[0003] [Patent Document 1] JP 2005-323735 A Summary of the Invention [Problem to be solved by the invention]

[0004] In such a watch, in order to fit and secure a decorative member made of a brittle material in the mounting recess of the watch case, it is necessary to provide multiple retaining claws to hold the decorative member in the mounting recess. That is, in order to provide multiple retaining claws in the mounting recess of the watch case, it is necessary to form in the watch case a central groove passing through approximately the center of the mounting recess, a pair of side grooves extending parallel to each other on either side of this central groove, and a transverse groove extending in a direction perpendicular to the central groove and the side grooves.

[0005] As a result, in order to provide multiple retaining claws in the mounting recess of the watch case, the watch case must be provided with multiple grooves, such as a central groove, a pair of side grooves, and a transverse groove, which not only makes the structure complex, but also makes the task of mounting the decorative member cumbersome.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] BEST MODE FOR CARRYING OUT THE PRESENTLY PREFERRED EMBODIMENTS Hereinafter, one embodiment of a wristwatch to which the present invention is applied will be described with reference to FIGS. This wristwatch is an accessory worn on the wrist, and as shown in Figures 1 and 2, it has a wristwatch case 1 which is the accessory itself. This wristwatch case 1 is structured such that an upper case 1b is attached onto a lower case 1a via a waterproof ring 1c.

[0011] 1 and 2, band attachment sections 2 for attaching a watch band (not shown) are provided on the 12 o'clock and 6 o'clock sides of lower case 1a of wristwatch case 1. Switch sections 3 are provided on the 2 o'clock, 3 o'clock, 4 o'clock, 8 o'clock, and 10 o'clock sides of lower case 1a of wristwatch case 1 (the 8 o'clock and 10 o'clock sides are not shown).

[0012] 1 and 2, a watch crystal 4 is attached via a packing 4a to the upper opening of the watch case 1, i.e., the upper opening of the upper case 1b. A back cover (not shown) is attached to the lower part of the watch case 1. A watch module (not shown) is provided inside the watch case 1.

[0013] Meanwhile, at the top of this wristwatch case 1, that is, at the top of the upper case 1b, as shown in Figures 1 to 3, a mounting recess 6, which is an attachment portion for attaching a decorative body 5, is formed in a ring shape along the outer circumference of the wristwatch case 1. In this case, the top surface of the upper case 1b of the wristwatch case 1 is formed as a gently sloping surface that gradually becomes lower from the inner circumference side toward the outer circumference side. For this reason, the mounting recess 6 has a substantially square cross section, and is formed slightly deeper on the inner circumference side of the wristwatch case 1 than on the outer circumference side.

[0014] As shown in Figures 3 to 6, the decorative body 5 comprises a plurality of decorative members 7 made of a light-transmitting brittle material, and a holding member 8 into which the plurality of decorative members 7 are stacked and fitted. The holding member 8 is a thin metal plate 9 (see Figure 6(b)) made of stainless steel, titanium alloy, aluminum alloy, or the like, for example a metal plate 9 having a thickness of about 0.1 mm, and is formed into a ring shape as a whole.

[0015] 4 to 6, the retaining member 8 has a fitting recess 10 (fixing portion) having a recessed cross section formed by bending and raising the inner and outer circumferential portions of a ring-shaped metal plate 9. The fitting recess 10 is formed by a bottom portion 8a of the retaining member 8, a rising portion 8b on the inner circumferential side of the retaining member 8, and a rising portion 8c on the outer circumferential side of the retaining member 8, and is open upward.

[0016] 6(a) and 6(b), the inner peripheral rising portion 8b and the outer peripheral rising portion 8c of the retaining member 8 are provided with a plurality of notches 8d at predetermined intervals along the circumferential direction to facilitate bending the inner peripheral portion and the outer peripheral portion of the metal plate 9. The retaining member 8 is formed so that the distance between the outer surface of the inner peripheral rising portion 8b and the outer surface of the outer peripheral rising portion 8c, i.e., the radial length perpendicular to the circumferential direction of the bottom portion 8a, is the same as the radial length perpendicular to the circumferential direction of the mounting recess 6 of the wristwatch case 1.

[0017] 3 to 5, the holding member 8 is formed so that the rising portion 8b on the inner circumference side is slightly higher than the rising portion 8c on the outer circumference side. That is, the holding member 8 is formed so that the height of the rising portion 8b on the inner circumference side is slightly lower than the height of the inner circumferential surface of the mounting recess 6 located on the inner circumference side of the watch case 1, and the height of the rising portion 8c on the outer circumference side is the same as or slightly lower than the height of the inner circumferential surface of the mounting recess 6 located on the outer circumference side of the watch case 1.

[0018] As a result, when the retaining member 8 is fitted from above into the mounting recess 6 of the watch case 1, as shown in Figure 3, the bottom 8a is in close contact with the bottom surface of the mounting recess 6 of the watch case 1, the inner rising portion 8b approaches the inner surface of the mounting recess 6 located on the inner side of the watch case 1 at a slightly lower height, and the outer rising portion 8c approaches the inner surface of the mounting recess 6 located on the outer side of the watch case 1 at the same height or a slightly lower height.

[0019] In this case, the retaining member 8 is configured to be adhered and fixed in the mounting recess 6 of the wristwatch case 1 with an adhesive 11, as shown in Figures 3 and 4. That is, this adhesive 11 is applied in a slightly thick thickness to the bottom of the mounting recess 6 of the wristwatch case 1, and when the retaining member 8 is attached to the mounting recess 6, the adhesive 11 spreads from the underside of the bottom 8a of the retaining member 8 around to each of the outer surfaces of the rising portion 8b on the inner periphery of the retaining member 8 and the rising portion 8c on the outer periphery of the retaining member 8, adhering and fixing the retaining member 8 in the mounting recess 6.

[0020] For this reason, an adhesive reservoir 6a is provided below the vertical middle portion on the inner surface of the mounting recess 6, for storing adhesive 11 that has flowed from the underside of the bottom 8a of the holding member 8 to each of the outer surfaces of the rising portion 8b on the inner side of the holding member 8 and the rising portion 8c on the outer side of the holding member 8, as shown in Figures 3 and 4.

[0021] As a result, when the holding member 8 is mounted in the mounting recess 6 as shown in Figures 3 and 4, and the adhesive 11 flows from the underside of the bottom 8a of the holding member 8 to the outer surfaces of the rising portion 8b on the inner periphery of the holding member 8 and the rising portion 8c on the outer periphery of the holding member 8, the adhesive 11 accumulates in the adhesive reservoir portion 6a of the mounting recess 6 and does not leak out to the upper side of the mounting recess 6.

[0022] 3 to 5, a colored layer 10a for coloring the multiple decorative members 7 is provided on the inner surface of the fitting recess 10 of the holding member 8. That is, the colored layer 10a may be provided on the entire bottom surface and both side surfaces of the fitting recess 10, or may be provided on a part of the bottom surface and both side surfaces of the fitting recess 10. Although not shown, the colored layer 10a may be one of seven colors, such as red, orange, yellow, green, blue, indigo, and purple, or twelve colors, or may be partially different colors.

[0023] For example, although not shown, the colored layer 10a may be a different color in the left-right direction on the inner surface of the fitting recess 10, with a line connecting 12 o'clock and 6 o'clock as the boundary, or a different color in the up-down direction on the line connecting 3 o'clock and 9 o'clock as the boundary, or the inner surface of the fitting recess 10 may be divided into a plurality of parts, and the divided parts may be a different color. In this case, the colored layer 10a may be a different color in the parts corresponding to the hour characters representing 1 o'clock to 12 o'clock and the other parts, or each hour character may be a different color.

[0024] On the other hand, the plurality of decorative members 7 are shown in FIGS. To As shown in the figure, the decorative members 7 are made of brittle materials such as gemstones, such as sapphire, emerald, ruby, diamond, or other stones, highly transparent glass, such as quartz glass, or ceramics, which are transparent or translucent light-transmitting brittle materials. Each of the decorative members 7 is formed in a substantially flat ring shape having the same size as the fitting recess 10 of the holding member 8. In this embodiment, two decorative members 7 are stacked, but three or more may be stacked.

[0025] As shown in Figs. 3 to 5, a decorative layer 7a is provided on each of the front (upper surface) and back (lower surface) of the multiple decorative members 7. The decorative layers 7a are faceted layers such as cut glass, or thin film layers such as printed layers or vapor deposition layers having light transmission properties such as patterns or figures. As a result, when the multiple decorative members 7 are stacked, each decorative layer 7a can be seen from above, resulting in a three-dimensional decorative expression. In this case, the decorative layer 7a may be provided on all of the upper and lower surfaces of the multiple decorative members 7, or may be provided partially on either of the upper and lower surfaces of the multiple decorative members 7.

[0026] 3 to 5, each of the multiple decorative members 7 has chamfered portions 7b at each corner of the top and bottom surfaces. In this case, of the multiple decorative members 7, the topmost decorative member 7 has an upper surface that is formed into a gently sloping surface that gradually becomes lower from the inner periphery side to the outer periphery side, similar to the upper surface of the watch case 1. As a result, the multiple decorative members 7 are formed so that when they are stacked one on top of the other, the height of the inner periphery side is higher than the height of the outer periphery side.

[0027] 3 and 4, the multiple decorative members 7 are temporarily fixed with a transparent or semi-transparent adhesive (not shown) in a state where the decorative layers 7a on the top and bottom surfaces are aligned when stacked one on top of the other. Therefore, when the multiple decorative members 7 are stacked one on top of the other and fitted into the fitting recess 10 of the holding member 8, the top surface of the topmost decorative member 7 is inclined, and the portion of the topmost decorative member 7 that corresponds to the chamfered portion 7b on the top surface side protrudes above the fitting recess 10.

[0028] In other words, when the multiple decorative members 7 are stacked and fitted into the fitting recess 10 of the retaining member 8, as shown in Figures 3 and 4, the upper end portion corresponding to the chamfered portion 7b on the inner circumference on the upper surface of the top decorative member 7 is positioned protruding above the raised portion 8b on the inner circumference side of the fitting recess 10.

[0029] Similarly, as shown in Figures 3 and 4, when multiple decorative members 7 are stacked and fitted into the fitting recess 10 of the retaining member 8, the upper end portion roughly corresponding to the chamfered portion 7b on the outer periphery of the upper surface of the top decorative member 7 is configured to protrude above the rising portion 8c on the outer periphery side of the fitting recess 10.

[0030] 2 and 3, the decorative body 5 is configured so that when the retaining member 8 is attached within the mounting recess 6 of the watch case 1, the upper surface of the uppermost decorative member 7 protruding above the fitting recess 10 of the retaining member 8 is positioned at an angle and on approximately the same plane as the upper surface of the watch case 1. In other words, this decorative body 5 is configured so that even if the height of the retaining member 8 is slightly lower than the depth of the mounting recess 6 of the watch case 1, the upper surface of the uppermost decorative member 7 is positioned on approximately the same plane as the upper surface of the watch case 1.

[0031] 3 to 5, when the multiple decorative members 7 are stacked and fitted into the fitting recess 10 of the holding member 8, they are configured to be fixed into the fitting recess 10 by a fixing portion 12, which is a member fixing portion. That is, the fixing portion 12 includes a locking protrusion 12a that is provided on a rising portion 8c on the outer periphery of the holding member 8, which is the inner surface of the fitting recess 10, and protrudes toward the inside of the fitting recess 10, and an engaging recess 12b that is provided along the circumferential direction on the outer periphery of the uppermost decorative member 7 and engages with the locking protrusion 12a of the fitting recess 10.

[0032] As a result, as shown in Figures 3 to 5, when multiple decorative members 7 are fitted into the fitting recess 10 of the holding member 8 in a stacked state, the fixing portion 12 is configured so that the locking protrusion 12a protruding toward the inside of the fitting recess 10 engages with the engagement recess 12b provided on the outer surface of the top decorative member 7, thereby fixing the multiple decorative members 7 in a stacked state within the fitting recess 10.

[0033] 3 to 5, the decorative members 7 are stacked and fitted into the fitting recesses 10 of the holding member 8, and are also fixed into the fitting recesses 10 by an ultraviolet-curing resin 13, which is a photocurable resin, as an adhesive. That is, the ultraviolet-curing resin 13 has light transmittance such as transparency or translucency, and is cured when irradiated with ultraviolet light. The ultraviolet-curing resin 13 is applied to almost the entire inner surface of the fitting recesses 10 of the holding member 8.

[0034] Therefore, as shown in Figures 3 to 5, when multiple decorative members 7 are stacked and fitted into the fitting recess 10 of the holding member 8 and ultraviolet light is irradiated from above the topmost decorative member 7, the irradiated ultraviolet light passes through the multiple decorative members 7 and is irradiated onto the ultraviolet-cured resin 13, causing the ultraviolet-cured resin 13 to harden, fixing the multiple stacked decorative members 7 in the fitting recess 10 and preventing misalignment due to circumferential rattling of the multiple decorative members 7.

[0035] Next, a method for manufacturing such a wristwatch will be described. The manufacturing method for this wristwatch includes a first step of forming a retaining member 8 by bending a metal plate 9 to form an attachment recess 10, a second step of forming a decorative body 5 by stacking, fitting and fixing a plurality of decorative members 7 into the attachment recess 10 of the retaining member 8, and a third step of attaching the decorative body 5 to the mounting recess 6 of the wristwatch case 1.

[0036] That is, in the first step, as shown in Figures 6(a) and 6(b), the locking protrusions 12a (see Figure 5) of the fixing part 12 are formed in advance by pressing at locations corresponding to the outer peripheral rising part 8c located on the outer peripheral side of the bottom part 8a of the ring-shaped metal plate 9. At the same time, a plurality of notches 8d are provided at predetermined intervals along the circumferential direction at locations corresponding to the inner peripheral rising part 8b and the outer peripheral rising part 8c located on the inner peripheral side and outer peripheral side of the bottom part 8a of the metal plate 9.

[0037] 5 and 6, the inner peripheral portion and the outer peripheral portion of the metal plate 9 are raised by a bending process such as press working, thereby forming rising portions 8b, 8c on the inner peripheral portion and the outer peripheral portion of the metal plate 9 at a location corresponding to the bottom portion 8a. At this time, the rising portion 8b on the inner peripheral side and the rising portion 8c on the outer peripheral side of the bottom portion 8a of the metal plate 9 are easily and satisfactorily bent by a plurality of notches 8d provided at locations corresponding to the rising portion 8b on the inner peripheral side and the rising portion 8c on the outer peripheral side.

[0038] As a result, in the first step, a holding member 8 is formed in which a fitting recess 10 that is open upward is formed by a bottom portion 8a of the metal plate 9, a rising portion 8b on the inner periphery side of the metal plate 9, and a rising portion 8c on the outer periphery side of the metal plate 9. At this time, a locking protrusion 12a is provided on the rising portion 8c on the outer periphery side of the holding member 8, which is the inner surface of the fitting recess 10, so as to protrude toward the inside of the fitting recess 10.

[0039] In this first step, a colored layer 10a for coloring the multiple decorative members 7 is provided on the inner surface of the fitting recess 10 of the holding member 8. This colored layer 10a may be provided on the entire bottom surface and both side surfaces of the fitting recess 10, or may be provided on parts of the bottom surface and both side surfaces of the fitting recess 10. In this case, the colored layer 10a may be a single color, or may be partially different colors.

[0040] For example, the colored layer 10a may be different colors in the left-right direction on the inner surface of the fitting recess 10, with the line connecting 12 o'clock and 6 o'clock as the boundary, or different colors in the up-down direction on the line connecting 3 o'clock and 9 o'clock as the boundary, or the inner surface of the fitting recess 10 may be divided into multiple parts, and these divided parts may be different colors. In this case, the colored layer 10a may be different colors in the parts corresponding to the hour characters representing 1 o'clock to 12 o'clock and other parts, or each hour character may be a different color.

[0041] In the second step, when fitting the multiple decorative members 7 into the fitting recesses 10 of the holding member 8, an engagement recess 12b is formed in advance on the outer peripheral surface of the uppermost decorative member 7, and the multiple decorative members 7 are stacked. At this time, the decorative layers 7a provided on the upper and lower surfaces of the multiple decorative members 7 are aligned, and the multiple decorative members 7 are stacked so that the decorative patterns and decorative figures formed by the decorative layers 7a are expressed three-dimensionally. In this state, the multiple stacked decorative members 7 are bonded and temporarily fixed with a light-transmitting adhesive (not shown), such as a transparent or semi-transparent adhesive.

[0042] When fitting the multiple stacked decorative members 7 into the fitting recesses 10 of the holding member 8, an ultraviolet-curing resin 13, which is a light-curing resin having optical transparency, is applied in advance to almost the entire inner surface of the fitting recesses 10. In this state, the multiple stacked decorative members 7 are fitted into the fitting recesses 10 of the holding member 8. Then, the locking protrusions 12a provided on the rising portion 8c on the outer periphery of the holding member 8 engage with the engagement recesses 12b provided on the outer periphery of the uppermost decorative member 7 among the multiple stacked decorative members 7, and the multiple stacked decorative members 7 are fixed in the fitting recesses 10 of the holding member 8.

[0043] At this time, the ultraviolet-curing resin 13 applied to almost the entire inner surface of the fitting recess 10 has not hardened and is fluid, so when the stacked decorative members 7 are fitted into the fitting recess 10 of the holding member 8, the stacked decorative members 7 are fitted into the fitting recess 10 of the holding member 8 smoothly and well without being affected by the ultraviolet-curing resin 13.

[0044] In this state, when ultraviolet light is irradiated from above the topmost decorative member 7, the irradiated ultraviolet light passes through the stacked decorative members 7 and is irradiated onto the ultraviolet curing resin 13 applied to the inner surface of the fitting recess 10. The irradiated ultraviolet light then hardens the ultraviolet curing resin 13, and the stacked decorative members 7 are fixed in the fitting recess 10 of the holding member 8 by this hardened ultraviolet curing resin 13, preventing misalignment due to circumferential rattling of the decorative members 7. In this way, the decorative body 5 is formed.

[0045] In the third step, the decorative body 5 is attached and fixed in the mounting recess 6 of the watch case 1. At this time, as shown in Fig. 4, a thick layer of adhesive 11 is applied to the bottom side of the inner surface of the mounting recess 6 of the watch case 1 in advance, and in this state the holding member 8 of the decorative body 5 is fitted into the mounting recess 6 of the watch case 1. Then, the adhesive 11 flows from the underside of the bottom 8a of the holding member 8 to the outer surfaces of the rising portion 8b on the inner periphery side of the holding member 8 and the rising portion 8c on the outer periphery side of the holding member 8.

[0046] 3, this leaking adhesive 11 accumulates in adhesive reservoir 6a provided at a location below the vertical middle portion on the inner circumferential surface of mounting recess 6. As a result, holding member 8 is mounted in mounting recess 6 and fixed by adhesive 11. At this time, even if adhesive 11 leaks from the underside of bottom 8a of holding member 8 to each of the outer surfaces of rising portion 8b on the inner circumferential side of holding member 8 and rising portion 8c on the outer circumferential side of holding member 8, adhesive 11 does not leak out to the upper side of mounting recess 6 because it accumulates in adhesive reservoir 6a of mounting recess 6.

[0047] Next, the function of such a wristwatch ornament 5 will be described. In this decorative body 5, multiple decorative members 7 made of a light-transmitting brittle material are stacked and arranged in the fitting recess 10 of the holding member 8, so that the decorative layers 7a provided on the upper and lower surfaces of the multiple decorative members 7 can be seen from above, providing a three-dimensional decorative expression. This enhances the decorativeness.

[0048] In this case, the colored layer 10a is provided on the inner surface of the fitting recess 10 of the holding member 8, and the multiple decorative members 7 stacked in the fitting recess 10 of the holding member 8 are colored by this colored layer 10a. This also enhances the decorativeness. In this case, the colored layer 10a may be provided in a single color on almost the entire inner surface of the fitting recess 10, and the multiple decorative members 7 may be colored in a single color, or the colored layer 10a may be provided in different colors partially on the inner surface of the fitting recess 10, and the multiple decorative members 7 may be colored in different colors partially.

[0049] For example, the colored layer 10a may be colored differently in the left-right direction along the line connecting 12 o'clock and 6 o'clock on the inner surface of the fitting recess 10, so that the multiple decorative members 7 are colored differently in the left-right direction, or the colored layer 10a may be colored differently in the up-down direction along the line connecting 3 o'clock and 9 o'clock, so that the multiple decorative members 7 are colored differently in the up-down direction. Also, the colored layer 10a may be formed by dividing the inner surface of the fitting recess 10 into multiple parts, and the divided parts may be colored differently, so that the multiple decorative members 7 are colored partially in different colors. These methods also enhance the decorativeness.

[0050] Thus, with this wristwatch, there is provided a decorative member 7 made of a brittle material, a retaining member 8 having a fitting recess 10 into which the decorative member 7 is fitted and fixed, and a wristwatch case 1 which is the main body of the accessory having a mounting recess 6 which is an attachment portion into which the retaining member 8 is attached, thereby making it possible to easily attach the decorative member 7 with a simple structure.

[0051] In other words, in this wristwatch, the only thing that needs to be done is to provide the wristwatch case 1 with an attachment recess 6 into which the retaining member 8 is attached, so the structure of the wristwatch case 1 is simple and can be easily manufactured, and since the decorative member 7 is simply fitted and fixed into the fitting recess 10 of the retaining member 8, the decorative member 7 can be simply and easily attached to the retaining member 8, and this retaining member 8 can be easily attached to the attachment recess 6 of the wristwatch case 1, so that the decorative member 7 can be easily attached to the wristwatch case 1 by the retaining member 8.

[0052] Furthermore, in this watch, since the decorative member 7 is light-transmitting, the decorative member 7 can be seen through, and therefore even if a decorative layer 7a is applied to the back surface (lower surface) of the decorative member 7, the decorative layer 7a can be seen from the front surface (upper surface) of the decorative member 7. Furthermore, if a colored layer 10a is provided on the inner surface of the fitting recess 10 of the holding member 8, the decorative member 7 can be colored by this colored layer 10a, thereby enhancing the decorativeness.

[0053] In this case, in this wristwatch, by providing the decorative layers 7a on the upper and lower surfaces of the decorative member 7, a three-dimensional decorative expression can be achieved by the upper decorative layer 7a and the lower decorative layer 7a, thereby further enhancing the decorativeness. In other words, the upper decorative layer 7a and the lower decorative layer 7a are separated in the vertical direction by the thickness of the decorative member 7, so that a three-dimensional decorative expression can be achieved by the upper and lower decorative layers 7a.

[0054] Furthermore, in this wristwatch, the decorative members 7 are stacked in multiple layers within the fitting recess 10 of the holding member 8, so that each stacked decorative member 7 can have a different decorative expression, and the stacked decorative members 7 as a whole can have a three-dimensional decorative expression. In other words, the multiple decorative layers 7a provided on the top and bottom surfaces of the multiple decorative members 7 can provide an even more three-dimensional decorative expression, thereby providing a highly decorative watch.

[0055] Also, in this wristwatch, the fitting recess 10 of the retaining member 8 is formed by bending the metal plate 9, so that the thickness of the metal plate 9 can be reduced, thereby making it possible to reduce the thickness of the retaining member 8 and easily manufacture the fitting recess 10. That is, the retaining member 8 has a plurality of cutout portions 8d provided at predetermined intervals along the circumferential direction at locations corresponding to the rising portion 8b on the inner circumference side and the rising portion 8c on the outer circumference side of the ring-shaped metal plate 9, so that even if the metal plate 9 is a ring-shaped flat plate, the rising portions 8b, 8c on the inner circumference side and the outer circumference side of the retaining member 8 can be easily formed by bending.

[0056] Furthermore, in this watch, the inner surface of the fitting recess 10 is colored with the colored layer 10a, so that the light-transmitting decorative member 7 can be colored, thereby also enhancing the decorativeness. In this case, in this watch, the colored layer 10a may be provided in a single color on almost the entire inner surface of the fitting recess 10, so that the entire decorative member 7 is colored in a single color, or the colored layer 10a may be provided in different colors partially on the inner surface of the fitting recess 10, so that the entire decorative member 7 is colored in different colors partially.

[0057] That is, in this wristwatch, for example, the colored layer 10a may be colored differently in the left-right direction on the inner surface of the fitting recess 10, with the line connecting 12 o'clock and 6 o'clock as the boundary, so that the entire decorative member 7 is colored differently in the left-right direction, or the colored layer 10a may be colored differently in the up-down direction on the line connecting 3 o'clock and 9 o'clock as the boundary, so that the entire decorative member 7 is colored differently in the up-down direction. Also, the colored layer 10a may be formed by dividing the inner surface of the fitting recess 10 into multiple parts, and these multiple divided parts may be colored different colors, so that the entire decorative member 7 is colored partially in different colors. These methods can also enhance the decorativeness.

[0058] Furthermore, this wristwatch is provided with fixing parts 12 that fix decorative member 7 within fitting recess 10 of holding member 8, and this fixing part 12 allows decorative member 7 to be reliably and satisfactorily fixed within fitting recess 10 of holding member 8. In this case, with this wristwatch, even if multiple decorative members 7 are stacked, these stacked decorative members 7 can be reliably and satisfactorily fixed within fitting recess 10 of holding member 8 by fixing parts 12.

[0059] In other words, in this wristwatch, the fixing portion 12 is equipped with a locking protrusion 12a provided on the inner surface of the fitting recess 10 and an engagement recess 12b provided on the outer peripheral surface of the decorative member 7 with which the locking protrusion 12a engages. Therefore, when the decorative member 7 is fitted into the fitting recess 10, the locking protrusion 12a of the fitting recess 10 can be engaged with the engagement recess 12b of the decorative member 7, so that the decorative member 7 can be easily and securely fixed into the fitting recess 10 of the holding member 8.

[0060] In addition, the manufacturing method of this wristwatch includes a first step of forming a retaining member 8 by bending a metal plate 9 to form a fitting recess 10, a second step of fitting and fixing a decorative member 7 made of a brittle material into the fitting recess 10 of the retaining member 8, and a third step of attaching the retaining member 8 with the decorative member 7 fitted into the mounting recess 6, which is the attachment part of the wristwatch case 1, which is the main body of the jewelry, so that the decorative member 7 can be easily and satisfactorily attached to the wristwatch case 1 by the retaining member 8.

[0061] In this case, in the first step, a plurality of notches 8d are provided in advance at predetermined intervals along the circumferential direction at locations corresponding to the inner peripheral rising portion 8b and the outer peripheral rising portion 8c located on the inner peripheral side and outer peripheral side of the bottom portion 8a of the ring-shaped, flat metal plate 9, and in this state, the inner peripheral portion and the outer peripheral portion of the metal plate 9 are raised by a bending process such as press working, so that the rising portions 8b, 8c can be easily and satisfactorily formed on the inner peripheral portion and the outer peripheral portion of the metal plate 9 at the locations corresponding to the bottom portion 8a.

[0062] That is, at this time, even if the metal plate 9 is a ring-shaped flat plate, the inner peripheral rising portion 8b and the outer peripheral rising portion 8c of the ring-shaped metal plate 9 can be easily and satisfactorily folded due to the multiple notches 8d provided at locations corresponding to the inner peripheral rising portion 8b and the outer peripheral rising portion 8c located on the inner peripheral side and the outer peripheral side of the bottom portion 8a of the metal plate 9. As a result, the fitting recess 10 that is open upward can be accurately and satisfactorily formed by the bottom portion 8a of the metal plate 9, the inner peripheral rising portion 8b of the metal plate 9, and the outer peripheral rising portion 8c of the metal plate 9.

[0063] In addition, in the second process, the decorative layers 7a provided on each of the front and back surfaces (top and bottom surfaces) of the multiple decorative members 7 are aligned, and the multiple decorative members 7 are stacked so that the decorative patterns and decorative figures provided by each decorative layer 7a are expressed three-dimensionally, and in this state, the multiple decorative members 7 can be temporarily fixed by adhering them together with an adhesive (not shown) that is light-transmitting, such as transparent or translucent.

[0064] Therefore, in this second step, when the stacked decorative members 7 are fitted into the fitting recesses 10 of the holding member 8, the engaging recess 12b of the fixing portion 12 provided on the outer peripheral surface of the topmost decorative member 7 among the stacked decorative members 7 can be engaged with the locking protrusion 12a of the fixing portion 12 provided on the rising portion 8c of the outer peripheral portion of the holding member 8, so that the stacked decorative members 7 can be reliably and satisfactorily fixed within the fitting recesses 10 of the holding member 8.

[0065] In the third step, the retaining member 8 of the decorative body 5 is adhered and fixed in the mounting recess 6 of the watch case 1 with adhesive 11. At this time, the adhesive 11 is applied thickly to the bottom side of the inner surface of the mounting recess 6 of the watch case 1 in advance, and in this state the retaining member 8 of the decorative body 5 can be fitted into the mounting recess 6 of the watch case 1. In this case, the adhesive 11 wraps around from the underside of the bottom 8a of the retaining member 8 to the outer surfaces of the rising portion 8b on the inner periphery side of the retaining member 8 and the rising portion 8c on the outer periphery side of the retaining member 8.

[0066] At this time, the adhesive 11 that has flowed around can be stored in adhesive reservoir 6a provided at a location below the vertical middle part on the inner circumferential surface of mounting recess 6, so that adhesive 11 does not leak out to the upper side of mounting recess 6. This allows holding member 8 to be mounted in mounting recess 6 and reliably and satisfactorily fixed by adhesive 11.

[0067] In the above-described embodiment, the fixing portion 12 for fixing the decorative member 7 in the fitting recess 10 of the holding member 8 is described as having a locking protrusion 12a provided in the fitting recess 10 and an engaging recess 12b provided in the decorative member 7. However, the present invention is not limited to this, and may have a structure in which, for example, a locking recess is provided in the fitting recess 10 and an engaging protrusion is provided in the decorative member 7.

[0068] In addition, in the above-described embodiment, a case has been described in which multiple stacked decorative members 7 are fixed in the fitting recess 10 of the holding member 8 by engagement between the locking protrusion 12a and the engagement recess 12b of the fixing portion 12. However, the present invention is not limited to this, and the multiple stacked decorative members 7 may also be configured to be fixed in the fitting recess 10 of the holding member 8 by a clamp portion 15, which is a member fixing portion such as the modified example shown in Figure 7.

[0069] 7, the clamp portion 15 of this modified example is, for example, a crimped portion provided on the upper end of the rising portion 8b on the outer periphery of the holding member 8. The clamp portion 15 as a crimped portion may be configured such that, with a plurality of decorative members 7 stacked and fitted into the fitting recesses 10 of the holding member 8, the upper end of the rising portion 8b on the outer periphery of the holding member 8 is crimped, thereby fixing the plurality of decorative members 7 in the stacked state within the fitting recesses 10 of the holding member 8.

[0070] 7, the clamping portion 15 of this modified example is, for example, a leaf spring portion provided at the upper end of the rising portion 8b on the outer periphery of the holding member 8. The clamping portion 15, which is a leaf spring portion, may be configured such that when multiple decorative members 7 are stacked and fitted into the fitting recess 10 of the holding member 8, when the multiple decorative members 7 are fitted against the spring force of the leaf spring portion at the upper end of the rising portion 8b on the outer periphery of the holding member 8, the uppermost decorative member 7 of the multiple stacked decorative members 7 is pressed down by the spring force of the leaf spring portion, thereby fixing the multiple stacked decorative members 7 in the fitting recess 10 of the holding member 8.

[0071] In the above embodiment, the ultraviolet curable resin 13 is used as the light-transmitting light-curing resin for fixing the multiple decorative members 7 in the fitting recesses 10 of the holding member 8, but the present invention is not limited to this, and for example, an infrared curable resin having light transmittance may be used. This infrared curable resin hardens when irradiated with infrared rays.

[0072] In the above embodiment, the holding member 8 of the ornament 5 is fixed in the mounting recess 6 of the watch case 1 by adhering it with the adhesive 11, but the present invention is not limited to this, and the holding member 8 of the ornament 5 may be fixed in the mounting recess 6 of the watch case 1 by adhering it with, for example, a double-sided adhesive tape. In this case, since the double-sided adhesive tape has no fluidity, there is no need to provide an adhesive reservoir 6a on the inner surface of the mounting recess 6.

[0073] In addition, in the above-described embodiment, the decorative member 7 has a structure in which multiple layers are laminated, but the present invention does not necessarily require the decorative member 7 to have a structure in which multiple layers are laminated, and for example, the decorative member 7 may have a structure in which only one layer is laminated.

[0074] Furthermore, while the above-described embodiment has been described as being applied to a wristwatch, the present invention does not necessarily have to be applied to a wristwatch, but can also be applied to accessories such as bracelets, brooches, pendants, necklaces, and earrings.
