Description

[Technical field]

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

[0002] Patent Document 1 discloses a timepiece part, such as a dial, which has a color-tuning layer made of multiple oxide films laminated on a base material with metallic luster, thereby achieving an appearance and texture equivalent to that of a precious metal material while at the same time reducing costs compared to when a precious metal material is used. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2023-4622 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, when brass or the like is used as the base material for the dial, there is a possibility that the base material may rust. For this reason, it is conceivable to form a protective film of nickel or the like on the surface of the base material by wet plating, and then laminate multiple oxide films that function as toning layers on the surface of this protective film by vacuum deposition. However, as a result of research by the present inventors, it was found that when a protective film is formed by wet plating and then a toning layer is formed by vacuum deposition, the surface of the protective film is inactivated, so that the first oxide film of the toning layer is simply placed on the surface of the protective film, and the adhesion between them is low, and peeling may occur if a tool or the like comes into contact with the dial surface during assembly or maintenance of the watch, etc. For this reason, there is a demand for a watch component that can improve the adhesion between the protective film and the toning layer and is less likely to peel off when the protective film and the toning layer are laminated on the surface of the base material, and a watch using this watch component. [Means for solving the problem]

[0005] The watch component disclosed herein comprises a base material, a protective film formed on the surface of the base material by wet plating, and a decorative film formed on the surface of the protective film by dry plating, the decorative film being a laminated film in which a plurality of layers including a first layer in contact with the protective film are laminated, and the main material constituting the first layer is the same as the main material constituting the protective film.

[0006] The timepiece of the present disclosure is characterized by including the timepiece component described above. [Brief description of the drawings]

[0008] A timepiece 1 according to an embodiment of the present disclosure will now be described with reference to the drawings. 1 is a front view showing a timepiece 1 having a dial 10 which is a timepiece part of the first embodiment. The timepiece 1 is a wristwatch worn on the user's wrist and has a metal exterior case 2, with the dial 10 disposed on the inner circumference of the exterior case 2. Of the two openings in the exterior case 2, the opening on the front side is covered with a cover crystal, and the opening on the back side is covered with a back cover. The timepiece 1 also has a movement (not shown) housed in the exterior case 2, a second hand 3, a minute hand 4, and an hour hand 5 which are hands that indicate time information, a crown 7, an A button 8, and a B button 9. The dial 10 is provided with indexes 12. In this embodiment, the indexes 12 are bar indexes, but Roman numerals or Arabic numerals may also be used, and the type of index is not limited to bar indexes. In the following description, the front surface of each component means the surface facing the cover glass, and the back surface of each component means the surface facing the back cover.

[0009] [Dial] FIG. 2 is a schematic cross-sectional view of a dial 10 which is a timepiece component, and FIG. 3 is a diagram showing the material, film formation method, and film thickness of each film of the dial 10. The dial 10 has a base material 20, a protective film 21 formed on the surface of the base material 20, a decorative film 30 consisting of a plurality of layers laminated on the surface of the protective film 21, and a top coat film 40 formed on the surface of the decorative film 30. The substrate 20 is a metal substrate that serves as the base material for the dial 10. The substrate 20 is, for example, a brass plate with a thickness of about 400,000 nm (about 0.4 mm). The material of the substrate 20 is not limited to brass, and is preferably a metal that is less noble than a precious metal, such as nickel silver, Al, Ti, V, Cr, Fe, Co, Ni, Cu, Zn, Zr, Nb, Mo, In, Sn, Hf, Ta, W, Bi, Mg, or an alloy containing at least one of these. It is not prohibited to include a small amount of a precious metal.

[0010] The protective film 21 is a Ni plating layer formed on the surface of the base material 20 by wet plating such as electrolytic plating. That is, the protective film 21 is a film whose main material is Ni, and for example, the content of Ni as the main component is 99% or more, and the contents of other components are about 1%. Furthermore, the protective film 21 may contain less than 99% of Ni as the main component, so long as it can protect the brass base material 20 and prevent rust from occurring on the base material 20. Furthermore, since the protective film 21 is formed by wet plating, it is suitable for mass production. The thickness of the protective film 21 is, for example, about 300 nm. The main material of the protective film 21 is not limited to Ni, and may be any material that can achieve the functions required of the protective film 21, such as anti-rust function, and may be a material that can be wet-plated, such as Au, Ag, or Rh. In particular, Ni has the advantage of being less expensive than Au, Ag, or Rh.

[0011] The decorative film 30 is provided to adjust the appearance and texture of the dial 10, and in this embodiment, is composed of seven layers laminated in order from the protective film 21 side. That is, the decorative film 30 is composed of a first layer 31, a second layer 32, a third layer 33, a fourth layer 34, a fifth layer 35, a sixth layer 36, and a seventh layer 37, which are laminated in order from the surface of the protective film 21. In this embodiment, the film means a portion formed to realize a predetermined function. For example, the protective film 21 and the topcoat film 40 are single-layer films formed from one type of material. On the other hand, the decorative film 30 is a laminated film in which multiple layers of different materials are laminated to decorate the dial 10, specifically to adjust the color and gloss of the dial 10. The protective film 21 has the function of protecting the base material 20, but may also have other functions, for example, a function of contributing to the decoration of the dial 10 together with the decorative film 30. The decorative film 30 as a whole only needs to have the function of decorating the dial 10, and some of the first layer 31 to the seventh layer 37 may not directly contribute to the decoration.

[0012] The first layer 31 to the seventh layer 37 constituting the decorative film 30 are formed by dry plating such as vacuum deposition, sputtering, ion plating, etc. The specific method of forming the film by dry plating may be set according to the material and characteristics of each layer. The first layer 31 is formed on the surface of the protective film 21 by dry plating such as vacuum deposition. The main material constituting the first layer 31 is the same material as the main material constituting the protective film 21, that is, Ni. The Ni of the wet plating of the protective film 21 and the Ni of the dry plating of the first layer 31 are the same material, and a metallic bond is generated, so that the adhesion can be improved compared to the case where an oxide film is formed on the surface of the protective film 21. That is, although the first layer 31 is a layer constituting the decorative film 30, it is provided mainly to increase the adhesion with the protective film 21. Therefore, the first layer 31 may not contribute to decoration or may only contribute little to decoration. The film thickness of the first layer 31 is, for example, about 100 nm. The first layer 31 is, for example, a layer in which the content of Ni, which is the main component, is 99% or more and the content of other components is about 1%. In addition, as long as the first layer 31 can ensure the necessary performance through adhesion to the protective film 21, the content of Ni, which is the main component, may be less than 99%.

[0013] The second layer 32 is formed on the surface of the first layer 31 by dry plating such as vacuum deposition. The main material constituting the second layer 32 is Cr. Cr has high affinity with Ni, good adhesion, and a high light reflectance of about 60% or more, so that the third layer 33 to the seventh layer 37 can increase the design freedom of the color and gloss of the dial 10. That is, when the dial 10 is viewed from the front, the reflectance of the second layer 32 is high, so that the influence of the base material 20, the protective film 21, and the first layer 31 on the color of the dial 10 can be reduced, and the color and gloss of the dial 10 can be freely designed by the configuration of the third layer 33 to the seventh layer 37. Therefore, the second layer 32 has a function of increasing adhesion with the first layer 31 and a function of contributing to decoration. The film thickness of the second layer 32 is, for example, 68.4 nm. The second layer 32 is, for example, a layer in which the content of Cr, which is the main component, is 99% or more and the content of other components is about 1%. Furthermore, the second layer 32 may have a Cr content of less than 99% as a main component, so long as necessary performance, such as adhesion to the first layer 31 and light reflectance, can be ensured.

[0014] The third layer 33 to the seventh layer 37 are composed of any one of a metal material, an oxide, and a fluoride, and the material and film thickness of these layers are set according to the color of the dial 10. In this embodiment, the third layer 33 to the seventh layer 37 are mainly made of the material shown in Fig. 3 and are formed to the film thickness shown in Fig. 3. The third layer 33 is formed by dry plating such as vacuum deposition on the surface of the second layer 32. The third layer 33 is made of Al2O3 and has a thickness of, for example, 207.6 nm. The fourth layer 34 is formed by dry plating such as vacuum deposition on the surface of the third layer 33. The fourth layer 34 is made of Cr and has a thickness of, for example, 7.3 nm. The fifth layer 35 is formed by dry plating such as vacuum deposition on the surface of the fourth layer 34. The fifth layer 35 is made of Al2O3, and has a thickness of, for example, 111.4 nm. The sixth layer 36 is formed by dry plating such as vacuum deposition on the surface of the fifth layer 35. The sixth layer 36 is made of Nb2O5, and has a thickness of, for example, 76.8 nm. The seventh layer 37 is formed by dry plating such as vacuum deposition on the surface of the sixth layer 36. The seventh layer 37 is made of SiO2 and has a thickness of, for example, 116.4 nm. These third layer 33 to seventh layer 37 are layers that contribute to decoration, but also have sufficient adhesion to maintain the laminated state without peeling between the layers.

[0015] The top coat film 40 is formed by applying acrylic resin with a spray gun or the like to the surface of the decorative film 30, specifically, the surface of the seventh layer 37. The top coat film 40 is provided for the purpose of providing gloss and adjusting color in addition to protecting the decorative film 30. The film thickness of the top coat film 40 is about 50000 nm = about 0.05 mm.

[0016] According to the dial 10 having the above-mentioned configuration, in particular by configuring the decorative film 30 with the first layer 31 to the seventh layer 37 having the material and thickness shown in FIG. 3, the color of the dial 10 can be made red, specifically, the brightness L * =37, saturation C * =53 and hue angle h=13.

[0017] [Peel test results] FIG. 4 shows the results of a peel test conducted to test the adhesion between the dial 10 of the first embodiment, which is an example, and a dial of a comparative example. The dial of the comparative example is different from the dial 10 of the first embodiment in that the first layer 31 of the decorative film 30 is made of SiO2, but the other configurations are the same. Also, the pattern "surface preparation" in Fig. 4 means that the surface of the base material 20 is polished to make it flat. The peeling test is carried out according to the following procedure. Six samples are prepared for each of the examples and comparative examples, and linear cuts are made in two intersecting directions with a cutter on the surface of each sample to divide it into rectangular regions of about 1 mm square. Next, adhesive tape is attached to the surface of each sample, and the adhesive tape is peeled off to test whether the decorative film 30 peels off from the substrate 20. As shown in FIG. 4, in the example, in all of the six samples, peeling did not occur in the rectangular area defined by the cuts, and it was confirmed that the decorative film 30 had high adhesion and was a good product. On the other hand, in the comparative example, peeling occurred in the rectangular area defined by the cut in four of the six samples. When the defective products in which peeling occurred were inspected, it was confirmed that peeling occurred between the Ni-plated protective film 21 and the first layer 31 of SiO2.

[0018] As described above, the dial 10 of the first embodiment and the timepiece 1 equipped with this dial 10 can achieve the following effects. In other words, although the protective film 21 formed on the surface of the base material 20 and the first layer 31 of the decorative film 30 formed on the surface of the protective film 21 are formed using different methods, the main material is the same, Ni, and therefore adhesion can be improved by metallic bonding, and peeling of the decorative film 30 from the protective film 21 can be prevented. The protective film 21 is formed by wet plating of Ni, and therefore is suitable for mass production and can be formed at low cost.

[0019] [Second embodiment] Next, a second embodiment will be described with reference to Fig. 5. The dial 10 of the second embodiment differs from the dial 10 of the first embodiment only in the film thickness of the second layer 32 to the seventh layer 37 of the decorative film 30. The other configurations are the same as those of the first embodiment, so the same reference numerals as those of the first embodiment will be used in the description. The base material 20, protective film 21, first layer 31 of the decorative film 30, and top coat film 40 of the dial 10 of the second embodiment are the same in material, film formation method, and film thickness as those of the first embodiment, so description thereof will be omitted. The second layer 32 to the seventh layer 37 of the decorative film 30 are made of the same material and formed by the same method as in the first embodiment, but only the thickness is different. That is, the second layer 32 made of Cr has a thickness of 71.15 nm. The third layer 33 made of Al2O3 has a thickness of 88.77 nm. The fourth layer 34 made of Cr has a thickness of 12.73 nm. The fifth layer 35 made of Al2O3 has a thickness of 117.75 nm. The sixth layer 36 made of Nb2O5 has a thickness of 93.71 nm. The seventh layer 37 made of SiO2 has a thickness of 146.08 nm.

[0020] According to the dial 10 of the second embodiment configured as above, in particular by configuring the decorative film 30 with the first layer 31 to the seventh layer 37 having the material and thickness shown in FIG. 5, the color of the dial 10 is purple, specifically, the lightness L * =31, saturation C * =38 and hue angle h=-45.

[0021] The dial 10 of the second embodiment differs from the dial 10 of the first embodiment only in the film thicknesses of the second layer 32 to the seventh layer 37, and therefore can achieve the same effects as the first embodiment. That is, since the protective film 21 and the first layer 31 are made of the same Ni, adhesion can be improved by metallic bonding, and peeling of the decorative film 30 can be prevented.

[0022] [Third embodiment] Next, a dial 10C of a third embodiment will be described with reference to FIGS. The dial 10C is configured to include a base material 20, a protective film 21, a decorative film 30C, and a top coat film 40. The base material 20, the protective film 21, and the top coat film 40 are made of the same material, are formed by the same method, and have the same film thickness as the dial 10 of the first and second embodiments, so they are denoted by the same reference numerals and will not be described.

[0023] The decorative film 30C is formed by laminating eight layers, from a first layer 31 to an eighth layer . The first layer 31 is made of Ni formed by dry plating in the same manner as in the first and second embodiments, and has a thickness of 100 nm. The second layer 32 is made of Cr formed by dry plating and has a thickness of 68.3 nm. The third layer 33 is made of Al2O3 formed by dry plating and has a thickness of 0.23 nm. The fourth layer 34 is made of Cr formed by dry plating and has a thickness of 8.39 nm. The fifth layer 35 is made of Al2O3 formed by dry plating and has a thickness of 94.88 nm. The sixth layer 36 is made of TiO2 formed by dry plating and has a thickness of 61.97 nm. The seventh layer 37 is made of Al2O3 formed by dry plating and has a thickness of 168.78 nm. The eighth layer 38 is made of SiO2 formed by dry plating and has a thickness of 95.32 nm.

[0024] According to the dial 10C of the third embodiment configured as above, in particular by configuring the decorative film 30 with the first layer 31 to the eighth layer 38 having the material and thickness shown in FIG. 7, the color of the dial 10C is green, specifically, the lightness L * =88, saturation C * =45 and hue angle h=102.

[0025] The dial 10C of the third embodiment differs from the dial 10 of the first embodiment in the materials and film thicknesses of the second layer 32 to the eighth layer 38 of the decorative film 30C. However, the protective film 21 and the first layer 31 are made of Ni, as in the first embodiment, so that, as in the first embodiment, adhesion can be improved by metal bonding and peeling of the decorative film 30 can be prevented.

[0026] [Variations] The main material constituting the protective film 21 and the first layer 31 is not limited to Ni, and may be, for example, Au, Ag, Rh, etc. In other words, the main material constituting the protective film 21 and the first layer 31 is the same material, and therefore any material may be used as long as it can be formed on the base material 20 by wet plating and can be formed on the surface of the protective film 21 by dry plating and further has a function of protecting the base material 20, such as rust prevention. The main material constituting the second layer 32 is not limited to Cr, and may be any material that has high adhesion to the first layer 31 and a reflectance of a predetermined value or more, such as Al, Au, Ag, etc. In other words, the second layer 32 may be any material that has a visible light reflectance of 50% or more, preferably 60% or more, reduces the visible light that transmits through the second layer 32, and reduces the influence of the first layer 31, protective film 21, and base material 20 arranged on the back side of the second layer 32 on the color and gloss of the watch components. The number, material, and thickness of each layer after the third layer 33 are not limited to the configurations of the above-mentioned embodiments, and may be set according to the design of the color and luster of the watch component. For example, in the decorative film 30, 30C, when a metal material layer is provided for each layer after the third layer 33 other than the first layer 31 and the second layer 32, the material is not limited to Cr, and may be Al, Ti, V, Fe, Co, Ni, Cu, Zn, Zr, Nb, Mo, In, Sn, Hf, Ta, W, Bi, Mg, etc. Also, when an oxide or fluoride layer is provided for each layer after the third layer 33, for example, Ta2O5, SiO2, TiO2, Al2O3, ZrO2, Nb2O5, HfO2, Na5Al3F 14 , Na3AlF6, AlF3, MgF2, CaF2, BaF2, YF3, LaF3, CeF3, NdF3, etc. can be selected depending on the color.

[0027] Although the substrate 20 has been described as being made of a metal material, the material is not limited to this, and a substrate made of a material other than a metal, such as a synthetic resin, may also be used. In the above-described embodiments, the material of the top coat film 40 provided on the surface of the decorative film 30, 30C is not limited to acrylic resin. Also, the watch component may not be provided with the top coat film 40. Furthermore, the top coat film 40 may be provided only for the purpose of protecting the decorative film 30.

[0028] The timepiece parts are not limited to the dials 10 and 10C, and may be applied to various timepiece parts that are visible from the outside of a timepiece. For example, in a skeleton model timepiece, the present invention may be applied to various timepiece parts that are visible from the outside of the movement, such as an oscillating weight, a wheel train, an escape wheel, an anchor, a wheel train bridge, and an oscillating weight bridge. Furthermore, the timepiece parts may be the outer case 2, the crown 7, the back cover, the band, etc., which are made of metal materials.

[0029] [Summary of this disclosure] The watch component disclosed herein has a base material, a protective film formed on the surface of the base material by wet plating, and a decorative film formed on the surface of the protective film by dry plating, and is characterized in that the decorative film is a laminated film in which a plurality of layers including a first layer in contact with the protective film are laminated, and the main material constituting the first layer is the same as the main material constituting the protective film. According to the watch component disclosed herein, the protective film formed on the surface of the base material by wet plating and the first layer of the decorative film formed on the surface of the protective film by dry plating are mainly made of the same material, thereby increasing the affinity between the protective film and the first layer, improving the adhesion between them, and preventing peeling of the decorative film. In addition, since the protective film is formed by wet plating, it is suitable for mass production and costs can be reduced. Furthermore, since the decorative film is a laminated film in which multiple layers are laminated, and each layer is formed by dry plating, the thickness of each layer can be set with high precision, and the color of the watch component, which is affected by the film thickness, can be set with high precision to the desired color.

[0030] In the watch component of the present disclosure, it is preferable that the main material constituting the protective film and the first layer is Ni. According to the watch component of the present disclosure, the protective layer is formed by depositing Ni, the main material, by wet plating, so that a protective film having an anti-rust effect can be formed at low cost. Furthermore, since the first layer of the decorative film is formed by depositing Ni by dry plating, the Ni of the protective film and the Ni of the first layer are metallically bonded, improving adhesion.

[0031] In the watch component of the present disclosure, it is preferable that the decorative film has a second layer in contact with the first layer, and a third layer and subsequent layers laminated on the surface side of the second layer, and that the main material constituting the second layer is a material that has high adhesion to the first layer and a reflectance of a predetermined value or higher. According to the watch component of the present disclosure, the second layer of the decorative film is mainly made of a material that has high adhesion to the first layer, so peeling between the first and second layers of the decorative film can be prevented. In addition, the main material constituting the second layer of the decorative film is made of a material with a reflectance of a predetermined value or more, so that when the watch component is viewed from the front side, the base material, protective film, and first layer of the decorative film, which are located on the back side of the second layer, can be prevented from affecting the color of the watch component. Therefore, the color of the watch component can be easily set by the material and film thickness of the third and subsequent layers of the decorative film.

[0032] In the timepiece component of the present disclosure, the main material constituting the second layer is preferably Cr. According to the watch component of the present disclosure, the second layer of the decorative film is made of Cr, and by making the first layer of the decorative film out of a material that has a high affinity with Cr, such as Ni, the adhesion between the first and second layers can be increased and peeling between the first and second layers of the decorative film can be prevented. In addition, because Cr has a high reflectivity, it is possible to prevent the base material, protective film, and first layer of the decorative film, which are located behind the second layer, from affecting the color of the watch component when the watch component is viewed from the front side. This makes it easy to set the color of the watch component by changing the material and film thickness of the third and subsequent layers of the decorative film.

[0033] In the watch component of the present disclosure, the third and subsequent layers preferably have a layer made of a metallic material and a layer made of an oxide or fluoride. According to the watch component of the present disclosure, the third layer and subsequent layers of the decorative film are provided with a layer of metal material and a layer formed of an oxide or fluoride, so that the color of the watch component can be easily set by the material and film thickness of the third layer and subsequent layers.

[0034] In the timepiece component of the present disclosure, the layer formed from the metal material is preferably made of a material containing at least one selected from the group consisting of Cr, Au, Ag, and Rh. According to the watch component of the present disclosure, the third and subsequent layers in the decorative film, which affect the color of the watch component, have layers formed of a metallic material containing at least one selected from the group consisting of Cr, Au, Ag, and Rh, so that the watch component can have a certain metallic luster.

[0035] In the watch component of the present disclosure, the layer formed of the oxide or fluoride is Ta2O5, SiO2, TiO2, Al2O3, ZrO2, Nb2O5, HfO2, Na5Al3F 14 It is preferable that the cathode material be made of a material containing at least one selected from the group consisting of Na3AlF6, AlF3, MgF2, CaF2, BaF2, YF3, LaF3, CeF3, and NdF3. According to the timepiece component of the present disclosure, the color displayed on the timepiece component can be appropriately set by adjusting the material and film thickness of the layer configuration of the decorative film.

[0036] In the watch component of the present disclosure, it is preferable to have a top coat film formed on the surface of the decorative film. According to the watch component of the present disclosure, the decorative film can be protected by the top coat film, and the gloss and color of the watch component can be set.

[0037] In the timepiece components of the present disclosure, the timepiece components are preferably dial or movement components. According to the timepiece components of the present disclosure, a predetermined color can be set for the dial or movement components such as the oscillating weight.

[0038] The timepiece of the present disclosure is characterized by including the timepiece component described above. According to the timepiece of the present disclosure, a timepiece can be provided that is equipped with timepiece components that display a predetermined color. [Explanation of symbols]
