has been pressed (step TT5). When it is determined that the S3 button 53 has not been pressed (step T5; NO), the CPU 41 returns to step T4 and repeats steps T4 to T5.

[0041] If it is determined that the S3 button 53 has been pressed (step T5; YES), the CPU 41 transitions to the stopwatch mode, causes the digital display unit 73 to display the mode name (STW) for a predetermined period of time (e.g., one second), and controls the motor 34 to rotate the pointer 14 to the basic position 72a (step T6).

[0042] FIG. 7(a) is a diagram showing an example of the display of the electronic timepiece 1 at a predetermined time immediately after transition to the stopwatch mode. As shown in Fig. 7(a), immediately after the mode is switched to the stopwatch mode, the mode name (STW) indicating the stopwatch mode is displayed for a predetermined time on the digital display 73. This allows the user to recognize that the mode has been switched to the stopwatch mode. Also, on the atmospheric pressure display 72, the hand 14 is displayed at the basic position 72a for a predetermined time.

[0043] Next, the CPU 41 causes the digital display unit 73 to display a time measurement screen (step T4). FIG. 7(b) is a diagram showing an example of the display of the electronic timepiece 1 in the stopwatch mode. As shown in Fig. 7(b), in the stopwatch mode, a time measurement screen is displayed on the digital display unit 73. Fig. 7(b) shows a state in which the measured time has been reset. In the stopwatch mode, for example, when the S1 button 51 is pressed, the CPU 41 starts time measurement and counts up the measured time on the time measurement screen. When the S1 button 51 is pressed again, the CPU 41 ends the time measurement and displays the measurement result on the time measurement screen.

[0044] Next, the CPU 41 judges whether or not the S3 button 53 has been pressed (step TT8). When it is determined that the S3 button 53 has not been pressed (step T8; NO), the CPU 41 returns to step T7 and repeats steps T7 to T8.

[0045] If it is determined that the S3 button 53 has been pressed (step T8; YES), the CPU 41 obtains the remaining charge (%) of the battery 80 from the battery remaining charge detection unit 62, and determines whether the remaining battery charge (level) is Low (step T9). Here, for example, when 0 ≤ battery remaining amount < n1, the CPU 41 determines that the battery remaining amount is Low; when n1 ≤ battery remaining amount < n2, the CPU 41 determines that the battery remaining amount is Middle; and when n2 ≤ battery remaining amount, the CPU 41 determines that the battery remaining amount is High. Note that n1 to n3 are positive numbers, and 0 ≤ n1 < n2 ≤ 100.

[0046] When it is determined that the battery remaining amount is not Low (step T9; NO), that is, when it is determined that the battery remaining amount is High or Middle, the CPU 41 returns to the BT mode, causes the digital display unit 73 to display the mode name (TIME) indicating that it is in the BT mode and the battery remaining amount display for a predetermined time (for example, 1 second), controls the motor 34 to rotate the pointer 14 to the position of the H scale 724 or the M scale 725, and displays the pointer 14 at the position of the H scale 724 or the M scale 725 for a predetermined time (for example, 1 second) (step T10), and then returns to step T1. In the embodiment, when the pointer 14 indicates the H scale 724, the M scale 725, or the L scale 726, it is assumed that the pointer 14 indicates the central portion of the range of each scale. However, the position indicated by the pointer 14 may be changed according to the magnitude of the battery remaining amount. Here, in step T10, for example, when the predetermined time for displaying the battery remaining amount is 1 second, the pointer 14 moves as follows: "basic position 72a → display the H scale 724 or the M scale 725 for 1 second → basic position 72a". Therefore, when the pointer 14 indicates the H scale 724, there is a slight overlap in the battery remaining amount display between the barometric pressure display unit 72 and the digital display unit 73. However, when the pointer 14 indicates the M scale 725, there is no overlap in the battery remaining amount display between the barometric pressure display unit 72 and the digital display unit 73, and the pointer 14 reaches the M scale 725 after the display of the digital display unit 73 changes to the display in the BT mode.

[0047] FIG. 8(a) is a diagram showing an example of the display of the electronic clock 1 at a predetermined time immediately after returning to the BT mode when the battery remaining amount is High. As shown in FIG. 8(a), immediately after returning to the BT mode, the mode name (TIME) indicating the BT mode is displayed for a predetermined time on the right side of the digital display unit 73. This allows the user to recognize that the mode has been returned to the BT mode. Furthermore, on the left side of the digital display unit 73, the letter "H" indicating that the remaining battery level is High is displayed in a color inverted from the mode name "TIME". In other words, the letter indicating the remaining battery level is highlighted in a different display mode from the letters indicating other information. Furthermore, in the atmospheric pressure display unit 72, the pointer 14 is moved so as to point to the H scale 724 in the battery remaining level pointer area 72c, and the fact that the remaining battery level is High is displayed for a predetermined time.

[0048] FIG. 8(b) is a diagram showing an example of the display of the electronic timepiece 1 at a predetermined time immediately after returning to the BT mode when the remaining battery charge is at a middle level. As shown in FIG. 8(b), immediately after returning to the BT mode, the mode name (TIME) indicating the BT mode is displayed for a predetermined time on the right side of the digital display unit 73. This allows the user to recognize that the mode has been returned to the BT mode. Furthermore, on the left side of the digital display unit 73, the letter "M" indicating that the remaining battery level is Middle is displayed in a color inverted from the mode name "TIME". That is, the letter indicating the remaining battery level is highlighted in a display mode different from that of the letters indicating other information. Furthermore, in the atmospheric pressure display unit 72, the pointer 14 is moved so as to point to the M scale 725 of the battery level pointer area 72c, and the fact that the remaining battery level is Middle is displayed for a predetermined time.

[0049] As shown in FIG. 8(a) and FIG. 8(b), when returning to the BT mode, the battery remaining level is displayed for a predetermined time on both the atmospheric pressure display unit 72 and the digital display unit 73, so that the visibility of the battery remaining level, which is only displayed temporarily, can be improved, and the user can be prevented from overlooking the battery remaining level. For example, if the second hand 11, the minute hand 12, or the hour hand 13 overlaps with the pointer 14 of the atmospheric pressure display unit 72, the user cannot visually determine which scale in the battery remaining level pointer area 72c the pointer 14 is pointing to, but since the battery remaining level is displayed on the digital display unit 73, the user can visually determine the battery remaining level. Also, if the second hand 11, the minute hand 12, or the hour hand 13 overlaps with the battery remaining level display of the digital display unit 73, the battery remaining level display becomes invisible, but since the battery remaining level is displayed on the atmospheric pressure display unit 72, the user can visually determine the battery remaining level. Also, even if the surroundings are dark and the digital display unit 73 is difficult to see, the user can visually determine the battery remaining level through the atmospheric pressure display unit 72.

[0050] On the other hand, if it is determined in step T9 that the remaining battery power is low (step T9; YES), the CPU 41 returns to the BT mode and causes the digital display unit 73 to display the mode name (TIME) indicating that it is in the BT mode and the remaining battery power for a predetermined period of time (e.g., one second), and controls the motor 34 to rotate the pointer 14 to the position of the L scale 726 and display the pointer 14 at the position of the L scale 726 for the predetermined period of time (step T11).

[0051] FIG. 9(a) is a diagram showing an example of the display of the electronic timepiece 1 at a predetermined time immediately after returning to the BT mode when the remaining battery level is Low. As shown in FIG. 9(a), immediately after returning to the BT mode, the mode name (TIME) indicating the BT mode is displayed for a predetermined period of time on the right side of the digital display unit 73. This allows the user to recognize that the mode has been returned to the BT mode. Furthermore, on the left side of the digital display unit 73, the letter "L" indicating that the remaining battery level is Low is displayed in a color inverted from the mode name "TIME". In other words, the letter indicating the remaining battery level is highlighted in a different display mode from the letters indicating other information. Furthermore, in the atmospheric pressure display unit 72, the pointer 14 is moved so as to point to the L scale 726 in the remaining battery level pointer area 72c, and the fact that the remaining battery level is Low is displayed for a predetermined period of time.

[0052] When the display in step T11 ends, CPU 41 causes digital display section 73 to flash the letter "L" as a display to warn of a low battery level (step T12). 9(b), the CPU 41 blinks the character "L" (including the background) displayed on the digital display unit 73. The pointer 14 of the atmospheric pressure display unit 72 remains pointing to the L scale 726.

[0053] Here, the battery level judged as Low is a very low battery level, and if left as is, it will soon become impossible to display the time. Therefore, when the battery level is judged to be Low, the CPU 41 blinks the letter "L" (including the background) on the digital display 73 as a warning of a low battery level. The system does not return to BT mode and continues to issue the warning until the user charges the battery 80 and the battery level returns to Middle or higher.

[0054] Next, the CPU 41 obtains the remaining capacity (%) of the battery 80 from the battery remaining capacity detection unit 62, and determines whether the remaining battery capacity is equal to or greater than Middle (step T13). When it is determined that the remaining battery level is not equal to or higher than Middle (step T13; NO), the CPU 41 returns to step T12. When it is determined that the remaining battery charge is equal to or greater than Middle (step T13; YES), the CPU 41 returns to step T1. During operation of the electronic timepiece 1, the CPU 41 repeatedly executes the processes of steps T1 to T13.

[0055] The display of steps T3, T6, and T10 can be cancelled and the display can be moved to the next step by pressing the S2 button 52. However, since it takes time for the pointer 14 to rotate, if the S2 button 52 is pressed before the pointer 14 points to the correct scale corresponding to the battery remaining amount in the battery remaining amount pointer area 72c in step T10 to return to the BT mode, the user may mistakenly recognize the battery remaining amount if the pointer 14 is immediately returned to the basic position 72a. Therefore, if the battery remaining amount display is cancelled before the pointer 14 points to the scale corresponding to the battery remaining amount, the CPU 41 rotates the pointer 14 to the scale corresponding to the battery remaining amount and then returns it to the basic position 72a. This prevents the user from mistakenly recognizing the battery remaining amount.

[0056] Furthermore, since the remaining battery level is only displayed for a predetermined time (for example, 1 second), the electronic watch 1 may incorporate an LED (Light Emitting Diode) that illuminates the dial 70 so that the user does not miss it. The CPU 41 may automatically turn on the LED when displaying the remaining battery level (i.e., when returning to the BT mode). Alternatively, the CPU 41 may determine the brightness around the electronic watch 1 when displaying the remaining battery level (i.e., when returning to the BT mode), and turn on the LED if the brightness is equal to or lower than a predetermined threshold. The brightness may be determined using a solar cell, or a sensor that detects brightness may be incorporated and the determination may be made using the detection result of the brightness sensor. This makes it possible to ensure that the user does not miss the remaining battery level display even when in a dark place. In addition, the function of automatically turning on the LED when displaying the remaining battery level may be switched on / off by pressing the SA button 55.

[0057] In addition, in the electronic watch 1, when it is desired to return to the BT mode from an operation mode other than the BT mode, the S3 button 53 can be pressed and held for a predetermined period of time or longer to return to the BT mode. In other words, it is also possible to return (switch) directly from the atmospheric pressure mode to the BT mode without passing through the stopwatch mode. Here, the hand 14 can rotate forward (clockwise) and backward (counterclockwise), and the forward rotation moves three times faster than the reverse rotation. Therefore, when switching from the atmospheric pressure mode to the BT mode, the CPU 41 specifies the rotation direction in which the hand 14 will reach the scale position corresponding to the remaining battery level in the battery remaining amount hand area 72c from its current position (the scale position that the hand 14 should point to) sooner, and rotates the hand 14 in the specified rotation direction by the motor 34. For example, when the hand 14 is rotated from "-8" on the scale 721 to the L scale 726 as the remaining battery charge, the hand 14 is rotated in the reverse direction because the hand reaches the L scale 726 (the center of the L scale 726) sooner in the reverse direction. This allows the hand 14 to display the remaining battery charge more quickly. In addition, the rotation speed in the reverse direction may be faster than that in the forward direction. In this case, not only when transitioning from the atmospheric pressure mode to the BT mode, but also when transitioning from the basic position 72a to the battery remaining amount pointer (for example, when transitioning from the stopwatch mode to the BT mode), the CPU 41 identifies the rotation direction in which the hand 14 will reach the scale position corresponding to the battery remaining amount in the battery remaining amount pointer area 72c from the current position (the scale position that the hand 14 should point to) sooner, and causes the motor 34 to rotate the hand 14 in the identified rotation direction.

[0058] As described above, the electronic watch 1 has the dial 70, the atmospheric pressure display unit 72 provided on a portion of the dial 70, and the digital display unit 73 provided on a portion of the dial 70 in an area different from the atmospheric pressure display unit 72. The CPU 41 causes both the digital display unit 73 and the atmospheric pressure display unit 72, which indicates the remaining battery level by means of a pointer 14, to display the remaining battery level for a predetermined period of time. This improves the visibility of the remaining battery power in the electronic timepiece 1.

[0059] For example, the hand 14 is positioned lower in the viewing direction than the second hand 11, minute hand 12, and hour hand 13, which display the time. Therefore, if the hand 14 overlaps with the second hand 11, minute hand 12, or hour hand 13, the user cannot see the remaining battery power when only the hand 14 of the atmospheric pressure display unit 72 is displayed, and the user may miss the remaining battery power. In the electronic watch 1, the remaining battery power is displayed for a predetermined period of time on both the digital display unit 73 and the atmospheric pressure display unit 72, improving the visibility of the remaining battery power.

[0060] Furthermore, when the remaining battery power is equal to or less than a predetermined threshold, the CPU 41 causes the digital display unit 73 to display a display warning the user that the remaining battery power is insufficient. This allows the user to recognize that the remaining battery power is insufficient.

[0061] The pointer 14 can rotate in a forward direction and a reverse direction, and when the CPU 41 displays the remaining battery level on the atmospheric pressure display unit 72, the pointer 14 rotates in a direction that allows the pointer 14 to reach the scale position of the remaining battery level from its current position quickly. For example, the atmospheric pressure display unit 72 has a battery level indicator area 72c in which a scale for indicating the remaining battery level is displayed by the pointer 14, and an atmospheric pressure indicator area 72b in which a scale 721 for indicating the atmospheric pressure difference, which is second information different from the remaining battery level, is displayed by the pointer 14, and the pointer 14 can be rotated in a forward direction or a reverse direction to switch between displaying the remaining battery level and the atmospheric pressure difference. When switching from a state in which the atmospheric pressure difference is indicated in the atmospheric pressure indicator area 72b to a state in which the battery level indicator area 72c indicates the remaining battery level, the CPU 41 rotates the pointer 14 in a direction that allows the pointer 14 to reach the scale position corresponding to the remaining battery level quickly. Therefore, the remaining battery level can be displayed quickly.

[0062] Furthermore, the atmospheric pressure indicator area 72b is provided on the outer side of the battery remaining amount indicator area 72c on the dial 70. This prevents the hour hand 13 and the like from reducing the visibility of the scale indicating the atmospheric pressure difference, which is displayed for a longer period of time.

[0063] Furthermore, when an instruction to cancel the remaining battery level display is given by pressing the S2 button 52 before the pointer 14 indicates the mark that should be indicated, the CPU 41 rotates the pointer 14 to the mark that indicates the remaining battery level that should be indicated, and then cancels the remaining battery level display. This prevents the user from misunderstanding the remaining battery level.

[0064] Furthermore, the CPU 41 displays the remaining battery level when the device returns to the BT mode, so that the remaining battery level can be displayed at a time that is not disruptive to the user.

[0065] Furthermore, when switching to an operation mode different from the BT mode, the CPU 41 does not display the remaining battery level on the air pressure display unit 72. This prevents the display of the remaining battery level from causing the functions provided in the operation mode to be switched to to be left unused for a long time.

[0066] Furthermore, when switching from an operation mode different from the BT mode to the BT mode, the CPU 41 displays for a predetermined time the mode name of the BT mode, which is the operation mode to be switched to, and the remaining battery level on the air pressure display unit 72. This eliminates the need to display the mode name display and the remaining battery level display separately (at different times).

[0067] Furthermore, the CPU 41 highlights the remaining battery level display in a display manner different from the mode name on the digital display unit 73. Therefore, by displaying the remaining battery level in an easily visible manner, it is possible to reduce the possibility that the user will overlook the remaining battery level display.

[0068] The description of the above embodiment is merely a suitable example of the electronic timepiece 1 according to the present invention, and is not intended to be limiting.

[0069] For example, in the above embodiment, an example was given of a case in which the remaining battery level is displayed on both the atmospheric pressure display unit 72 as the first display unit and the digital display unit 73 as the second display unit to improve the visibility of the remaining battery level, but the specified information (first information) displayed on both the first display unit and the second display unit is not limited to the remaining battery level.

[0070] In the above embodiment, the second information displayed on the atmospheric pressure display unit 72 as the first display unit, which is information other than the remaining battery level, is atmospheric pressure, but this is not limiting. For example, the second information may be other information such as altitude, temperature, humidity, world time, etc.

[0071] Furthermore, the order of transition of the operation modes and the types of operation modes described in the above embodiment are merely examples and are not limited to those described above.

[0072] In addition, the detailed configuration and operation of the electronic watch 1 may be modified as appropriate without departing from the spirit of the invention.

[0073] Although the embodiment of the present invention has been described above, the technical scope of the present invention is not limited to the above embodiment, but is defined based on the claims. Furthermore, the technical scope of the present invention also includes equivalent ranges that are made by adding modifications that are not related to the essence of the present invention from the claims.
