[0008] An embodiment of the watch according to the present invention will be described with reference to Figures 1 to 7. In this embodiment, the watch is a wristwatch worn on the wrist (hereinafter simply referred to as "watch 100"). In Figure 1, the front surface of the band 2 is referred to as the "front surface" of the band 2, and the back surface not shown in Figure 1 is referred to as the "back surface" of the band 2. The extending direction of the band 2 is defined as the longitudinal direction of the band 2 ("longitudinal direction L" in Figure 1), and the short direction of the band 2 perpendicular to this longitudinal direction L is defined as the width direction of the band 2 ("width direction W" in Figure 1). The thickness direction of the band 2 (up and down direction in Figure 3, etc.) is defined as the "thickness direction H". Although the embodiments described below have various technically preferable limitations for carrying out the present invention, the scope of the present invention is not limited to the following embodiments and illustrated examples.

[0009] As shown in Figure 1, the clock 100 of this embodiment includes a clock body 1 and a band 2 connected to the case of the clock body 1 (hereinafter referred to as "body case 11"). The body case 11 is formed in a hollow, short column shape with openings at the top and bottom in the thickness direction H. The material forming the body case 11 is a metal material such as stainless steel (SUS), titanium, or aluminum. It is preferable that the body case 11 be made of a hard material with a certain degree of strength, but the material constituting the body case 11 is not limited to those exemplified here. The body case 11 may be made of various hard synthetic resins such as super engineering plastics such as polyarylate (PAR) or engineering plastics such as polyacetal (POM). In the illustrated example, the case in which the body case 11 and the clock body 1 equipped therewith are substantially circular in plan view is illustrated, but the shape of the body case 11 and the clock body 1 equipped therewith is not limited to a circular shape, and may be elliptical, rectangular, or the like.

[0010] Although not shown in the figures, a watch module is housed in the hollow portion of the main case 11. The watch module includes various components necessary for watch functions, such as a watch movement including an analog display mechanism for moving the hands, a digital display mechanism including a liquid crystal display unit, and a circuit section that controls the driving of these components. Various buttons and operating parts such as a crown may be provided on the outside of the main case 11. The opening on the front side (the visible side of the watch), which is one side of the main case 11 in the vertical direction, is closed by a cover member 12. The cover member 12 is a transparent crystal member formed from, for example, glass or transparent resin material. The opening on the back side (the non-visible side of the watch) of the main case 11 is closed by a back cover member (not shown). The back cover member may be integrally formed with the main case 11. A display section (not shown) for displaying the time and various information is provided on the surface of the main case 11. Note that Figure 1 is a schematic illustration of the watch body 1 and does not accurately show its specific shape or configuration.

[0011] As shown in Figure 1, band attachment portions 13 for connecting the band 2 to the main case 11 are provided on the outer part of the main case 11 at positions corresponding to the 6 o'clock and 12 o'clock positions in an analog watch. The band 2 is attached to each of the band attachment portions 13. Note that the shape of the band attachment portions 13 is not limited to the illustrated example. When an exterior component such as a bezel is attached to the main case 11, the band attachment portions to which the band 2 is attached may be provided on the exterior component, etc.

[0012] As shown in Figure 1, Band 2 includes a short band, which is the main band (first band 2a in Figure 1), and a long band, which is the pointed band (second band 2b in Figure 1). Hereafter, when simply referred to as Band 2, it includes both the first band 2a and the second band 2b. The first band 2a and the second band 2b each have a band body 21. The end of each band body 21 that connects to the main body case 11 is the attachment end (attachment end 22) that is attached to the band attachment portion 13 of the main body case 11, and Band 2 is connected to the watch body 1 by attaching the attachment end 22 to the band attachment portion 13. The shape of the attachment end 22 does not need to be limited to the illustrated example, as long as it corresponds to the shape of the band attachment portion 13.

[0013] The first band 2a is attached to the band attachment portion 13 at the 12 o'clock position of an analog watch. The first band 2a has an attachment end 22 on one end of the band body 21 that is attached to the main case 11, and a buckle 23 and a pin 24 on the other end. In the example shown in Figure 1, one pin 24 is provided approximately in the center of the width direction W (see Figure 1) of the band 2. A keeper loop 25 is inserted through the band body 21 of the first band 2a. The keeper loop 25 is formed in an annular shape and is movable along the longitudinal direction L of the band 2. In this embodiment, the buckle 23, pin 24 and keeper loop 25 are made of a metal material such as stainless steel (SUS), titanium, or aluminum. However, the materials used to form the buckle 23, pin 24 and keeper loop 25 are not limited to those exemplified herein.

[0014] The second band 2b is attached to the band attachment portion 13 on the 6 o'clock side of an analog watch. The second band 2b has an attachment end 22 on one end of the band body 21 that is attached to the main case 11. The band body 21 of the second band 2b has a row of rod holes 27 formed along the longitudinal direction L for engaging the rod 24. In this embodiment, as shown in Figure 1, the rod 24 is provided in approximately the center of the width direction W, and the rod holes 27 of the second band 2b are also formed in one row in the center of the width direction W of the band 2. If there are two or more rods 24, the rod holes 27 are also provided in two or more rows in the width direction W, for example, corresponding to the positions of the rods 24.

[0015] The band 2 of the embodiment (band body 21 of band 2) includes a first layer 3 and a second layer 4, as shown in Figure 2. Although Figure 2 shows a part of the second band 2b, the configuration of the band body 21 is the same for the first band 2a. The first layer 3 is located on the back side of band 2 (the side that contacts the arm, etc.), and the second layer 4 is provided so as to cover one surface of the first layer 3 (the front side of band 2, the side that is visible when worn, hereinafter referred to as "surface 31") and so as to cover at least a part of the side surface 32 of the first layer 3. In Figure 3, the second layer 4 provided on the surface surface 31, which is one surface of the first layer 3, is referred to as the upper surface portion 41, and the second layer 4 provided on the side surface 32 of the first layer 3 is referred to as the side surface portion 42. The side portion 42 is provided continuously from the top portion 41, and at least a part of the inner circumferential side surface 33 of, for example, the tsuku rod hole 27 is also covered by the second layer 4, which is provided continuously from the top portion 41. In the following, when simply referred to as the second layer 4, it includes the top portion 41 and the side portion 42. In Figure 3, an example is shown in which the side portion 42 of the second layer 4 covers approximately half of the side surface 32 of the first layer 3 in the thickness direction H, but the range in which the side portion 42 is provided is not limited to the illustrated example. The side portion 42 may cover almost the entire thickness direction H of the side surface 32 of the first layer 3.

[0016] Among the layers constituting the band body 21 of the band 2, the first layer 3 is a layer containing, for example, a silicone rubber system and is a relatively soft layer. The silicone rubber maintains a substantially constant softness even when the temperature changes. By making the layer containing the silicone rubber system the first layer 3 disposed on the back side (the inner side in contact with the arm) of the band 2, when the band 2 is worn on the arm, it can fit well with the arm and provide a good feeling of contact with the skin. In addition, the silicone rubber has the property of being difficult to slip, and is also easy to return to its original shape even when compressed and deformed, and has the characteristic of being difficult to deteriorate due to expansion and contraction. Therefore, it is suitable as a constituent material of the band 2 for which attachment and detachment are repeated.

[0017] Also, the second layer 4 is a layer having higher wear resistance than the first layer 3 and is a layer containing, for example, a urethane-based resin (for example, thermoplastic polyurethane). Specifically, for example, a urethane resin sheet having a thickness of about 0.3 mm is applied as the second layer 4. Even when the first layer 3 is made of a relatively soft material, by covering at least a part of the surface 31 (one surface) and the side surface 32 (including the inner peripheral side surface 33 of the insertion rod hole 27) of the first layer 3 with the second layer 4 containing a urethane-based resin, the band 2 can be made resistant to scratches and abrasions when the band 2 falls or rubs against the outside, and it is possible to prevent the deterioration of the appearance quality. In particular, in the embodiment, since the side surface portion 42 is continuously provided with the upper surface portion 41, it is difficult for only the upper surface portion 41 to peel off or only the side surface portion 42 to peel off, and the entire second layer 4 can firmly protect the first layer 3. The second layer 4 only needs to be a layer formed of a material having higher wear resistance than the first layer 3, and the materials constituting the first layer 3 and the second layer 4 are not limited to those exemplified here. For example, although the second layer 4 has high wear resistance, it is necessary for the band 2 composed of the first layer 3, the second layer 4, etc. to have a flexibility such that the band 2 can be wound around an arm or the like. The first layer 3 and the second layer 4 are formed of a material that can withstand bending to the extent that it can be aligned along an arm or the like.

[0018] The second layer 4 is preferably transparent or translucent. If the second layer 4 is transparent or translucent, a decorative layer 5 may be provided between the first layer 3 and the second layer 4 (see Figures 4 to 7). For example, Figures 4 to 7 are schematic diagrams illustrating the structure of the band 2 in the embodiment, and the layer thicknesses of each layer constituting the band 2 shown in the illustrated examples do not reflect the actual layer thicknesses.

[0019] When a decorative layer 5 is provided between the first layer 3 and the second layer 4, the layer structure will be as shown in Figure 4, for example. The decorative layer 5 may be a printed layer 5a formed by printing with ink, or a vapor-deposited layer 5b formed by vapor-depositing indium, etc. The printed layer 5a and vapor-deposited layer 5b are thin layers, for example, about 3 nm in thickness. For example, if a metallic-looking decorative layer 5 such as gold or silver is provided by printing or vapor deposition, then, for example, when the watch body 1 is made of metal, or when the buckle 23, pin 24, loop 25, etc. of the band 2 are made of metal, the metallic parts and the band 2 can be unified in a metallic look without any sense of incongruity, and an appearance can be achieved as if the entire watch 100, including the band 2, is made of metal.

[0020] On the printing layer 5a, a printing portion 7 such as various logos and patterns may be further provided with ink or the like of a color different from that of the main body of the printing layer 5a (see FIG. 5). When a vapor deposition layer 5b is provided as the decorative layer 5 between the first layer 3 and the second layer 4, for example, the layer structure as shown in FIG. 6 is obtained. Also in this case, as shown in FIG. 6, the vapor deposition layer 5b may be further provided with a printing portion 7 formed by printing various logos and patterns or the like. Note that when the vapor deposition layer 5b is provided, it is not limited to indium vapor deposition. Also, the specific method of providing the vapor deposition layer 5b is not particularly limited. Further, various parts 8 (for example, dried flowers, lame, etc.) may be inserted into the decorative layer 5 (printing layer 5a or vapor deposition layer 5b) instead of the printing portion 7 formed by printing. Even when the decorative layer 5 is provided in this way, by providing a transparent or translucent urethane-based resin thereon, the printing layer 5a or the vapor deposition layer 5b, which is the decorative layer 5, can be protected, and when the printing portion 7 or the parts 8 are provided on the printing layer 5a or the vapor deposition layer 5b, it is also possible to prevent these from peeling or being damaged. Therefore, the appearance quality of the band 2 can be maintained for a long time.

[0021] Note that an adhesion layer 6 may be provided between the first layer 3 and the second layer 4. For example, the first layer 3 formed of a silicone rubber-based material has a relatively smooth surface and is difficult to absorb ink or the like. Therefore, when the decorative layer 5, which is the printing layer 5a or the vapor deposition layer 5b, is directly provided on the first layer 3, the decorative layer 5 may be easily peeled off or the decorative layer 5 may not be formed with a uniform thickness. Therefore, when the decorative layer 5 is provided between the first layer 3 and the second layer 4, it is preferable to first perform a primer treatment (printing a predetermined liquid agent or the like) on the first layer 3 to form the adhesion layer 6, and then stack the decorative layer 5 and the second layer 4, which is a layer of a urethane-based resin, thereon. Thereby, the layer stacked on the first layer 3 can be firmly fixed and the adhesion can be enhanced. Therefore, it is possible to effectively prevent the first layer 3, the decorative layer 5, and the second layer 4 from peeling and separating.

[0022] Next, the operation of the band 2 according to the embodiment and the watch 100 equipped with the band 2 will be described. In the embodiment, the band 2 is formed by first forming a first layer 3 from a relatively soft silicone rubber-based material, then forming an adhesion layer 6 on the surface 31 (one side) of the first layer 3 and at least a part of the side surface 32 of the first layer 3 by priming, and then forming a decorative layer 5 on top of the adhesion layer 6. Specifically, a printed layer 5a is formed by printing, or a vapor-deposited layer 5b is provided by vapor-depositing indium or the like. Printed parts 7 such as logos may be further added to the printed layer 5a or vapor-deposited layer 5b by printing, or three-dimensional decoration may be applied by arranging parts 8 such as dried flowers or glitter. After the decorative layer 5 is provided, a second layer 4 is continuously formed so as to cover the surface 31 (one side) of the first layer 3 and at least a part of the side surface 32 of the first layer 3. Specifically, the band 2 (the band body 21 of the first band 2a and the second band 2b) is molded (for example, by compression molding) by covering at least a portion of the surface 31 (one side) of the first layer 3 on which the decorative layer 5 is provided, and the side surface 32 of the first layer 3, with a transparent or translucent urethane resin sheet or the like. At this time, if there is a hole opening on the surface side of the band 2, such as a rod hole 27, the second layer 4 is also formed on at least a portion of the inner circumferential side surface 33 of the hole (see Figure 3).

[0023] Of the band bodies 21 formed in this way, a loop 25 is inserted through the band body 21 of the first band 2a. A buckle 23 and a pin 24 are attached to the end of the band body 21 opposite to the attachment end 22 (the free end). The attachment end 22 of the first band 2a is attached to the band attachment part 13 on the 12 o'clock side of the watch body 1, and the attachment end 22 of the second band 2b is attached to the band attachment part 13 on the 6 o'clock side of the main case 11 of the watch body 1. This completes the watch 100 with the band 2 (see Figure 1). When wearing the watch 100 on a wrist or the like, the free end of the second band 2b is inserted into the buckle 23 provided on the free end side of the first band 2a, and the pin 24 of the buckle 23 is locked into one of the pin holes 27. This connects the first band 2a and the second band 2b. In this state, the free end of the second band 2b, which has excess length and overlaps with the first band 2a, is inserted into the keeper ring 25.

[0024] When the watch 100 according to this embodiment is worn on the wrist, the inner surface of the band 2 that touches the skin is exposed to the first layer 3, which is made of a soft silicone rubber-based material, providing a comfortable feel against the skin and excellent fit to the wrist. On the other hand, the outer part of the band 2 when worn is continuously covered by the second layer 4, which has higher abrasion resistance than the first layer 3, not only on the surface 31 of the first layer 3 but also on at least a part of the side surface 32 (including the inner circumferential side surface 33 of the buckle hole 27), making the band 2 resistant to scratches and abrasions. For example, even if the band 2 is repeatedly attached and detached, metal components such as the buckle 24 and the loop 25 can prevent the sides of the band 2, the inner circumferential side surface 33 of the buckle hole 27, and the edges from being scraped or scratched. Furthermore, even if a decorative layer 5 is provided between the layers constituting the band 2 (the first layer 3 and the second layer 4) by printing or vapor deposition, it is possible to prevent the printing from fading or peeling off and deteriorating. Thus, since the band 2 according to the embodiment can maintain its excellent appearance for a long time, the appearance of the watch 100 to which the band 2 according to the embodiment is attached will also remain beautiful and can be enjoyed for a long time.

[0025] As described above, the band 2 according to the embodiment includes a first layer 3, a second layer 4 which is continuously provided on one surface of the first layer 3 (the surface 31 of the first layer 3) and at least a part of the side surface 32 of the first layer 3, and which has higher wear resistance than the first layer 3. For example, in the case of the band 2 of a watch 100 as shown in the embodiment, by exposing the relatively soft first layer 3 on the back side of the band 2, which is the side that comes into contact with the wrist when the band 2 is worn, the band 2 can be made to feel good against the skin and conform well to the skin, resulting in a band 2 that is comfortable to wear. Furthermore, by covering the surface 31 and a part of the side surface 32 (including the inner circumferential side surface 33 of the ferrule hole 27) of the first layer 3 with the second layer 4 which has higher wear resistance than the first layer 3, the surface 31 of the first layer 3 etc. are not exposed as the outermost layer of the band 2, and the outer layer portion of the band 2 can be prevented from being worn or scratched. In particular, as in the embodiment, when the buckle 23, pin 24, and keeper 25 are made of metal, the surface 31 and side 32 of the first layer 3 become prone to wear and damage as the band 2 is repeatedly attached and detached. In this regard, the second layer 4 continuously covers the surface 31 and part of the side 32 of the first layer 3, improving the abrasion resistance of the band 2 against rubbing from the front and sides, and effectively preventing wear and damage caused by the band 2 being dropped or rubbed by the movement of the keeper 25. This allows the appearance quality of the band 2 to be maintained for a longer period of time.

[0026] In this embodiment, the first layer 3 is a layer containing a silicone rubber-based material, and the second layer 4 is a layer containing a urethane-based resin. Silicone rubber is relatively soft and maintains a nearly constant softness even when the temperature changes. Therefore, by making the first layer 3, which is placed on the back side of the band 2 (the inner side that contacts the arm), a layer containing a silicone rubber-based material, the wearing comfort of the band 2 is improved. Also, because silicone rubber has a non-slip property, it can prevent the band 2 from rotating around the arm. Furthermore, since silicone rubber is resistant to deterioration due to stretching, the band 2 is less likely to deteriorate even if it is repeatedly attached and detached. On the other hand, because silicone rubber is soft, it is easily abraded and scratched, but as in this embodiment, the second layer 4, which contains a urethane-based resin that has higher abrasion resistance than the first layer 3, continuously covers at least a portion of the front surface (surface 31) and side surface 32 of the first layer 3. As a result, the band 2 becomes more resistant to scratches and abrasions, preventing deterioration of its appearance. Furthermore, by providing the second layer 4 only on at least a portion of the surface 31 and side surface 32 of the first layer 3, and not on the back surface, the band 2 can be reinforced without compromising the effects achieved by the first layer 3, such as ease of conforming to the arm, and good feel and fit.

[0027] Furthermore, the second layer 4 in this embodiment is a transparent or translucent layer, and a decorative layer 5 is provided between the first layer 3 and the second layer 4. This makes the decorative layer 5, which is the printed layer 5a or the vapor-deposited layer 5b, visible from the outside, enabling the creation of a band 2 with excellent design. Moreover, since the decorative layer 5 is provided beneath the highly abrasion-resistant second layer 4, it prevents the design, such as patterns applied by printing or vapor deposition, from peeling or being damaged and deteriorating over time, thus maintaining an aesthetically pleasing appearance for a long period of time.

[0028] In addition, in the embodiment, an adhesion layer 6 may be provided between the first layer 3 and the second layer 4. For example, the first layer 3, which is made of a silicone rubber material, has a relatively smooth surface and does not easily absorb ink, making it difficult for the printed layer 5a and the vapor-deposited layer 5b to adhere. In this regard, by first applying a primer treatment on the first layer 3 to form an adhesion layer 6, and then layering the decorative layer 5 and the second layer 4, which is a urethane resin layer, on top of it (see Figures 4 to 7), the adhesion of the layers layered on top of the first layer 3 can be improved, and the decorative layer 5 and the second layer 4 can be prevented from peeling off and separating from the first layer 3.

[0029] Furthermore, in this embodiment, the band 2 is provided with a rod hole 27 for securing the rod 24, and at least a portion of the inner circumferential surface 33 of the rod hole 27 is covered with the second layer 4. For example, if the rod 24 is made of a metal material as in this embodiment, the inner circumferential surface 33 of the rod hole 27 is prone to being scraped or damaged by the rod 24 as the band 2 is repeatedly attached and detached. In this regard, as in this embodiment, a highly wear-resistant second layer 4 is also provided on the inner circumferential surface 33 of the rod hole 27, which helps to suppress damage to the rod hole 27 portion.

[0030] Furthermore, when the band 2 described above is attached to the watch body 1 to form a watch 100 (wristwatch, etc.), the quality of the appearance of the band 2 can be maintained for a long time while maintaining a comfortable fit, and the overall appearance and design of the watch 100 can also be well maintained. In addition, if, for example, a metallic decorative layer 5 is provided between the first layer 3 and the second layer 4, it is possible to achieve an appearance as if the watch had a metal band, creating a sense of luxury. In this case as well, since the band body 21 is actually made of silicone rubber or urethane resin, it is possible to create a watch with a band 2 that is lighter and easier to handle than a metal band 2.

[0031] Although embodiments of the present invention have been described above, it goes without saying that the present invention is not limited to these embodiments and can be modified in various ways without departing from its essence. For example, in the above embodiments, as shown in Figure 3, etc., the band 2 comprises a first layer 3 and a second layer 4, and the outermost layer on the surface side of the band 2 is the second layer 4, but the configuration of the band 2 is not limited to this. For example, a top coat layer may be further provided on the surface side of the second layer 4. The top coat layer is, for example, a transparent coating layer, and by providing a top coat layer, the glossiness of the surface of the band 2 can be adjusted, such as making the band 2 more glossy or, conversely, matte.

[0032] Furthermore, in the above embodiment, as shown in Figures 4 to 7, the band 2 (band body 21 of band 2) has an adhesion layer 6 and a decorative layer 5 between the first layer 3 and the second layer 4. However, the layer configuration of the band 2 (band body 21 of band 2) is not limited to that shown in the embodiment. The band 2 only needs to have at least the first layer 3 and the second layer 4, and may not have the adhesion layer 6 or the decorative layer 5, for example, as shown in Figure 3. In this case as well, it is possible to achieve both the ease of attachment of the first layer 3, which is made of silicone rubber or the like, and the wear resistance and durability that maintains the appearance of the band 2 in good condition by preventing scratches and abrasions of the first layer 3 with the second layer 4.

[0033] Furthermore, the band 2 is not limited to being divided into a first band 2a and a second band 2b, but may also be, for example, a continuous strip-shaped band. In this case, for example, an attachment part for passing the band 2 through may be provided on the back side of the watch body, and the band may be attached to the watch body by passing the band through the attachment part. For example, if the attachment part on the watch body side is made of a hard material such as metal, the surface and sides of the band may rub against the attachment part and become worn or scratched each time the band is attached or removed. However, since at least a part of the surface and sides of the band (the band body) is covered with a second layer 4 which has excellent wear resistance, it is less likely to get scratched and the beautiful appearance can be maintained for a long time.

[0034] Furthermore, in the above embodiment, the example given was that the band 2 is a hole-fastening type band that includes a rod 24 and a rod hole 27, and the first band 2a and the second band 2b are connected by locking the rod 24 into one of the rod holes 27. However, it is not essential that the band 2 includes a rod 24 and a rod hole 27. The band may also be configured to connect the first band 2a and the second band 2b by projections other than the rod 24, locking means, etc.

[0035] Furthermore, Band 2 can be applied as a band for a wide range of devices worn on the wrist or other body parts, and is not limited to being a band used for devices with watch functions. Band 2 may have various functions such as a pedometer, heart rate monitor, altimeter, and barometer, or it may be applied to so-called smartwatches, etc.

[0036] Although several embodiments of the present invention have been described above, the scope of the present invention is not limited to the embodiments described above, but includes the scope of the invention as described in the claims and its equivalents. [Explanation of symbols]
