Description

  The present invention relates to a wireless function watch including an antenna for receiving a predetermined radio wave and a conductive housing for housing the antenna.

  Conventionally, timepieces with wireless functions such as personal computer communication functions, mobile phone functions and contactless IC card functions are known. Among them, long wave standard radio waves (carrier waves) including time information are received and based on the time information. A radio timepiece having a wireless function for correcting the time is well known.

By the way, such a watch with a wireless function includes an antenna for receiving a predetermined radio wave, like other communication devices.
For this reason, in a wireless function watch, it is conceivable that a radio wave reception sensitivity is improved by forming a housing, which is a housing for housing an antenna, from a non-conductive material such as a synthetic resin.

However, these timepieces with a wireless function are timepieces, unlike other communication devices, and therefore require a beautiful appearance and a high-class feeling as an ornament or accessory.
For this reason, it is required to employ a conductive material, that is, a metal material, instead of a non-conductive material such as a synthetic resin for a housing which is a housing for housing the antenna.

  This is because a housing such as a synthetic resin gives the user an inexpensive appearance and a feeling of wearing due to its texture, color tone, or light weight, whereas a metal housing has a high-class feeling. This is to give the user a certain appearance and wearing feeling.

This demand for a metal housing is particularly significant in a wristwatch as an accessory carried by a user.
However, when the antenna is housed in a conductive housing, i.e., a metal housing, the magnetic flux generated in the vicinity of the antenna is absorbed by the metal housing, which is a conductive material, and the resonance phenomenon is hindered. The reception function for the antenna to receive standard radio waves will be significantly reduced.

For this reason, various proposals for improving reception sensitivity have been made.
For example, Patent Document 1 discloses a radio timepiece including a metal housing that is a metal casing, particularly a radio timepiece.

That is, as shown in FIG. 21, the radio timepiece 100 includes a housing 102.
In the present specification, the “vertical direction” means the vertical direction in FIG. 21 or FIG. Therefore, the upper surface is a surface exposed outward when the wristwatch is worn on the wrist, and the lower surface is a surface facing the wrist in the same state.

  The “planar direction” is a direction orthogonal to the vertical direction and means the horizontal direction in FIG. 21. The planar direction may overlap the longitudinal direction of the band or the width direction of the band.

The housing 102 includes a watch case 104 constituting a metal frame, a metal back cover 106 which is mounted in a sealed state so as to cover a lower surface opening of the watch case 104, and an upper surface opening of the watch case. And a windshield (glass) 108 mounted in a sealed state.

  In the housing 102, a movement 110 constituting a timepiece driving unit and a solar cell 112 disposed on the upper surface of the movement 110 for driving the movement by an electromotive force of light are provided. On the upper surface of the solar cell 112, there is provided a dial plate 114 having a translucent function that transmits external light having a wavelength contributing to power generation by the solar cell 112 at least enough to drive the movement 110.

Further, an antenna 116 for receiving standard radio waves is attached below the side of the movement 110.
Although not shown, a minute hand and an hour hand are arranged on a needle shaft that protrudes from the movement 110 and penetrates the solar cell 112 and the dial plate 114. These minute hand and hour hand are positioned between the dial plate 114 and the windshield 108 to display the time.

  Further, the watch case 104 includes two sets of band attaching portions 118 projecting outward, and the band attaching portions 118 are disposed at a predetermined interval so as to face each other. The leg part 120 extended from 104 is provided.

A wristwatch band (not shown) is connected between each of the leg portions 120.
By the way, in the radio timepiece 100 adopting such a metal exterior, when the antenna 116 receives radio waves, the eddy current along the circumferential direction of the annular wall is induced in the metal timepiece case 104. Will flow as.

This eddy current cancels out radio waves from the outside of the housing 102, and the reception sensitivity of the antenna 116 is extremely lowered.
In order to avoid such a phenomenon, in the radio timepiece 100 of Patent Document 1, the annular wall of the timepiece case 104 is provided with a slit 122 that divides the timepiece case 104 in the circumferential direction.

  That is, as shown in FIG. 21, the watch case 104 is completely divided in the vertical direction by the slit 122. As a result, the watch case 104 has a substantially C-shaped frame shape by the slit 122. It has become.

  In FIG. 21, the slit 122 is omitted for clarity and is not shown, but the slit 122 is embedded with an insulating member made of non-conductive synthetic resin. ing.

That is, the insulating member is configured to maintain the waterproofness and strength of the watch case 104.
Therefore, in the radio timepiece 100 having the slit 122, since the eddy current does not flow along the circumferential direction of the annular wall of the timepiece case 104 when the antenna 116 receives a radio wave, a conductive metal timepiece case. Even when 104 is adopted, reception of the antenna 116 is ensured.
JP 2002-341057 A

However, in the radio timepiece 100 of Patent Document 1, since a slit 122 is formed in a part of the watch case 104 and an insulating member made of a synthetic resin is embedded in the slit 122, the appearance is not good. Compared to a watch case made entirely of metal, it is not as high-quality and the strength of the insulating member is inevitably weakened, resulting in waterproofness, impact resistance, wear resistance, and chemical resistance. Will also be inferior.

  In view of such a current situation, the present invention provides a watch with a wireless function that has a good appearance, has a high-class feeling, is excellent in strength, and can reliably receive radio waves by an antenna housed inside. The purpose is to do.

The present invention was invented in order to achieve the problems and objects in the prior art as described above,
The wireless function watch of the present invention is
A housing;
An antenna housed in the housing for receiving radio waves from the outside;
A conductive rotating bezel rotatably disposed on the housing;
At least one slit for dividing the rotating bezel in the circumferential direction;
It is characterized by providing.

Thus, since the slit which divides the rotation bezel in the circumferential direction is formed in the conductive rotation bezel which is rotatably arranged on the housing, eddy current flows along the rotation bezel by this slit. Will be cut off and generation of eddy current will be prevented.

As a result, a decrease in the reception sensitivity of the antenna due to the eddy current flowing in the rotating bezel is prevented, and the reception sensitivity of the antenna is improved.
Further, since the rotating bezel is disposed on the housing, it is separate from the housing, and even if a slit is formed in the rotating bezel, the waterproof property of the housing itself does not deteriorate.

  The housing including the watch case in the present invention may be conductive such as metal or non-conductive such as synthetic resin. Alternatively, conductive parts and non-conductive parts may be mixed in the parts constituting the housing.

  A housing is understood to be a member that is at least partially conductive or at least partially non-conductive. Regardless of conductivity or non-conductivity, if a slit is provided in the conductive rotating bezel disposed on the housing, a decrease in antenna reception sensitivity due to the eddy current of the rotating bezel can be avoided.

  In the present invention, the conductive member refers to “a material whose member is a conductive member” or “a member coated with a conductive film”. In the latter case, the material of the member itself may be a non-conductive material, a conductive material, or a combination of a non-conductive material and a conductive material.

On the other hand, the non-conductive member means “a member whose material itself is a non-conductive member” or “a member whose non-conductive film is coated”. In the latter case, the material of the member itself may be a non-conductive material, a conductive material, or a combination of a non-conductive material and a conductive material.

As the conductive material constituting the rotating bezel, gold, silver, copper, brass, aluminum, magnesium, zinc, titanium, or an alloy thereof is employed. Further, for example, a titanium alloy, stainless steel, tantalum carbide, or the like may be employed.

In addition, the wireless function watch of the present invention is
An insulating member is disposed in the slit of the rotating bezel.
In this way, the conductive rotating bezel disposed on the watch case is formed with a slit that divides the rotating bezel in the circumferential direction, and the insulating member is disposed in the slit. Thus, the flow of eddy currents along the line is interrupted, and the generation of eddy currents is prevented.

As a result, a decrease in the reception sensitivity of the antenna due to the eddy current flowing in the rotating bezel is prevented, and the reception sensitivity of the antenna is improved.
The insulating member may be a member made of a non-conductive material or a member in which a non-conductive film is coated on a conductive material. As the non-conductive material, synthetic resin, rubber, ceramic, or the like is employed. As the conductive material, the above-described rotating bezel material is employed.

  As the non-conductive film that is coated on the conductive material, that is, the insulating film, an insulating film of an organic material such as an acrylic material, a urethane material, or a cellulose material is employed. In addition, as this insulating film, for example, a chromium compound-based film containing a chromium compound or an aluminum oxide-based film containing an aluminum oxide compound is employed.

  As the chromium compound-based coating, a chromium oxide-based coating including a chromium oxide compound, a chromium nitride-based coating including a chromium nitride compound, and a chromium carbide-based coating including a chromium carbide compound are employed.

  Further, as the insulating film, an insulating film serving as an insulating region disposed between a rotating bezel and a watch case described later, such as DLC (Diamond Like Carbon), may be employed.

Further, instead of the insulating coating, an insulating sheet made of synthetic resin or rubber may be attached.
The insulating member is preferably fixed to the rotating bezel so as not to be pulled out carelessly. As this fixing means, mechanical engagement means such as fitting, press-fitting, joining, insert molding, etc. are employed. As a bonding layer for bonding the insulating member and the rotating bezel, an adhesive, a pressure-sensitive adhesive, a double-sided tape, or the like is used. These bonding layers are preferably non-conductive insulating layers.

In addition, the wireless function watch of the present invention is
The insulating member is a non-conductive synthetic resin.
By configuring the insulating member from a non-conductive synthetic resin in this way, the rotating bezel can be reliably insulated at the slit portion, and the insulating member that matches the size and shape of the slit, for example, is integrally molded. Etc. can be easily manufactured.

In addition, the wireless function watch of the present invention is
The color tone of the viewing surface of the insulating member is the same color tone as the color tone of the viewing surface of the rotating bezel.

  Thus, by configuring the color tone of the viewing surface of the insulating member to be the same color tone as that of the viewing surface of the rotating bezel, the insulating member becomes difficult to be visually recognized, and the appearance of the rotating bezel and the appearance of the watch itself are improved. It will be.

In addition, “same color tone” means that the color tone of the rotating bezel and the insulating member are within the range where both can be recognized as the same color tone, and the appearance of the color tone, such as shades of light and shade, is completely It is not limited to matching. For example, a deep gold color, a light gold color, a light gold color, or a dark gold color are all assumed to be the same color tone of gold here.

  For example, even if the rotating bezel has a light gold color tone and the insulating member has a dark gold color tone, if the viewing surface of the rotating bezel and the insulating member has the same color tone of gold, the insulating member becomes difficult to be visually recognized. The beauty of the watch and the watch itself are improved.

  Further, when the color tone of the viewing surface of the insulating member is the same color tone as the color tone of the viewing surface of the rotating bezel, the color tone of the viewing surface of the rotating bezel and the insulating member is the color tone of the material of the rotating bezel and the insulating member itself. Even the color tone of the coating film coated on the rotating bezel and the insulating member may be used.

Examples of such a film include a paint film, a printed film, and a dry plating film.
The outer surface of the rotating bezel and the insulating member other than the viewing surface may have the same color tone, and all the outer surfaces of the rotating bezel and the insulating member may have the same color tone.

In this state, the locking claw 51 of the click spring member 47 is fixed to an engaging portion (not shown) provided on the bottom surface of the annular groove 43.

  Further, a click groove 41 that is a continuous unevenness is formed below the rotating bezel 36. When such a rotating bezel 36 is attached to the annular groove 43 on which the click spring member 47 is mounted, the click spring 41 is provided. The elastic claw 49 of the member 47 and the click groove 41 of the rotating bezel 36 are elastically engaged.

  As a result, when the user rotates the rotating bezel 36, the click spring member 47 and the rotating bezel 36 are mechanically engaged with each other so that a click feeling of the rotating bezel 36 is felt.

  Such a click mechanism including the rotation bezel 36 and the click spring member 47 functions as positioning means for preventing the rotation bezel 36 from being inadvertently rotated and stopping the rotation bezel 36 at an appropriate angular position.

  The support frame 54 is preferably made of a nonconductive material such as a synthetic resin. Such a support frame 54 secures a gap in the plane direction between the conductive watch case 14 and the antenna 26 when the watch case 14 constituting a part of the housing is made of a conductive material such as stainless steel. The reception performance of the antenna 26 is kept high.

Further, as the conductive material constituting the rotating bezel 36, gold, silver, copper, brass, aluminum, magnesium, zinc, titanium, or an alloy thereof can be employed.

Moreover, titanium alloy, stainless steel, tantalum carbide, etc. can also be employed.
By the way, in such a wireless function watch 10, when the antenna 26 receives radio waves, an eddy current along the circumferential direction flows through the conductive rotating bezel 36 as an induced current.

This eddy current cancels out the radio waves from the outside of the housing 12, and the reception sensitivity of the antenna 26 is extremely lowered.
In order to avoid such a phenomenon, in the wireless function watch 10 of the present invention, a slit 56 for dividing the rotating bezel 36 in the circumferential direction is formed.

By providing the slit 56 in this way, the flow of eddy current along the annular rotating bezel 36 is divided, and the generation of eddy current is prevented.
As a result, a decrease in the reception sensitivity of the antenna 26 due to the eddy current flowing in the rotating bezel 36 is prevented, and the reception sensitivity of the antenna 26 is improved.

That is, the insulating member 78 has substantially the same cross section as that of the rotary bezel 36 and can be mounted in the slit 56.
With this configuration, a slit 56 that divides the rotating bezel 36 in the circumferential direction is formed in the conductive rotating bezel 36 disposed on the watch case 14, and an insulating member 78 is disposed in the slit 56. Therefore, the insulating member 78 divides the flow of eddy currents along the rotating bezel 36 and prevents the generation of eddy currents.

As a result, a decrease in the reception sensitivity of the antenna 26 due to the eddy current flowing in the rotating bezel 36 is prevented, and the reception sensitivity of the antenna 26 is improved.
Further, since the insulating member 78 is arranged in the slit 56 in this way, the strength of the rotating bezel 36 is also maintained.

  Further, since the cross section of the insulating member 78 has substantially the same shape as the cross section of the rotating bezel 36, the viewing surface of the insulating member 78 forms substantially the same plane as the viewing surface of the rotating bezel 36. .

The insulating members 78 may be provided in the same number as the slits 56 provided in the rotating bezel 36. When the slits 56 are provided in one place, one insulating member 78 is provided, and the slits 56 are provided in a plurality of places. In such a case, the same number of insulating members 78 as the number of slits 56 may be provided.

Further, the insulating material constituting the insulating member 78 is not particularly limited, but a non-conductive insulating material such as synthetic resin, rubber, or ceramic can be employed.
It is also possible to use a member in which a non-conductive film is coated on a conductive material.

The insulating member 78 can be replaced with a non-conductive bonding layer for bonding the rotating bezel 36 and the additional member 80. As the bonding layer, a non-conductive adhesive layer or a non-conductive adhesive layer, for example, an adhesive layer or an adhesive layer containing a non-conductive material such as a synthetic resin may be employed. As the non-conductive adhesive layer, for example, a double-sided adhesive tape is employed.

FIG. 16 is a wireless function watch according to the seventh embodiment of the present invention, and is a perspective view for explaining a state in which an insulating member and an additional member are mounted in the slit, and FIG. 17 is a seventh embodiment of the present invention. It is a timepiece with a radio function in an example, and is a perspective view explaining a state where an insulating member and an additional member are mounted in a slit.

  The wireless function watch 10 of this embodiment has basically the same configuration as the wireless function watch 10 shown in FIGS. 1 to 3, and the same reference numerals are given to the same components. Detailed description thereof will be omitted.

  In the wireless function watch 10 of this embodiment, as shown in FIG. 16 or FIG. 17, the additional member 80 includes a cover portion 80 c that covers at least a part of the boundary between the rotating bezel 36 and the insulating member 78. .

By configuring in this way, the boundary between the rotating bezel 36 and the insulating member 78 is hidden by the covering portion 80c of the additional member 80 and is not visually recognized, so that the aesthetic appearance and luxury of the rotating bezel 36 are further improved.

  Further, in this case, in order to attach the additional member 80 to the insulating member 78, an engaging convex portion 80d is formed on the back surface of the additional member 80, and an engaging hole 78d is formed in the insulating member 78 correspondingly. Thus, the additional member 80 is attached to the insulating member 78 by the engagement between the engagement convex portion 80d and the engagement hole portion 78d.

With this configuration, the additional member 80 can be more securely fixed to the insulating member 78 by the engagement between the engagement convex portion 80d and the engagement hole portion 78d.
In this case, the additional member 80 is connected to the insulating member 78 by engaging the engaging convex portion protruding from one of the insulating member 78 and the additional member 80 with the engaging hole formed at the other. It is possible to provide the additional member with an engagement hole in the additional member, and it is also possible to provide an engagement protrusion in the insulating member 78.

Furthermore, it is desirable to form an extending portion 78 e extending from the insulating member 78 between the cover portion 80 c of the additional member 80 and the rotating bezel 36.
With this configuration, the covering portion 80c of the conductive additional member 80 extending beyond the boundary between the rotating bezel 36 and the insulating member 78 is blocked by the extending portion 78e of the insulating member 78, and the conductive portion 80c is electrically conductive. There will be no contact with the rotating bezel 36.

  As a result, since the conductive additional member 80 and the rotating bezel 36 are reliably insulated, an eddy current is prevented from being generated in the rotating bezel 36 and the receiving sensitivity of the antenna 26 is improved.

  In this case, in this embodiment, the extension part 78e extending from the insulating member 78 is set shorter than the cover part 80c of the additional member 80, but the extension part 78e is substantially the same as the cover part 80c. As a result, the covering portion 80c of the conductive additional member 80 is completely blocked by the extending portion 78e of the insulating member 78 and does not come into contact with the conductive rotating bezel 36, and eddy current is generated in the rotating bezel 36. This is avoided and the reception sensitivity of the antenna 26 is improved.

In addition, as in the fourth embodiment, a decorative member 84 made of a gemstone such as a gemstone or a precious stone that causes a viewer to have a beauty is formed on such an additional member 80, so that the beauty and luxury of the rotating bezel 36 can be obtained. This will further improve the aesthetics of the watch itself.

FIG. 18 is a wireless function watch according to the eighth embodiment of the present invention, and is a perspective view illustrating a state in which a reinforcing member is fixed to a recess provided on a rotating bezel. FIG. FIG. 20 is a perspective view for explaining a state in which a reinforcing member is fixed to a concave portion provided on a rotating bezel, which is a wireless function watch in the eighth embodiment, and FIG. 20 is a wireless view in the eighth embodiment of the present invention. It is a functional timepiece, and is a partial cross-sectional view illustrating a state in which a reinforcing member is fixed to a recess provided on a rotating bezel.

  The wireless function watch 10 of this embodiment has basically the same configuration as the wireless function watch 10 shown in FIGS. 1 to 3, and the same reference numerals are given to the same components. Detailed description thereof will be omitted.

In the wireless function watch 10 of this embodiment, as shown in FIGS. 18 to 20, a step portion 57 is formed inside the upper end of the rotating bezel 36, and the reinforcing member 53 is fixed to the step portion 57. It is like that. As the fixing means, mechanical engagement means such as fitting, press-fitting, joining, insert molding, and screwing are employed. Further, when the reinforcing member 53 and the rotating bezel 36 are joined, an adhesive, an adhesive, a double-sided tape, or the like is used for the joining layer. When the reinforcing member 53 is made of a conductive material such as metal, it can be fixed by brazing, welding, laser welding, or the like.

If such a reinforcing member 53 has an annular shape as in the present embodiment, the rotating bezel 36 can be reinforced over the entire circumferential direction of the step portion 57 provided on the rotating bezel 36.
Note that the reinforcing member 53 only needs to be disposed across the slit 56 of the rotating bezel 36, thereby making the slit 56 of the rotating bezel 36 difficult to be seen so that the beauty of the wristwatch is not impaired.

The insulating material constituting the reinforcing member 53 is not particularly limited, but a non-conductive insulating material such as synthetic resin, rubber, or ceramic can be employed.
It is also possible to use a member in which a non-conductive film is coated on a conductive material.

  In this case, as the conductive material constituting the reinforcing member 53, gold, silver, copper, brass, aluminum, magnesium, zinc, titanium, or an alloy thereof is used in the same manner as the conductive material constituting the rotating bezel 36. Etc. can be adopted. Moreover, titanium alloy, stainless steel, tantalum carbide, etc. can also be employed.

  And as a nonelectroconductive film coat | covered with the electroconductive material which comprises this reinforcement member 53, ie, an insulating film, a nonelectroconductive coating film, a nonelectroconductive printing film, and a nonelectroconductive dry-type plating film are included. Can be mentioned.

Moreover, as such an insulating film,
-CVD film such as DLC ( Diamond Like Carbon),
・ Insulating coatings of organic materials such as acrylic materials, urethane materials, or cellulose materials,
・ Chromium compound coatings containing chromium compounds or aluminum oxide coatings containing aluminum oxide compounds,
Etc. can be adopted.

  As the chromium compound-based coating, a chromium oxide-based coating containing a chromium oxide compound, a chromium nitride-based coating including a chromium nitride compound, or a chromium carbide-based coating including a chromium carbide compound can be employed.

Further, instead of such an insulating coating, an insulating sheet made of synthetic resin, rubber, or the like may be the reinforcing member 53 adhered to the conductive material constituting the reinforcing member 53.
Furthermore, the color tone of the viewing surface of the reinforcing member 53 can be the same color tone as the color tone of the viewing surface of the rotating bezel 36.

  Thus, if the color tone of the viewing surface of the reinforcing member 53 is configured to be the same color tone as the color tone of the viewing surface of the rotating bezel 36, the reinforcing member 53 becomes difficult to be visually recognized, and the beauty of the rotating bezel 36, the watch itself Aesthetics will be improved. The “viewing surface” refers to a region of the outer surface that is visually recognized by an observer.

Further, the color tone of the viewing surface of the reinforcing member 53 can be a color tone and a different color tone of the viewing surface of the rotating bezel 36.
By doing in this way, the part of the reinforcing member 53 can be easily visually recognized by an observer such as a watch wearer as aesthetics or as some information.

In this case, the “same color tone” means that the color tone of the rotating bezel 36 and the reinforcing member 53 are both within the range where they can be recognized as the same color tone. It is not limited to the perfect match of the texture.

  Note that the color tone of the viewing surface of the rotating bezel 36 and the reinforcing member 53 is the color tone of the coating film coated on the rotating bezel 36 and the reinforcing member 53 even if the color tone of the material of the rotating bezel 36 and the reinforcing member 53 itself. May be.

Accordingly, the “different color tone” refers to a combination of color tones where the color tone of the viewing surface of the rotating bezel 36 and the reinforcing member 53 is not recognized as the same color tone.
Furthermore, an index indicating the function display of the timepiece can be formed on the reinforcing member 53.

  In this way, the reinforcing member 53 has a time display, date display, day display, month display, year display, battery remaining amount display, display of external environment measurement values such as pressure and temperature, antenna reception sensitivity display, and antenna reception. By forming an index indicating the function display of the watch such as a success / failure display of the watch, the function display of the watch can be shown to an observer such as a watch wearer.

In particular, when an index is formed on the reinforcing member 53 having a color tone and a different color tone on the viewing surface of the rotating bezel 36, the function display of such a watch can be easily seen by an observer.
As described above, since the insulating region 59 is provided between the rotating bezel 36 and the reinforcing member 53, no induced current is generated between the rotating bezel 36 and the reinforcing member 53. Decrease in receiving sensitivity of the antenna 26 due to eddy current flowing between the antenna 26 and the antenna 53 is prevented, and the receiving sensitivity of the antenna 26 is improved.

In this case, the insulating region 59 can be composed of an insulating member disposed between the rotating bezel 36 and the reinforcing member 53.
As an insulating member constituting such an insulating region 59, a non-conductive insulating member such as synthetic resin, rubber, or ceramic can be employed.

  It is also possible to use a member in which a nonconductive film is coated on a conductive material. In this case, as the conductive material constituting the insulating member, gold, silver, copper, brass, aluminum, magnesium, zinc, titanium, or an alloy thereof can be employed. Moreover, titanium alloy, stainless steel, tantalum carbide, etc. can also be employed.

  And as a nonelectroconductive film coat | covered with the electroconductive material which comprises this insulating member, ie, an insulating film, a nonelectroconductive coating film, a nonelectroconductive printing film, a nonelectroconductive dry-type plating film is mentioned. It is done.

Moreover, as such an insulating film,
-CVD film such as DLC ( Diamond Like Carbon),
-Insulating coatings of organic materials such as acrylic materials, urethane materials, or cellulose materials,
・ Chromium compound coatings containing chromium compounds or aluminum oxide coatings containing aluminum oxide compounds,
Etc. can be adopted.

  As the chromium compound-based coating, for example, a chromium oxide-based coating containing a chromium oxide compound, a chromium nitride-based coating including a chromium nitride compound, or a chromium carbide-based coating including a chromium carbide compound can be employed.

Further, instead of such an insulating coating, an insulating member made of a synthetic resin or rubber may be attached to a conductive material constituting the insulating member.
In this case, the insulating member can be attached to the rotating bezel 36 side.

  With this configuration, for example, since a sheet-like insulating member only needs to be attached to the rotating bezel 36 side, it becomes easy to incorporate the reinforcing member 53 on the rotating bezel 36, improving work efficiency, and manufacturing cost. Can be reduced.

In addition, the insulating member can be attached to the reinforcing member 53 side.
With this configuration, for example, a sheet-like insulating member only needs to be attached to the lower surface of the reinforcing member 53. Therefore, the reinforcing member 53 can be easily incorporated into the stepped portion 57 of the rotating bezel 36, and work efficiency is improved. In addition, the manufacturing cost can be reduced.

Further, the insulating region 59 can also be constituted by an insulating film formed on at least one of the rotating bezel 36 and the reinforcing member 53.
Thus, by forming the insulating film by painting, vapor deposition, or the like, an insulating region 59 made of the insulating film can be formed on at least one of the boundary surfaces between the rotating bezel 36 and the reinforcing member 53, Work efficiency can be improved and manufacturing costs can be reduced.

When an insulating film is formed on the rotating bezel 36, it can be formed on the entire surface of the rotating bezel 36.
As a method of forming an insulating film on the entire surface of the rotating bezel 36, the insulating film can be formed by immersing the rotating bezel 36 in an insulating material liquid. If this method is used, work efficiency can be improved and manufacturing cost can be reduced.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to this. For example, the watch case 14 and the back cover 16 constituting the housing 12 are made of conductive metal. A conductive part and a non-conductive part may be mixed.

  The housing 12 may be a member that is at least partly conductive or at least partly non-conductive, and various modifications can be made without departing from the object of the present invention.
