Description

  The present invention relates to a composite display type timing device including an analog display unit and a digital display unit, and a composite display type timing device used as a time counter such as a clock for displaying time and a stopwatch for measuring and displaying time. About.

There is known an electronic timepiece (combination timepiece) including an analog display unit using a pointer or the like and a digital display unit using a liquid crystal panel or the like (see, for example, Patent Document 1).
The timepiece of Patent Document 1 is provided with a liquid crystal device on the surface of the watch, and the rotation shafts of the hour hand, the minute hand, and the second hand are inserted through the liquid crystal device.
And in the timepiece of Patent Document 1, the time is displayed with hour, minute, and second hands, and the time, calendar, alarm, timer, and the like are switched and displayed on the digital display unit.

JP 2002-116269 A

  However, in the timepiece of Patent Document 1, the current time can be displayed on the digital display unit, but three hands of the hour hand, the minute hand, and the second hand are provided so that the current time can be visually recognized only by the analog display unit. For this reason, the digital display unit and the hands are arranged so as to overlap each other in the thickness direction of the timepiece, and accordingly, the thickness of the timepiece increases, and it is difficult to make the timepiece thinner.

  An object of the present invention is to provide a composite display type timing device that includes an analog display unit and a digital display unit and can be made thin.

  A composite display type timing device according to the present invention is a composite display type timing device that includes an analog display unit having a pointer and a digital display unit having a display device, and displays the time or time by hour, minute, hour, minute, and second. The time is displayed on a digital display unit, and the minutes or minutes and seconds are displayed on an analog display unit.

Here, the analog display unit means a display unit that includes a pointer that is mechanically operated by a driving unit such as a stepping motor and that indicates information using the pointer. Moreover, a digital display part means the display part comprised with the display apparatus which can display a number at least. As this display device, for example, various display devices such as a liquid crystal display, an organic EL display, and an EPD (Electrophoretic Display) can be used.
The time means a time indicated by a normal clock such as the current time in a region set by the user. On the other hand, the time means a time measured by a time counter such as a stopwatch.

According to the present invention, in the time measuring device that displays the time and time only by the hour and minute and does not display the second, or the time measuring device that displays the time and time by the hour, minute, second, “hour” is displayed on the digital display unit. Since the display is changed at intervals shorter than “hour”, “minute” (in the case of hour / minute display) or “minute / second” (in the case of hour / minute / second display) is displayed on the analog display. The number of pointers in the analog display unit can be reduced, and the composite display type timing device can be made thinner accordingly.
In addition, since “time” is displayed on the digital display unit, it is possible to easily perform time correction work and time difference correction work. That is, in a general analog timepiece, the hour hand and the minute hand operate in conjunction with each other via a train wheel. Therefore, when the hour hand is corrected, the minute hand must be rotated by a number corresponding to the correction time. For example, when correcting the time from 3:00 am to 9:00 am, it is necessary to rotate the minute hand six times and move the hour hand by six hours. Even when the time is corrected to move overseas, there is a time difference of ± 12 hours at the maximum. Therefore, the hour hand must be moved by rotating the minute hand by the time difference, which takes time. The operation is complicated.
On the other hand, in the present invention, “hour” is displayed on the digital display section, and therefore, the number (“hour”) displayed on the digital display section may be changed by a button operation or the like. Since it is not necessary to rotate, correction operation can be performed easily.
Further, when the minute hand is set to the current time, etc., it is sufficient to set the minute hand to any one of 0 to 59 minutes. For this reason, the minute hand can be easily corrected by operating the crown.

  Furthermore, by displaying “hour” on the digital display unit, the number of gears in the wheel train for driving the pointer can be reduced. That is, the pointer is driven using a motor and a reduction gear train. Here, the decelerating wheel train is generally composed of the fifth wheel, the second wheel, the hour wheel, and the hour wheel sequentially from the sixth wheel provided on the output shaft of the motor. A minute hand is attached to the second wheel and an hour hand is attached to the hour wheel. Therefore, even if the second hand and the minute hand are not provided, the respective gears must be prepared if the hour hand is present. However, if the hour hand is not provided, the minute wheel and the hour wheel can be eliminated. Therefore, the number of gears can be reduced when the hour hand is not provided compared to the case where the second hand and the minute hand are not provided, and accordingly, the time measuring device can be made thinner and smaller, and the cost can be reduced.

  A composite display type timing device of the present invention is a composite display type timing device that includes an analog display unit having a pointer and a digital display unit having a display device, and displays time or time in hours, minutes, and seconds. The minutes may be displayed on a digital display unit, and the seconds may be displayed on an analog display unit.

According to the present invention, in a timing device that displays time and time in “hours, minutes, seconds”, “hours / minutes” are displayed on the digital display unit, and the display is changed at intervals shorter than the “hours / minutes”. Since “second” is displayed on the analog display section, the number of hands in the analog display section can be reduced, and the composite display type timing device can be made thinner accordingly.
In addition, since “hour / minute” is displayed on the digital display portion, it is not necessary to rotate the hour hand / minute hand by the correction time as in the case of the above-described invention, Time and time difference can be easily corrected.
Further, by displaying “hour / minute” on the digital display unit, it is possible to further reduce the wheel train for driving the pointer. That is, when only the second hand is provided, the reduction gear train may be provided sequentially from the sixth car provided on the output shaft of the motor to the fifth car and the fourth car. The number of gears can be reduced, and accordingly, the time measuring device can be reduced in thickness and size, and the cost can be reduced.

Here, the analog display unit includes two hands of a minute hand and a second hand, and the rotation axis of each pointer is a length from the rotation axis of each pointer to the tip of each pointer on a plane orthogonal to the axial direction of the rotation axis. It is preferable that they are provided apart from each other by the dimension added.
According to such a configuration, since the rotation trajectories of the tips of the pointers do not overlap in a planar manner, the pointers can be prevented from colliding even if the height positions along the rotation axes of the pointers are the same. For this reason, it is not necessary to provide different height positions for the hands as in a general timepiece in which the hands are provided on the same axis, and can be provided at the same height position. The thickness dimension can be reduced, and even if two pointers are provided, the thickness can be reduced to the same thickness as a timing device provided with only one pointer, and the composite display type timing device can be made thin. .

  A composite display type timing device of the present invention is a composite display type timing device that includes an analog display unit having a pointer and a digital display unit having a display device, and displays time or time in hours, minutes, and seconds. One of the minutes and seconds is displayed on the digital display unit, and the other two are displayed on the analog display unit having two pointers. The rotation axes of the two pointers are orthogonal to the axial direction of the rotation axis. In the plane, the distance from the rotation axis of each pointer to the tip of each pointer is provided at a distance or more.

  According to such a configuration, since the rotation trajectories of the tips of the pointers do not overlap in a planar manner, the pointers can be prevented from colliding even if the height positions along the rotation axes of the pointers are the same. For this reason, it is not necessary to provide different height positions for the hands as in a general timepiece in which the hands are provided on the same axis, and can be provided at the same height position. The thickness dimension can be reduced, and even if two pointers are provided, the thickness can be reduced to the same thickness as a timing device provided with only one pointer, and the composite display type timing device can be made thin. .

Here, the digital display unit is preferably configured using a memory-type display element.
The memory-type display element is an element capable of continuing display for a predetermined time without continuing power supply. For example, an electrophoretic display device such as an EPD (Electrophoretic Display) called so-called electronic paper can be used.

The use of a memory-type display element in the digital display can greatly reduce the power consumption for maintaining the display, and in particular, it can extend the battery life and extend the operable time in a portable timing device such as a wristwatch. , Battery replacement and charging can be reduced, and convenience can be improved.
In addition, since the memory-type display element consumes power when the display is updated, the power consumption can be reduced by increasing the display update interval. Accordingly, when the second display is displayed on the analog display unit and “minute” for updating the display at intervals of 1 minute is displayed on the digital display unit, “second” for updating the display at intervals of 1 second is displayed on the digital display unit. Power consumption can be reduced compared to the case of displaying. Furthermore, if “seconds / minutes” are displayed on the analog display unit and “hours” for updating the display at intervals of one hour are displayed on the digital display unit, the power consumption can be further reduced.

Here, it is preferable that the digital display unit also serves as a dial.
The analog display unit usually includes a dial plate on which a scale of a pointer is displayed. However, when the dial plate is stacked on the surface of the digital display unit, the thickness dimension of the time measuring device is increased accordingly. On the other hand, if the digital display portion is also used as a dial as in the present invention, the time measuring device can be made thinner by the thickness dimension of the dial. Furthermore, if a dot matrix type digital display unit is used, the display of the digital display unit can be freely controlled, so the design of the digital display unit that is also used as a dial can be freely changed, and the design of the timing device can be improved. It can be improved.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[First Embodiment]
[Composition of combination clock]
FIG. 1 is a front view of a combination timepiece 1 which is a composite display type timing device according to the present invention.
The combination timepiece 1 includes a timepiece main body 10 and a band 15 and is a wristwatch type that a user wears on his arm.

As shown in FIG. 2, the watch body 10 includes an exterior case (trunk) 11 formed in a substantially rectangular tube shape, a cover glass (windshield) 12 mounted on the surface side of the exterior case 11, and an exterior case 11. And a back cover 13 that is detachably attached to the back side.
The exterior case 11 is not limited to a substantially rectangular tube shape (planar rectangular shape), but may be a substantially cylindrical shape (planar circular shape or elliptical shape). It is not limited to things.

  A pair of band attaching portions 11A is formed at both ends of the outer case 11, and a spring bar is detachably provided between the band attaching portions 11A. The band 15 is attached between the band attaching portions 11A using a spring bar.

  In the outer case 11, a display panel (display device) 20, a pointer 30, and a movement 40 are provided. In the present embodiment, the movement 40 is disposed in the outer case 11 via the middle frame 14, and even when the shape and size of the outer case 11 are changed, the middle frame 14 according to the shape and size. By using the movement 40, the same movement 40 can be used.

The display panel 20 is configured by an electrophoretic display device such as an EPD (Electrophoretic Display) called electronic paper manufactured in a shape and size corresponding to the outer case 11. As the display panel 20, other memory display devices, for example, display devices having various memory properties such as an electrochromic display (ECD), a ferroelectric liquid crystal, and a cholesteric liquid crystal can be used.
The display panel 20 constitutes a digital display unit in the present invention. In the present embodiment, since a separate dial is not provided on the display panel 20, the display panel 20 is also used as a dial.

  The pointer 30 is disposed in a space between the cover glass 12 and the display panel 20 and is provided so as to be visible from the cover glass 12. In the present embodiment, the minute hand 31 and the second hand 32 are provided as the pointer 30, and the hour hand is not provided. The rotation axes of the minute hand 31 and the second hand 32 are provided from the movement 40 so as to penetrate the display panel 20 and protrude into the space.

The movement 40 is configured to control the driving of the hands 30 (the minute hand 31 and the second hand 32) and also to drive the display panel 20.
That is, as shown in FIG. 3, the movement 40 includes a control circuit 41 composed of an IC or the like, a drive means 42 for driving the hands 30, an oscillation circuit 43, a power supply means 44, and an external input device 45. It is configured with.

  The driving means 42 includes a stepping motor 46 for driving the pointer, and a train wheel 47 for transmitting the output of the motor 46 to the minute hand 31 and the second hand 32. As shown in FIG. 4, the wheel train 47 is a deceleration that sequentially decelerates from the sixth wheel 471 provided on the output shaft of the motor 46 to the fifth wheel 472, the fourth wheel 473, the third wheel 474, and the second wheel 475. It is a train wheel. The second hand 32 is attached to the fourth wheel 473 and the minute hand 31 is attached to the second wheel 475.

The oscillation circuit 43 is configured by a crystal resonator or the like and outputs a pulse signal having a predetermined frequency.
The power supply means 44 is composed of a primary battery or a secondary battery. When a rechargeable secondary battery is provided, a solar cell that can charge the secondary battery and a power generation means using a rotating weight are also provided.

The external input device 45 is composed of a crown and buttons for performing various settings and operations, and recognizes an operation by the user and outputs an operation signal to the control circuit 41.
In the present embodiment, the external input device 45 includes a crown 451 and buttons 452 and 453 as shown in FIG. That is, the crown 451 and the buttons 452 and 453 are disposed on the side surface of the watch body 10 as shown in FIG. Note that the position and number of the crowns 451 and the buttons 452 and 453 are not limited to those shown in FIG. 1 and may be provided at positions that can be operated by the user depending on the shape of the watch body 10 and the like. That's fine.

The control circuit 41 includes a pulse synthesis circuit 411, a drive control circuit unit 412, an analog display unit drive circuit 413, and a digital display unit drive circuit 414.
The pulse synthesis circuit 411 divides the pulse signal output from the oscillation circuit 43 and outputs a predetermined reference signal (usually a 1 Hz pulse signal) to the drive control circuit unit 412.

The drive control circuit unit 412 includes a time counter 415. The time counter 415 stores calendar information such as date and time, and time information such as hour, minute, second, and the like. These values can be corrected by the external input device 45 and the reference from the pulse synthesizing circuit 411. It is configured to be sequentially updated by a signal. For example, the time counter 415 includes an hour counter, a minute counter, a second counter, a day counter, a month counter, and a year counter. When a 1 Hz reference signal is input from the pulse synthesis circuit 411, the drive control circuit unit 412 updates the second counter. When the second counter reaches 60 seconds, the minute counter is advanced by 1 minute, and the minute counter is 60 minutes. Then, the hour counter is advanced by 1 hour, so that the current time can be stored and updated.
Further, the drive control circuit unit 412 updates the day counter by one day when the hour counter reaches 24 hours, and updates the month counter by one month when the day counter is updated from the last day of the month, so that the current year is updated. The month and date can also be updated.

The drive control circuit unit 412 outputs drive control signals CS1 and CS2 to the analog display unit drive circuit 413 and the digital display unit drive circuit 414 based on the information of the time counter 415, respectively.
The drive control signal CS1 output to the analog display unit drive circuit 413 is a pulse signal output at 1 second intervals in response to the update of the second information of the time counter 415.
On the other hand, the drive control signal CS2 output to the digital display unit drive circuit 414 is time information displayed on the display panel 20, and in the present embodiment, is a signal indicating a number indicating “hour”.

When the drive control signal CS <b> 1 is input from the drive control circuit unit 412, the analog display unit drive circuit 413 outputs a drive pulse to the stepping motor 46. That is, the analog display unit driving circuit 413 drives the stepping motor 46 by the driving pulse to step the second hand 32 every second. The minute hand 31 is moved in conjunction with the driving of the stepping motor 46.
On the other hand, since the hour of the hour, minute, and second is displayed on the display panel 20 that is a digital display portion, the digital display portion drive circuit 414 receives the “1” of the drive control signal CS2 input from the drive control circuit portion 412. When the “hour” is changed, the display panel 20 is controlled to update the display. Accordingly, the digital display unit driving circuit 414 updates the display of “hour” on the display panel 20 at intervals of one hour.

  Therefore, in the combination timepiece 1 of the present embodiment, “minute / second” is displayed by the analog display unit having the hands 31 and 32, and “hour” is displayed by the digital display unit having the display panel 20. In addition, since “hour” is displayed in a large size using almost the entire surface of the display panel 20, even if the hands 31 and 32 are moving on the display panel 20, the portion hidden by the hands 31 and 32 is a number. It is only a part of. For this reason, even if the hands 31 and 32 are arranged on the display panel 20, the discrimination of “hour” displayed on the display panel 20 is not lowered.

According to this embodiment, the following effects can be obtained.
(1) Since “hour” is displayed on the display panel 20 which is a digital display section and “minute / second” is displayed by the hands 30 (minute hand 31 and second hand 32) which are analog display sections, a normal analog clock is displayed. Compared to, hour hand can be eliminated. For this reason, it is not necessary to place the hour hand on the minute hand 31 and the second hand 32 so that the timepiece 1 can be thinned. Further, it is possible to eliminate the need for gears (the minute wheel and hour wheel) for driving the hour hand, the number of gears can be reduced, and the timepiece 1 can be reduced in thickness and size accordingly.
Further, since only “hour” is digitally displayed, “hour” can be easily visually recognized as compared with a normal digital clock that digitally displays all “hour, minute, and second”. In addition, since “minute / second” is indicated by the pointer 30 of the analog display unit, it can be intuitively grasped.
That is, the combination timepiece 1 of the present embodiment digitally displays “hour” and analogly displays “minute / second”, so that the timepiece can be easily reduced in thickness and size and the time can be easily set. A watch that can be grasped and is easy to use.

(2) Since “time” is digitally displayed, time correction and time difference correction processing can be easily performed as compared with a normal analog clock.
That is, when adjusting the time with a normal analog timepiece, it is necessary to stop the hand movement and operate the crown to rotate the hour hand and the minute hand. For this reason, every time the hour hand moves for one hour, it is necessary to rotate the minute hand once, which takes time for the correction work.
On the other hand, in the present embodiment, “hour” is digitally displayed. Therefore, it is only necessary to change a numerical value displayed digitally by pressing a predetermined button, and the time correction operation can be easily performed. Note that even when the time difference is corrected, it can be easily corrected in the same manner because it may be corrected in time units.

(3) Since the display panel 20 which is a digital display unit is configured by a display panel having memory properties such as EPD, power consumption can be reduced and battery life can be extended. In particular, in this embodiment, since “hour” is displayed on the display panel 20, the display is rewritten only every hour, and the frequency of rewriting can be reduced. The display panel 20 having a memory property such as EPD consumes power when rewriting, and does not consume power when the display is maintained. Displaying 20 can significantly reduce power consumption compared to digital display of “minutes” and “seconds”.

(4) Since the display panel 20 also serves as a dial, the timepiece 1 can be made thinner than when the dial is stacked on the display panel 20. Furthermore, if the dial is formed by the display panel 20, the dial of various designs can be freely set by controlling the display of the display panel 20, so that the design of the combination timepiece 1 can be further improved.

[Second Embodiment]
Next, a second embodiment of the present invention will be described. Note that, in each embodiment described below, the same or similar components as those in the above-described embodiments are denoted by the same reference numerals, and description thereof is omitted or simplified.
As shown in FIG. 5, the combination timepiece 1B according to the second embodiment is different from the combination timepiece 1 according to the first embodiment only in that only the minute hand 31 is provided as an analog display unit and no second hand is provided. Other configurations are the same. That is, the combination clock 1B is a clock that displays only “hour / minute” and does not display a second.
Even if the second hand is not provided, the train wheel from the motor 46 to the second wheel 475 for driving the minute hand 31 is the same as that in the first embodiment.

Also in this embodiment, the same operational effects as those of the first embodiment can be obtained.
In particular, since the hand 30 is only the minute hand 31, the combination timepiece 1B can be made thinner than the combination timepiece 1 of the first embodiment in which the minute hand 31 and the second hand 32 are arranged so as to overlap in the rotation axis direction.

[Third Embodiment]
Next, a third embodiment of the present invention will be described.
As shown in FIG. 6, the combination timepiece 1C according to the third embodiment is provided with only the second hand 32 as an analog display unit, and the display panel 20 which is a digital display unit has an hour (“23” in FIG. 6) and minute ( In FIG. 6, “10”) is displayed.
Since the train wheel 47 only needs to drive the second hand 32, there is no need to provide the third wheel 474 and the second wheel 475.

Also in this embodiment, the same operational effects as those of the first embodiment can be obtained.
In particular, since the hand 30 is only the second hand 32, the timepiece 1C can be made thinner than the combination timepiece 1 of the first embodiment. That is, the combination clock 1C of the present embodiment displays “hour / minute” on the display panel 20 and indicates “second” with the second hand 32, so that the combination clock 1B can display only “hour / minute”. The timepiece can be reduced to the same thickness dimension and can display up to the second.

[Fourth Embodiment]
Next, a fourth embodiment of the present invention will be described.
As shown in FIG. 7, the combination timepiece 1D of the fourth embodiment is provided with only the minute hand 31 and the second hand 32 as an analog display unit, and the time is displayed on the display panel 20 which is a digital display unit. As shown in FIG. 8, the minute hand 31 and the second hand 32 are provided with rotating shafts 31 </ b> A and 32 </ b> A at different positions on the timepiece surface, unlike the timepieces 1 to 1 </ b> C.

Specifically, the rotary shafts 31A and 32A of the minute hand 31 and the second hand 32 are separated from the rotary shafts 31A and 32A of the pointers 31 and 32 on a plane orthogonal to the axial direction of the rotary shafts 31A and 32A, that is, the surface of the display panel 20. The pointers 31 and 32 are provided apart from each other by at least the length obtained by adding the lengths up to the tips.
For this reason, even if the hands 31 and 32 are provided at the same height position in the thickness direction of the combination timepiece 1D, the hands 31 and 32 are configured not to collide with each other when the hands 31 and 32 rotate. .

Also in this embodiment, the same operational effects as those of the first embodiment can be obtained.
In addition, by separating the rotary shafts 31A and 32A of the minute hand 31 and the second hand 32 by a predetermined dimension, the hands 31 and 32 can be arranged at the same height position. Thus, as in the combination timepiece 1 of the first embodiment, Compared with the case where the hands 31 and 32 are stacked in the thickness direction of the timepiece, the thickness dimension of the timepiece 1D can be reduced.

[Fifth Embodiment]
Next, a fifth embodiment of the present invention will be described.
As shown in FIG. 9, a combination timepiece 1E according to the fifth embodiment includes a minute hand 31 and a second hand 32 as an analog display unit. The second hand 32 is a so-called small second hand, and is a pointer smaller than the second hand 32 of each of the embodiments.
The rotary shafts 31A and 32A of the minute hand 31 and the second hand 32 are provided at different positions. However, the interval between the rotary shafts 31A and 32A is larger than the length dimension from the rotary shaft 32A of the second hand 32 to the tip of the second hand 32, and the length dimension from the rotary shaft 31A of the minute hand 31 to the tip of the minute hand 31. Is set to a smaller dimension. For this reason, the height position of the minute hand 31 is on the cover glass 12 side with respect to the second hand 32, and is configured so as not to interfere with the second hand 32 when the minute hand 31 rotates.

  Note that at least “hour” is displayed on the display panel 20, and the minute hand 31 and the second hand 32 are provided so as to be able to display the current time of the hour, minute, and second. Further, in the present embodiment, as shown in FIG. 9, “hour / minute” is digitally displayed in the lower area of the display panel 20 by controlling the digital display unit driving circuit 414 by performing a predetermined button operation or the like. It is also configured to be able to.

Also in this embodiment, the same operational effects as those of the first embodiment can be obtained.
In addition, since the rotary shafts 31A and 32A of the minute hand 31 and the second hand 32 can be arranged close to each other, the surface area of the timepiece can be reduced compared to the combination timepiece 1D, and the timepiece can be further downsized.

[Sixth Embodiment]
Next, a sixth embodiment of the present invention will be described.
The combination watch 1F of the sixth embodiment displays one of the hour, minute, and second on the digital display unit, and the other two on the analog display unit having two hands, and rotates the two hands. It is a timepiece in which axes are provided at different positions.

  Specifically, as shown in FIG. 10, “second” is digitally displayed on the display panel 20, and the minute hand 31 and the hour hand 33 are arranged apart from each other. That is, the rotation shaft 31A of the minute hand 31 and the rotation shaft 33A of the hour hand 33 are arranged apart from each other by a dimension obtained by adding the lengths of the minute hand 31 and the hour hand 33 (length from the rotation shaft to the tip). Yes. Thereby, even if the minute hand 31 and the hour hand 33 are arranged at the same height position, they can move without interference.

Also in this embodiment, the same operational effects as those of the fourth embodiment can be obtained.
That is, since the hands 31 and 33 can be arranged at the same height position by separating the rotating shafts 31A and 33A of the minute hand 31 and the hour hand 33, the hands 31 and 33 are provided as in the combination timepiece 1 of the first embodiment. The thickness dimension of the timepiece 1F can be reduced as compared with the case where the timepieces are stacked in the thickness direction of the timepiece.
Since the display panel 20 displays “seconds”, the display is updated every second. For this reason, since there is no merit of using a display panel having memory characteristics such as EPD, a liquid crystal panel or the like may be used as the display panel 20.

[Modification of Embodiment]
It should be noted that the present invention is not limited to the above-described embodiments, and modifications, improvements, and the like within the scope that can achieve the object of the present invention are included in the present invention.
For example, in the combination timepiece 1 of the first embodiment, only the numeral indicating “hour” is displayed on the display panel 20, but as shown in FIG. 11, the numeral indicating “hour” (“12” in FIG. 11). ”) As well as the current time in another city. In FIG. 11, the time in Hong Kong, which is a time difference of -1 hour with respect to the time in Japan, is displayed.
Furthermore, the display mode for displaying only “hour” in FIG. 1 and the display mode for displaying the time of another city in FIG. 11 may be switched and displayed by a predetermined button operation.

  In each of the above embodiments, the display panel 20 also serves as a dial, but a dial may be provided in addition to the display panel 20. When dials are stacked on the surface side of the display panel 20, the dials are formed of a light-transmitting material (for example, glass or plastic) so that the display on the display panel 20 can be viewed from the watch surface. That's fine.

  The display panel 20 is not limited to a display element having a memory property such as EPD, and a display element such as a liquid crystal display or an organic EL display may be used.

  As a combination clock, when displaying hour / minute / second or hour / minute, one or two of them may be displayed on the digital display, and the other one or two may be displayed on the analog display. .
