Description

[Technical field]

[0001] The present invention relates to a timepiece dial and a timepiece. [Background technology]

[0002] A convex protrusion may be formed on the surface of a timepiece dial. The protrusion serves as an index indicating, for example, the time. A resin layer may be formed on the surface of the dial (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2-189493 Summary of the Invention [Problem to be solved by the invention]

[0004] The dial requires high precision in its formation since it is necessary to combine other parts with it. The resin layer is formed by applying uncured resin to the surface of the dial and curing it. When forming the resin layer, the resin may overflow from a predetermined area on the dial, resulting in a low precision in the formation of the resin layer. If the shape of the resin layer is distorted, a part of the resin layer may interfere with the case, the second hand, etc. In particular, when a transparent resin is used, a distorted shape of the resin layer may not be noticed until the assembly of the watch is completed, resulting in low production efficiency. For these reasons, there is a demand for improved precision in the formation of the resin layer in watch dials.

[0005] An object of one aspect of the present invention is to provide a timepiece dial and a timepiece that can improve the accuracy of forming a resin layer. [Means for solving the problem]

[0006] (1) A timepiece dial comprising: a substrate having a first main surface on which a protrusion having an end face and a wall portion are formed to protrude; a printed layer formed on the end face; and a resin layer having a second main surface located higher than the first main surface and formed in at least a portion of an area of ​​the first main surface where the protrusion is not formed.

[0007] According to this configuration, the resin filled in the resin layer can be prevented from spilling out of the substrate during the process of forming the resin layer. Therefore, the resin layer is less likely to be distorted in shape due to the resin spilling out. This makes it possible to improve the accuracy of forming the resin layer. This makes it possible to improve the quality of the appearance of the timepiece dial.

[0008] (2) The timepiece dial according to (1), wherein the wall portion is formed on at least one of the inner peripheral edge and the outer peripheral edge of the substrate.

[0009] According to this configuration, in the process of forming the resin layer, it is possible to prevent the resin from spilling out from the substrate. For example, if there is a wall portion on the outer periphery, it is possible to prevent the resin from spilling out from the substrate to the outside. If there is a wall portion on the inner periphery, it is possible to prevent the resin from spilling in from the substrate to the inside. Therefore, it is possible to improve the accuracy of forming the resin layer.

[0010] (3) The timepiece dial according to (1) or (2), wherein the height position of the second main surface is equal to the height position of the end surface.

[0011] This configuration makes it possible to prevent the screen from warping during the manufacture of the timepiece dial, thereby improving the accuracy of forming the print layer.

[0012] (4) A timepiece dial according to any one of (1) to (3), wherein the periphery of the printed layer is located inside the periphery of the end face when viewed from a direction perpendicular to the end face.

[0013] With this configuration, even if the position of the printed layer is shifted, as long as the shift is not too large, the printed layer will be contained within the area of ​​the end face of the index, making the positional shift of the printed layer less noticeable.

[0014] (5) A timepiece dial described in any one of (1) to (4), in which a base layer is formed on the end surface, the printing layer is formed on the surface of the base layer, and the periphery of the printing layer is located inside the periphery of the base layer when viewed from a direction perpendicular to the end surface.

[0015] According to this configuration, even if the formation position of the printed layer is misaligned, the printed layer will be contained within the area of ​​the base layer as long as the misalignment is not large. Therefore, the misalignment of the printed layer is difficult to visually recognize. Therefore, the misalignment of the printed layer can be made inconspicuous.

[0016] (6) A timepiece dial described in any one of (1) to (4), in which a base layer is formed on the end surface, the printing layer is formed on the surface of the base layer, and the periphery of the printing layer is located inside the periphery of the base layer when viewed from a direction perpendicular to the end surface.

[0017] According to this configuration, even if the formation position of the printed layer is misaligned, the printed layer will be contained within the area of ​​the base layer as long as the misalignment is not large. Therefore, the misalignment of the printed layer is difficult to visually recognize. Therefore, the misalignment of the printed layer can be made inconspicuous.

[0018] (7) The timepiece dial according to any one of (1) to (6), wherein the resin layer has a plurality of layers in the thickness direction.

[0019] This configuration allows for greater freedom in designing the appearance of the timepiece dial. For example, the reflection at the boundaries between multiple layers can produce a three-dimensional, deep visual effect, improving the aesthetics of the timepiece dial.

[0020] (8) The timepiece dial according to any one of (1) to (7), wherein the resin layer has optical transparency.

[0021] This configuration improves the aesthetic appearance of the timepiece dial.

[0022] (9) The timepiece dial according to any one of (1) to (8), wherein the resin layer is partitioned into a plurality of regions in a plan view.

[0023] This configuration allows for a wide variety of expressions, thereby improving the aesthetic appearance of the timepiece dial.

[0024] (10) The timepiece dial according to any one of (1) to (9), wherein the resin layer has a design feature.

[0025] This configuration improves the aesthetic appearance of the timepiece dial.

[0026] (11) A watch having a watch dial according to any one of (1) to (10).

[0027] With this configuration, the resin layer is less likely to be distorted in shape due to resin overflow, which makes it possible to increase the precision with which the resin layer is formed, thereby improving the quality of the appearance of the timepiece dial. Effect of the Invention

[0028] According to one aspect of the present invention, it is possible to provide a timepiece dial and a timepiece that can improve the formation accuracy of the print layer formed on the index. [Brief description of the drawings]

[0030] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0031] [clock] Fig. 1 is a cross-sectional view of a timepiece 1 according to an embodiment. Fig. 2 is a plan view of a portion of the dial 3. Fig. 3 is a cross-sectional view of the dial 3. Fig. 3 is a cross-sectional view taken along line II in Fig. 2. Fig. 4 is a plan view of an index 23. Fig. 5 is a schematic diagram showing a cross-section of the index 23. Fig. 5 is a schematic diagram showing the II-II cross-section in Fig. 4.

[0032] As shown in FIG. 1, the timepiece 1 comprises a timepiece case 2, a dial 3, hands 4, a timepiece movement 5, and a rotary operating unit 7.

[0033] The watch case 2 (case) comprises a case body 10, a crystal 11, a bezel 12, and a back cover 13. The case body 10 is formed in a cylindrical shape. The crystal 11 closes one opening of the case body 10. The bezel 12 is provided at one opening end of the case body 10. The back cover 13 closes the other opening of the case body 10. The watch case 2 houses a dial 3, hands 4, and a movement 5.

[0034] Below, the position of each component is provisionally determined based on Fig. 1. For example, the crystal 11 is positioned above the back cover 13. The positions shown here do not limit the position of the timepiece 1 when in use.

[0035] The hands 4 are disposed between the dial 3 and the glass 11. The hands 4 are attached to a rotation shaft 14 of the movement 5. The movement 5 is disposed between the dial 3 and the back cover 13. The movement 5 includes a drive source that drives the rotation shaft 14. The rotation shaft 14 extends from the center of the dial 3 in a direction perpendicular to the dial 3.

[0036] The rotary operation unit 7 includes a rotary shaft portion 71 and a head portion 72. The rotary operation unit 7 (crown) rotates components within the movement 5.

[0037] [Clock dial] (First embodiment) As shown in Fig. 2, the dial 3 (timepiece dial) according to the first embodiment is formed in a circular plate shape. The dial 3 can be seen through a glass 11 (see Fig. 1). Viewing the dial 3 from a direction perpendicular to the dial 3 is called a plan view.

[0038] The left-right direction in FIG. 2 is the X direction. The X direction is a direction along the top surface 21a of the substrate 21, and passes through the 3 o'clock and 9 o'clock positions of the dial 3. The up-down direction in FIG. 2 is the Y direction. The Y direction is a direction along the top surface 21a of the substrate 21, and is perpendicular to the X direction. The Y direction is a direction passing through the 6 o'clock and 12 o'clock positions of the dial 3. The plane defined by the X and Y directions is the XY plane. The Z direction is a direction perpendicular to the X and Y directions. The Z direction is the up-down direction (height direction). Viewing from the Z direction is called "planar view."

[0039] The dial 3 is formed of, for example, one or more of metal, ceramic, glass, and plastic. Examples of metals constituting the dial 3 include one or more of (A) copper, (B) iron, (C) titanium, (D) gold, (E) silver, (F) platinum, and (G) nickel, or alloys containing one or more of (A) to (G) as main components. A "main component" is, for example, a component that accounts for more than 50% by mass of the whole. Using these materials makes it easier to process the dial 3 and reduces costs.

[0040] A central hole 3c through which the rotary shaft 14 is inserted is formed in the center of the dial 3. The central hole 3c passes through the dial 3 in the thickness direction.

[0041] The dial 3 has a substrate 21 and a resin layer 22 . A plurality of indexes 23 are formed on the top surface 21a (first main surface), which is one surface of the substrate 21. The indexes 23 are, for example, indicators that show the time. The plurality of indexes 23 are, for example, formed at positions close to the outer periphery of the dial 3, spaced apart in the circumferential direction of the dial 3. The plurality of indexes 23 are, for example, formed at the 1 o'clock to 12 o'clock positions, respectively. The indexes 23 are formed integrally with the substrate 21. The indexes 23 are an example of a "protrusion".

[0042] The shape of the index 23 is not particularly limited. The index 23 has the shape of, for example, a figure, a letter, a symbol, or the like. The index 23 may be, for example, in a plan view, a bar shape extending along the radial direction of the dial 3, or may be a circle, a polygon (for example, a triangle, a rectangle, a trapezoid), or a number (Arabic numerals, Roman numerals, etc.). The index 23 is also called an hour mark.

[0043] In this embodiment, of the twelve indexes 23 formed at the 1 to 12 o'clock positions, the indexes 23 formed at the 12, 3, 6, and 9 o'clock positions are trapezoidal in shape with a gradually narrower width toward the inside in the radial direction in plan view. The remaining indexes 23 are circular in plan view.

[0044] 3, the index 23 is formed to protrude upward from the upper surface 21a of the substrate 21. The index 23 has an end surface 23a (upper surface). The end surface 23a is parallel to the XY plane. The cross-sectional shape of the index 23 may be, for example, rectangular. The cross-sectional shape of the index 23 may also be a trapezoid whose width increases downward.

[0045] The height of the index 23 from the upper surface 21a is preferably 0.03 mm or more (for example, 0.1 mm or more). By setting the height of the index 23 within this range, the visibility of the index 23 can be improved.

[0046] The index 23 (protrusion) is different from the pattern of projections and recesses formed on the upper surface 21a. When a pattern is formed on the upper surface 21a, the height of the index 23 may be the height from the top of the pattern.

[0047] The method of forming the index 23 is not particularly limited. The index 23 can be formed in a convex shape by pressing the substrate 21 or the like. The index 23 can also be formed by cutting the surface of the substrate 21 when it is manufactured. When the substrate 21 is made of plastic or the like, the index 23 can also be formed by a molding method such as injection molding. The index 23 can also be formed by electroforming or transfer printing.

[0048] As shown in Figs. 4 and 5, a printing layer 24 is formed on the end surface 23a of the index 23. If the printing layer 24 has a color different from that of the substrate 21, the visibility of the printing layer 24 can be improved. The printing layer 24 includes, for example, a phosphorescent material. The phosphorescent material absorbs energy upon receiving a light stimulus, converts the absorbed energy into visible light, and emits light even after the stimulus has stopped. By employing the printing layer 24 including a phosphorescent material, the index 23 can be easily viewed even in a dark place. The printing layer 24 may include a fluorescent material.

[0049] In a plan view (i.e., viewed from a direction perpendicular to the end face 23a), the printed layer 24 is preferably formed on a part of the end face 23a, rather than on the entire end face 23a. The periphery 24a of the printed layer 24 is preferably located inside the periphery 23b of the end face 23a.

[0050] The printing layer 24 is formed on the index 23 via a base layer 25 . The base layer 25 is formed on the end surface 23a of the index 23. The base layer 25 is formed of paint or the like. The base layer 25 can be formed by printing or the like. The base layer 25 may also be formed by plating or the like. For example, the base layer 25 may be formed only on the indexes 23 at the 12 o'clock, 3 o'clock, 6 o'clock, and 9 o'clock positions out of the twelve indexes 23.

[0051] It is desirable that the undercoat layer 25 has a similar color to the printed layer 24. Similar colors can be specified, for example, in accordance with JIS Z8721 (color display method-display by three attributes). The criteria for determining whether or not the colors are similar can be that the hues are adjacent to each other on the hue circle and that the lightness and saturation are each within a range of ±3. For example, when the first color has a hue of 5R, a lightness of 4, and a saturation of 6, if the hue of the second color is in the range of 2.5R to 7.5R, the lightness is 1 to 7, and the saturation is in the range of 3 to 9, the first color and the second color are similar colors. When the first color is achromatic, if the second color is achromatic and the lightness is within a range of ±3 to the first color, the first color and the second color are similar colors. When the undercoat layer 25 has a similar color to the printed layer 24, if the printed layer 24 is misaligned, the misalignment can be made less noticeable.

[0052] In a plan view, the base layer 25 is preferably formed not over the entire area of ​​the end face 23a but over a part of the end face 23a. It is desirable that the periphery 25a of the base layer 25 is located inside the periphery 23b of the end face 23a.

[0053] In a plan view, the printed layer 24 is preferably formed on a part of the surface of the base layer 25, rather than on the entire surface area of ​​the base layer 25. It is desirable that the peripheral edge 24a of the printed layer 24 is located inside the peripheral edge 25a of the base layer 25.

[0054] As shown in FIG. 3, an outer peripheral wall 31 and an inner peripheral wall 32 are formed on an upper surface 21a of the substrate 21. The outer peripheral wall 31 protrudes upward from the outer peripheral edge of the substrate 21. The outer peripheral wall 31 is formed in an annular shape. The inner peripheral wall 32 protrudes upward from the peripheral edge of the central hole 3c (the inner peripheral edge of the substrate 21). The inner peripheral wall 32 is formed in annular shape. The outer peripheral wall 31 and the inner peripheral wall 32 are examples of "wall portions".

[0055] The height of the outer peripheral wall 31 and the inner peripheral wall 32 (the protruding height from the upper surface 21a of the substrate 21) is desirably the same as or higher than the height of the index 23. The height of the outer peripheral wall 31 and the inner peripheral wall 32 may be, for example, 0.03 mm or more (for example, 0.1 mm or more). By setting the height of the outer peripheral wall 31 and the inner peripheral wall 32 within this range, it becomes easier to prevent the filled resin from spilling out of the substrate 21 in the step of forming the resin layer 22.

[0056] The resin layer 22 (height adjustment layer, adjustment layer) is formed in an area of ​​the upper surface 21a where the index 23 is not formed. The resin layer 22 is formed between the outer peripheral wall 31 and the inner peripheral wall 32.

[0057] The resin layer 22 has an upper surface 22a (second main surface). The upper surface 22a is located higher than the upper surface 21a of the substrate 21. The upper surface 22a is, for example, parallel to the XY plane. It is desirable that the resin layer 22 is formed on the entire region of the upper surface 21a of the substrate 21 where the index 23 is not formed. It is sufficient that the resin layer 22 is formed on at least a part of the region of the upper surface 21a where the index 23 is not formed.

[0058] The upper surface 22a of the resin layer 22 is desirably at the same height as the end surface 23a of the index 23 or is located lower than the end surface 23a. The height position of the upper surface 22a of the resin layer 22 is desirably equivalent to the height position of the end surface 23a. "Equivalent" means, for example, that the height difference between the upper surface 22a and the end surface 23a is 0 mm or more and 0.05 mm or less. The height difference between the upper surface 22a and the end surface 23a is preferably 0 mm or more and 0.03 mm or less (for example, 0 mm or more and 0.01 mm or less).

[0059] In this embodiment, the upper surface 22a of the resin layer 22 is at the same height as the end surface 23a of the index 23. Therefore, the upper surface 22a is flush with the end surface 23a.

[0060] The resin layer 22 desirably has optical transparency in the thickness direction. "Having optical transparency" means, for example, that the optical transmittance (visible light transmittance) in the range of visible light wavelengths (380 nm to 780 nm) is 50% or more (preferably 70% or more, and more preferably 80% or more). The visible light transmittance is calculated as the average value of the transmittance in the entire wavelength range of visible light. The optical transmittance can be measured, for example, in accordance with "Plastics - Determination of total light transmittance and total light reflectance" as defined in JIS K 7375:2008. The resin layer 22 has optical transparency in the thickness direction, and therefore has transparency.

[0061] The resin layer 22 is formed of, for example, a resin. The resin layer 22 is formed of, for example, a thermoplastic resin such as a polyolefin resin (such as polypropylene), an ABS resin, an acrylic resin, etc. The resin layer 22 may be formed of a thermosetting resin such as a melamine resin, a phenol resin, etc.

[0062] In the dial 3, an outer peripheral wall 31 and an inner peripheral wall 32 are formed on the substrate 21, but it is sufficient for the dial to have at least one of the outer peripheral wall and the inner peripheral wall. For example, of the outer peripheral wall and the inner peripheral wall, only the outer peripheral wall may be formed, or only the inner peripheral wall may be formed.

[0063] [Manufacturing method for watch dials] Fig. 6 is an explanatory diagram of a method for manufacturing the dial 3. An example of a method for manufacturing the dial 3 will be described with reference to Fig. 6.

[0064] (1st step: resin layer formation step) As shown in FIG. 6, the resin layer 22 can be formed as follows. Uncured resin is applied to the area of ​​the upper surface 21a where the index 23 is not formed. The resin is filled into the space defined by the substrate 21, the outer peripheral wall 31, and the inner peripheral wall 32. The resin is cured. For example, when the resin is a thermoplastic resin, the resin is cured by cooling. The surface of the cured resin may be polished. Polishing gives the resin layer 22 a glossy finish.

[0065] (Second process: stencil placement process) The printed layer 24 can be formed by a printing method, such as screen printing. A perforated mask 40 for forming the printing layer 24 is prepared. The perforated mask 40 is in the form of a plate. The perforated mask 40 has holes 41 formed therein, each having a shape corresponding to the shape of the printing layer 24.

[0066] A mask 40 is placed on the substrate 21 on which the underlayer 25 (not shown in FIG. 6) is formed. The mask 40 is positioned so that the holes 41 overlap the indexes 23.

[0067] (3rd process: printing process) The material 43 of the printing layer 24 is placed on the stencil 40, and the squeegee 42 is moved while being pressed against the upper surface of the stencil 40. The material 43 of the printing layer 24 moves over the upper surface of the stencil 40 by the squeegee 42. A part of the material 43 of the printing layer 24 is pushed downward through the holes 41 and applied to the end surface 23a of the index 23. The applied material 43 becomes the printing layer 24. In this way, the dial 3 on which the printing layer 24 is formed is obtained (see FIG. 3). The stencil 40 may be pressed by the squeegee 42 and come into contact with the outer peripheral wall 31, the inner peripheral wall 32, and the resin layer 22.

[0068] [Effects of the timepiece dial according to the embodiment]

[0069] The dial 3 has an outer peripheral wall 31 and an inner peripheral wall 32 that protrude from the upper surface 21a. Therefore, in the process of forming the resin layer 22, it is possible to prevent the filled resin from spilling out of the substrate 21. Therefore, the shape of the resin layer 22 is less likely to be distorted due to the resin spilling out. This makes it possible to increase the accuracy of forming the resin layer 22. As a result, it is possible to improve the quality of the appearance of the dial 3.

[0070] The resin is filled into the space surrounded by the outer peripheral wall 31 and the inner peripheral wall 32. Therefore, compared to a case where there is no outer peripheral wall 31 or inner peripheral wall 32, the resin is applied to a limited area on the substrate 21. Since the area where the resin is applied can be narrowed, warping due to resin shrinkage during the curing process is less likely to occur.

[0071] Since the dial 3 has an outer peripheral wall 31 and an inner peripheral wall 32, even if the squeegee 42 is pressed against the stencil 40 in the printing process, the stencil 40 can be prevented from bending downward. Therefore, the holes 41 are less likely to be displaced or deformed due to bending deformation of the stencil 40. This makes it less likely that the printed layer 24 will be displaced or distorted in shape. This makes it possible to increase the accuracy of forming the printed layer 24. This makes it possible to improve the quality of the appearance of the dial 3.

[0072] As described above, in the dial 3, the precision with which the resin layer 22 is formed can be increased, making it less likely for the resin layer 22 to interfere with other parts in the timepiece 1 (see FIG. 1). This makes it possible to avoid a drop in production efficiency caused by irregularities in the shape of the resin layer 22.

[0073] Since the dial 3 includes a resin layer 22 having an upper surface 22a, even if the squeegee 42 is pressed against the screen 40 in the printing process, the screen 40 can be prevented from bending downward. Therefore, the holes 41 are less likely to be displaced or deformed due to bending deformation of the screen 40. This makes it less likely that the printed layer 24 will be displaced or distorted in shape. This makes it possible to increase the accuracy of forming the printed layer 24. This makes it possible to improve the quality of the appearance of the dial 3. The resin layer 22 also has the advantage of protecting the substrate 21.

[0074] In the dial 3, if at least one of the outer peripheral wall 31 and the inner peripheral wall 32 is formed, it is possible to prevent the resin from spilling out of the substrate 21 in the process of forming the resin layer 22. For example, the outer peripheral wall 31 can prevent the resin from spilling outward from the substrate 21. The inner peripheral wall 32 can prevent the resin from spilling inward from the substrate 21. This improves the accuracy of forming the resin layer 22.

[0075] In the dial 3, it is preferable that the height position of the upper surface 22a of the resin layer 22 is the same as the height position of the end surface 23a of the index 23. With this configuration, downward bending of the perforated plate 40 can be suppressed during the manufacture of the dial 3. Therefore, the formation accuracy of the printing layer 24 can be improved.

[0076] In the dial 3, it is preferable that the periphery 24a of the printed layer 24 is located inside the periphery 23b of the end face 23a in a plan view. With this configuration, even if the formation position of the printed layer 24 is shifted, the printed layer 24 will be contained within the area of ​​the end face 23a of the index 23 as long as the shift is not large. Therefore, the position shift of the printed layer 24 can be made inconspicuous.

[0077] The dial 3 preferably has a printed layer 24 and an undercoat layer 25. It is preferable that the periphery 24a of the printed layer 24 is located inside the periphery 25a of the undercoat layer 25 in a plan view. With this configuration, even if the formation position of the printed layer 24 is shifted, the printed layer 24 will be contained within the area of ​​the undercoat layer 25 as long as the shift is not large. Therefore, the positional shift of the printed layer 24 is difficult to visually recognize. Therefore, the positional shift of the printed layer 24 can be made less noticeable.

[0078] It is preferable that the resin layer 22 is optically transparent. This configuration can improve the aesthetic appearance of the dial 3. For example, the resin layer 22 can give a sense of depth to the dial 3. When a surface decoration is formed on the upper surface 21a of the substrate 21, a three-dimensional, deep visual effect can be imparted to the surface decoration.

[0079] Because the timepiece 1 has a dial 3 with the above-described configuration, the precision with which the printed layer 24 is formed can be improved when manufacturing the dial 3. This makes it possible to improve the quality of the appearance of the dial 3.

[0080] [Clock dial] (Second embodiment) 7 is a cross-sectional view of a dial 103 according to the second embodiment. Configurations common to the other embodiments are given the same reference numerals and descriptions thereof will be omitted.

[0081] As shown in Fig. 7, in the dial 103, the multiple indexes 23 include two types of indexes 23A and 23B with different heights. The index 23A is formed lower than the index 23B. The height of the resin layer 122 is determined according to the lower index 23A. The height of the upper surface 122a of the resin layer 122 may be equal to the height of the index 23A. The upper surface 122a of the resin layer 122 is lower than the end surface of the index 23B.

[0082] The dial 103 has two types of indexes 23A and 23B with different heights, which is excellent in terms of design. The height of the resin layer 122 is determined according to the lower index 23A, so that the upper surfaces (end surfaces) of all the indexes 23 can be exposed.

[0083] [Clock dial] (third embodiment) 8 is a cross-sectional view of a dial 203 according to the third embodiment. Configurations common to the other embodiments are given the same reference numerals and descriptions thereof will be omitted.

[0084] As shown in FIG. 8, in the dial 203, the resin layer 222 has a multi-layer structure having a plurality of layers in the thickness direction (Z direction). The resin layer 222 has, for example, a first layer 22A and a second layer 22B. The second layer 22B is formed on the first layer 22A. The first layer 22A and the second layer 22B have, for example, different optical properties (refractive index, color, light transmittance, etc.). The first layer 22A and the second layer 22B have, for example, different constituent materials. The number of layers constituting the resin layer is not limited to two and may be any number equal to or greater than two.

[0085] In forming the resin layer 222, for example, a resin is applied onto the first layer 22A obtained by applying a resin to form the second layer 22B. The resin layer 222 may be formed, for example, by applying additional resin onto a resin layer (first layer 22A) that has shrunk and become thinner when the resin is cured, to form the second layer 22B.

[0086] In the dial 203, the resin layer 222 has multiple layers, which increases the degree of freedom in designing the appearance. For example, a three-dimensional visual effect with depth can be obtained by reflection at the boundaries between multiple layers. This improves the aesthetic appearance of the dial 203.

[0087] When the second layer 22B is formed by applying additional resin onto a resin layer (first layer 22A) that has shrunk and become thinner when the resin is cured, the surface of the resin layer 222 can be easily exposed.

[0088] [Clock dial] (fourth embodiment) 9 is a cross-sectional view of a dial 303 according to the fourth embodiment. Configurations common to the other embodiments are given the same reference numerals and descriptions thereof will be omitted. As shown in FIG. 9, in the dial 303, the resin layer 322 is divided into a plurality of regions in a plan view. The resin layer 322 has, for example, a first region 22C and a second region 22D. The first region 22C is an annular region whose outer periphery reaches the outer periphery wall 31. The second region 22D is an annular region formed on the inner periphery side of the first region 22C. The inner periphery of the second region 22D reaches the inner periphery wall 32. The first region 22C and the second region 22D have, for example, different optical properties (color, refractive index, light transmittance, etc.). The number of regions constituting the resin layer is not limited to two, and may be any number equal to or greater than two.

[0089] The dial 303 can be expressed in a variety of ways because the resin layer 322 has a plurality of regions, and therefore the aesthetic appearance of the dial 303 can be improved.

[0090] [Clock dial] (Fifth embodiment) Fig. 10 is a plan view of a dial 403 according to the fifth embodiment, and Fig. 11 is a perspective view of the dial 403. Configurations common to the other embodiments are given the same reference numerals and description thereof will be omitted. As shown in FIG. 10 and FIG. 11, in the dial 403, the resin layer 422 is divided into a plurality of regions in a plan view. The resin layer 422 has, for example, a first region 22E and a second region 22F. The first region 22E and the second region 22F are divided by a boundary 426. The boundary 426 is formed by connecting a semicircular first curved portion 426a and a semicircular second curved portion 426b. The first curved portion 426a and the second curved portion 426b are convex in opposite directions, and the boundary 426 is S-shaped as a whole. The first region 22E and the second region 22F are different from each other in optical properties (color, refractive index, light transmittance, etc.), for example. The number of regions constituting the resin layer is not limited to two, and may be any number equal to or greater than two.

[0091] The resin layer 422 has design properties. "Having design properties" means, for example, that the resin layer is partitioned into a plurality of regions by boundaries, and is capable of displaying a recognizable shape. The resin layer 422 is partitioned into two regions 22E, 22F by an S-shaped boundary 426. The outer peripheries of the first region 22E and the second region 22F are semicircular. Therefore, the first region 22E and the second region 22F can be recognized as having a shape with an S-shaped inner periphery and a semicircular outer periphery. Therefore, the resin layer 422 has design properties.

[0092] Since the resin layer 422 of the dial 403 has a design property, the aesthetic appearance can be improved.

[0093] The present invention is not limited to the above-described embodiment explained with reference to the drawings, and various modifications are possible within the technical scope of the present invention. For example, in the dial 3 of the embodiment, the printed layer 24 is indirectly formed on the index 23 via the base layer 25, but the printed layer 24 may be directly formed on the end surface 23a of the index 23. In other words, the printed layer 24 can be formed directly or indirectly on the end surface 23a of the index 23.

[0094] In the dial 3, the resin layer 22 may be fixed to the substrate 21 or may not be fixed to the substrate 21. The resin layer 22 may be detachable from the substrate 21. It is desirable for the resin layer 22 to be light-transmitting, but it does not have to be light-transmitting. [Explanation of symbols]
