Aluminum also contains aluminum coated with an aluminum oxide film on the surface by anodizing.
    This structure enables a wristwatch band that is not easily scratched to be made by manufacturing integrally molded band link units from the above various materials. In particular, when manufactured from a ceramic, manufacture is easy, and at the same time the integrally formed band link units can be provided with various colors as desired, whereby the texture quality of the wristwatch band can be improved and there are more decoration options.

    By an eighth feature of the present embodiment, the inner band link of one of the two integrally formed band link units and the outer band link of the other integrally formed band link unit are machined at least on the surfaces in the same way, while the inner band link of the other integrally formed band link unit and the outer band Belt link of the one integrally formed belt link unit are machined at least on the surfaces other than the surface of the inner belt link of the one integrally formed belt link unit.
    The above structures can enable new decoration options for the external appearance of the wristwatch.
    The wrist watch band and the wrist watch according to the embodiment of the present invention are explained in more detail below with reference to FIGS. 1 to 8. On the wristwatch band 1 of the present embodiment, a band link block 2, as shown in FIG. 1, consists of at least two integrally formed band link units 3, 4 and two cylindrical webs 5a, 5b which support and fasten these integrally formed band link units 3, 4 in lateral directions.
    As can be seen from FIGS. 1 to 3, an inner band link 3a, 4a and an outer band link 3b, 4b are formed in one piece with each other on the two integrally formed band link units 3, 4 such that the two integrally molded band link units 3, 4 are formed in a substantially elliptical shape. A non-continuous blind bore 3b1, 4b1 is machined into each of the two outer hinge links 3b, 4b. A through hole 3a1, 4a1 is machined into each of the two inner hinge links 3a, 4a.
    In this way, the inner band member 3a, 4a and the outer band member 3b, 4b to the integrally formed band link unit 3, 4 are integrally formed with each other, so that it is no longer necessary that between the inner band member 3a, 4a and the outer band member 3b, 4b a fastening part and a fastening point are provided. Therefore, the number of components and the fastening points can be reduced and the risk of deterioration due to aging is reduced. At the same time, the work processes for fastening the inner band link 3a, 4a to the outer band link 3b, 4b are reduced, thereby enabling the mass productivity to be improved and the cost of the wrist watch band 1 to be reduced.
    As can be seen from Figure 2, a recess-like groove 3a2 and a projection-like locking bar 3a3 are formed by a one-piece molding process in the inner band link 3a of an integrally formed band link unit 3 in the bottom on the side facing away from the outer band link 3b. In the inner band link 4a of the other integrally molded band link unit 4, a recess-like groove 4a2 and a projection-like locking bar 4a3 are formed by an integral molding process such that the recess-like groove 4a2 and the projection-like locking bar 4a3 are continued from the side face remote from the outer band member 4b.
    In the locking bar 3a3, part of the through hole 3a1 is formed by a one-piece molding process. In the sides of the groove 3a2, a part of the through hole 3a1 is formed by the integral molding method. In the locking bar 4a3, a part of the through hole 4a1 is formed by the one-piece molding method. In the sides of the groove 4a2, part or the whole circumference of the through hole 4a1 is formed by the integral molding method.
    The inner band links 3a, 4a and / or the outer band links 3b, 4b are each made of one of the materials: precious metals, alloys of precious metals, copper, copper alloys, stainless steels, aluminum, resins, ceramics and metallic glasses. At least tungsten carbide (WC), tantalum carbide (TaC), titanium carbide (TiC) and niobium carbide (NbC) can be cited as super-hard alloys. At least zirconium oxide ceramics, aluminum oxide ceramics and ceramics based on titanium nitride can be cited as ceramics. At least gold, platinum and silver can be cited as precious metals. As an alloy of precious metals, at least gold-containing alloys can be cited, with an 18-carat gold (K18), a 22-carat gold (K22) and a 24-carat gold (K24) also being able to be cited as an alloy containing gold. Aluminum also contains aluminum coated with an aluminum oxide film on the surface by anodizing.
    To produce a metallic glass, the metallic glass is made from a metallic glass containing a vitreous single metal phase, a metallic glass containing a vitreous single metal phase with a supercooled liquid temperature range of equal to or above 30 K at the rate of temperature increase of 0.67 K / s, a crystal with metallic glass having grain sizes equal to or below 100 nm and a glassy metal structure in a volume ratio equal to or above 50% containing metallic glass.
    The metallic glass containing a vitreous single metal phase and the metallic glass containing crystals with grain sizes equal to or below 100 nm have a microstructure which provides a smooth, even surface quality. Therefore, since there is no grain defect, the integrally molded band link units 3, 4 are enabled to be manufactured with a smooth flat surface. Furthermore, the product spread can safely be reduced. Consequently, the integrally molded band link units 3, 4 can be realized with a highly accurate shape.
    If the grain size of the crystals exceeds 100 nm, it exerts bad influences on the surface roughness (surface flatness) of the integrally formed band link units 3, 4. Therefore, it is desirable that the grain size of the crystals mixed in the microstructure of the metallic glass be equal to or below 100 nm.
    The metallic glass containing a glassy single metal phase with a supercooled liquid temperature range of equal to or above 30 K at the rate of temperature increase of 0.67 K / s has a high stability as a solid glass. Therefore, if inexpensive mold processing such as viscous flow cast molding or the like is used, the respective integrally molded band link units 3, 4 can be manufactured very easily and with high accuracy, and product scatter can be surely reduced.
    By producing the integrally formed band link units 3, 4 from a glassy metal structure containing metallic glass in a volume ratio equal to or greater than 50%, high dimensional accuracy and high durability can be achieved. Therefore, the respective integrally molded band link units 3, 4 can be manufactured with high accuracy, and at the same time, the durability of the integrally molded band link units 3, 4 can be increased.
    If the volume ratio of the glassy metal structure is less than 50%, sufficient flatness on the surfaces of the integrally formed band link units 3, 4 cannot be obtained. Therefore, it is desirable that the volume ratio of the glassy metal structure in the metallic glass is equal to or above 50%.
    By making the integrally molded band link units 3, 4 from the above various materials, a wrist watch band 1 which is not easily scratched can be produced.
    When the integrally molded band link units 3, 4 are made of a metallic glass, a metallic glass whose main component is one of Au, is preferred from the viewpoint of improving the texture quality and increasing the decorating possibilities in the external appearance of the wrist watch band 1 by gloss. Is Pt, Zr, Cu, Pd or Ti. As an example, e.g. B. a Pt-based metallic glass with the composition of Pt 48.75, Pd 9.75, Cu 19.5 and P 22 (at%) (Pt48.75Pd9.75Cu19.5P22 alloy) can be cited.
    After the integrally molded band link units 3, 4 are made from the above various materials, the respective surfaces of the inner band links 3a, 4a and the outer band links 3b, 4b are subjected to grinding, polishing and mirror finishing to give the respective surfaces a mirror finish is given. With the high-gloss finish, the respective surfaces are finished to a surface roughness of Ra ≤ 0.1 µm and Rz ≤ 0.4 µm, which creates a gloss as jewelery and gives the bracelet an even higher quality feel and an even more aesthetic satisfaction.
    When the material of the integrally molded band link units 3, 4 is a super hard material such as super hard alloy, ceramic or the like, the mirror finishing is carried out by grinding and polishing or the like by a diamond wheel. When manufacturing from a metallic glass, a desired surface roughness (Ra ≤ 0.1 µm and Rz ≤ 0.4 µm) can be achieved through the surface evenness specific to metallic glasses. Therefore, no special mirror finish is required on the surfaces of the integrally molded band link units 3, 4.
    It is also possible for the two integrally formed band link units 3, 4 to be processed at least on the surfaces as desired in such a way that the processes between integrally formed band link units differ from one another. In addition to high-gloss finishing, matting, satinizing, hairline finishing or the like can also be cited as any desired surface processing method. In the case of matting, it is sufficient that the surface of one of the integrally formed band link units is provided with unevenness by sandblasting. With the hairline finishing, uninterrupted lines are provided by a surface treatment. The satin finish provides interrupted lines through a surface treatment.
    For example, the surface of the integrally molded band link unit 3 is subjected to a mirror finish, and the surface of the other integrally molded band link unit 4 is subjected to matting, satin finishing or hairline finishing, whereby the respective integrally molded band link units 3, 4 with different from each other Surface textures can be provided and, moreover, new decoration options can be made possible for the external appearance of the wristwatch 1.
    Otherwise it is also possible that of two integrally formed band link units 3, 4, the inner band link 3a of an integrally formed band link unit 3 and the outer band link 4b of the other integrally formed band link unit 4 are processed at least on the surfaces in the same way, while the inner The band link 4a of the other integrally molded band link unit 4 and the outer band link 3b of the one integrally molded band link unit 3 can be machined at least on the surfaces other than the surface of the inner band link 3a of the one integrally molded band link unit 3. Any desired processing methods such as the aforementioned high-gloss finishing, matting, satin-finishing, hairline finishing and the like can be selected as the surface treatment method for this. This enables the two integrally molded band link units 3, 4 to be provided with surface finishes different from one another in such a way that the inner band links 3a, 4a and the outer band links 3b, 4b of the two integrally molded band link units 3, 4 cross each other, whereby for the external appearance the wristwatch 1 new decoration options can be made possible.
    It is also possible that the two integrally formed band link units 3, 4 are colored at least on the surfaces with different colors and are thus made identical except for the colors.
    As explained above, it is made possible that, by selecting the material for the integrally molded band link units 3, 4, the integrally molded band link units 3, 4 can be provided with various colors at least on the surfaces. The combination of the colors of the integrally molded band link units 3, 4 can be arbitrarily selected in consideration of the pattern of the wrist watch band 1, namely it is possible that the integrally molded band link units 3, 4 are made of the same material and provided with a uniform color or different Materials can be provided with differently defined colors.
    By producing the integrally formed band link units 3, 4 from zirconium oxide ceramic, it is possible for the integrally formed band link units 3, 4 to be provided with black, blue and pink color, respectively. By making the integrally molded band link units 3, 4 from WC, TiC, NbC, aluminum oxide ceramic, zirconium oxide ceramic or a titanium nitride-based ceramic, the integrally molded band link units 3, 4 can be provided with white color. In particular, the integrally formed band link units 3 and 4 can also be provided with a pearly white color by manufacturing them from zirconium oxide ceramic. By making the integrally molded band link units 3, 4 from a titanium nitride-based ceramic, the integrally molded band link units 3, 4 can be given a gold color. The above selection of the material makes it possible to provide the integrally formed band link units 3, 4 with different colors and thus to improve the texture quality and to increase the decoration options for the wrist watch band 1.
    To produce the integrally formed band link units 3, 4 from a super-hard alloy, alloy powder is press-formed and sintered at least by a tool, whereby a sintered molding approximated in the dimensions of the final shape of the finished product of the integrally formed band link units 3, 4 is obtainable. After the molding has been provided, it is sufficient that only a decorative surface polishing, chamfering or the like is provided in the external appearance. Without spark erosion and only by grinding and polishing the respective surfaces with a diamond wheel, a finished design and a high-gloss finish are easily possible. It is also possible that the integrally molded band link units 3, 4 are made of a super hard alloy by a powder injection molding method.
    When the integrally molded band link units 3, 4 are made of ceramics, the integrally molded band link units 3, 4 are also easily manufactured by the powder injection molding method.
    To produce the integrally molded band link units 3, 4 from a noble metal, an alloy of noble metals, copper or a copper alloy, the integrally molded band link units 3, 4 are produced by machining or injection molding. In order to manufacture the integrally molded band link units 3, 4 from a stainless steel, it is sufficient that the stainless steel is machined and thereby completed into an integrally molded band link units 3, 4 having a desired shape and dimensions.
    In order to manufacture the integrally molded band link units 3, 4 from metallic glass, the integrally molded band link units 3, 4 are manufactured by die-casting, injection molding, or mechanical working such as machining. However, die-casting or injection molding is preferred for the reasons that it allows the integrally molded band link units 3, 4 to be manufactured at low cost and with a high degree of shape reproducibility, thus being easy to manufacture with high dimensional accuracy, whereby the product spread can be safely reduced and an improvement mass productivity and at the same time a cost reduction can be achieved.
    When the integrally molded band link units 3, 4 are manufactured by die casting or injection molding, a mold is first prepared which is formed at least in the external appearance shape of the integrally molded band link units 3, 4 and in which a blind hole and a through hole of the integrally molded band link units 3, 4 are incorporated. Then one of the metallic glasses listed above is melted and poured into the mold and cooled. In this way, the integrally molded band link units 3, 4 having a predetermined shape and dimensions are manufactured by an integral molding process. In the present invention, injection molding is regarded as a kind of metal casting process and further includes a manufacturing process by molten metallic glass.
    Furthermore, the temperature of the molten metallic glass is set equal to or above the melting point. As for the melting method for the metallic glass, the method is not particularly limited. In injection molding, too, the temperature of the molten metallic glass is set equal to or above the melting point.
    As explained above, the integrally molded band link units 3, 4 having a predetermined shape, when made by die-casting or injection molding of metallic glass, can be made by a single molding work. This enables the integrally molded band link units 3, 4 to be offered with high mass productivity at a low cost.
    The base part 2a and the center plate 2b can be produced with high reproducibility by means of a cast molding, which is why the base part 2a and the center plate 2b can be produced with high quality.
    In order to prevent the metallic glass from shrinking in volume from the molten state, it is preferred that the metallic glass be cooled and hardened during molding at a cooling rate equal to or more than 300 ° C / sec.
    The blind bores 3b1, 4b1 and the through bores 3a1, 4a1 can be formed separately from each other by machining. Nevertheless, it is also possible and preferred that the blind bores 3b1, 4b1 and the through bores 3a1, 4a1 are formed together simultaneously by a one-piece molding process, the blind bores 3b1, 4b1 and the through bores 3a1, 4a1 being easy to manufacture with high accuracy.
    The assembly of the wrist watch strap 1 is explained below with reference to FIGS. 4 to 8. The integrally formed band link units 3 and 4 produced by the above methods and the separately provided two webs 5a, 5b are shown in the assembled state in FIGS. 4 to 7.
    According to FIG. 4, the respective ends of the web 5a are inserted and fitted into the respective blind bores 3b1, 4b1 of the integrally formed band link units 3 and 4, whereby the two outer band links 3b, 4b are connected to one another by the web 5a. The web 5a is introduced until the respective ends of the web 5a touch the respective bottom of the blind bores 3b1, 4b1. Since the web 5a is inserted into the blind bores 3b1, 4b1, the ends of the web 5a are not exposed to the outside of the wrist watch band 1. Thereby, the external appearance of the wrist watch band 1 can be improved. Since the inserted portion is not exposed outside, the inserted portion is not affected by wind and weather, whereby deterioration due to aging of the inserted portion can be prevented.
    From this state, at least one of the integrally molded band link units 3 and 4 or the two integrally molded band link units 3 and 4 is rotated such that the locking bar 3a3 engages the groove 4a2 and the locking bar 4a3 engages the groove 3a2, whereby, as from Figures 6 and 7, the locking strips 3a3, 4a3 are locked by engagement with one another and the two inner band members 3a, 4a are attached. Figure 5 illustrates an example of rotation of the integrally molded link units in which the other integrally formed link unit 4 is rotated in the direction of the arrow in the drawing.
    By fastening the two inner band links 3a, 4a, two integrally formed band link units 3 and 4 are arranged in a direction transverse to the longitudinal direction of the wrist watch band 1. When a tensile stress is applied from the outside, it can also be prevented that the inner band links 3a, 4a are separated from one another in the longitudinal directions of the web 5.
    The locking strips 3a3 and 4a3 engage one another, and at the same time a through-hole 3a1 and 4a1 is formed in an uninterrupted manner over the entire width of the two inner band members 3a, 4a, as can be seen from FIG. Then, as can be seen from Figure 6, a web 5b is inserted into this uninterrupted through-hole 3a1 and 4a1 so that the inner band links 3a, 4a and the outer band links 3b, 4b are assembled together and a band link block 2 shown in FIG. 1 is thus formed .
    By inserting the two ends of the web 5b guided through the through-hole 3a1, 4a1 into the blind hole of the outer belt link of another belt link block and by repeating the insertion, a plurality of belt link blocks 2 are in one direction to the longitudinal direction of the web 5a and 5b connected to one another in a transverse direction and thereby lengthened, as a result of which a wrist watch strap 1 according to FIG. In Fig. 8, one end of the wrist watch band 1 is connected to a wrist watch case 6 such as a clockwork and dial, and the other end of the wrist watch band 1 is connected to an unillustrated clasp. In the present invention, the longitudinal direction of the wristwatch denotes the direction in which the wristwatch band 1 continues and at the same time a plurality of (equal to or more than two) individual band link blocks 2 are connected to one another.
    As the fastening structure of the two inner band members 3a, 4a, another fastening structure besides the combination of the grooves 3a2, 4a2 with the locking strips 3a3, 4a3 can be selected, e.g. B. a combination of a projection with a hole that can be fitted on this projection is possible. If the two inner band links 3a, 4a can functionally be fastened to one another and if a tensile stress is applied in a longitudinal direction of the web 5a or 5b, a separation of the inner band members 3a, 4a in the longitudinal directions of the web 5 can be prevented, the fastening structure is not particularly limited.
    The entire body of the wrist watch is further formed by being provided with the wrist watch band 1.
    With the above structure of the wrist watch band 1 and the wrist watch provided with the wrist watch band 1, the use of adhesive can be dispensed with. By appropriately guiding the web 5a or 5b in the blind bores 3b1, 4b1 or the through bores 3a1, 4a1, the individual hinge link blocks 2 can be assembled. Adhesive is also not used to connect the individual band link blocks 2, which is why the reliability of the wrist watch band 1 and the wrist watch against deterioration due to aging can be increased.
    The components of the wrist watch band 1 other than the band links (inner band links 3a, 4a and outer band links 3b, 4b) are limited to only two webs 5a, 5b. Therefore, the component parts and the manufacturing processes are reduced, so the cost of the wrist watch band 1 and the wrist watch can be reduced. Corresponding to the reduction in the number of components, the fastening points of the components are also reduced, so that the risk of deterioration in quality due to aging is reduced. The risk of the wrist watch band 1 falling off the arm is also reduced. Thereby, the reliability of the entire wrist watch band 1 can be improved.
    The present invention is not limited to the aforementioned embodiment. Other embodiments are also possible, provided that the structure of the embodiments does not exceed the scope of the content specified in the respective patent claims. Although the present invention has been illustrated and explained mainly with reference to the specific embodiment, particularly with reference to drawings, those skilled in the relevant art can make various variations in the amount and other constructions from the aforementioned embodiment without departing from the technical spirit and aim of the present invention Add. As an example, the integrally molded band link units 3, 4 can also be formed in the shape of Figure 10 without edges of the integrally molded parts of the inner band link 3a, the outer band link 3b, the inner band link 4a and the outer band link 4b.
