[0008] First, the configuration of the band 100 and the watch 150 will be explained with reference to Figures 1 and 2.

[0009] As shown in Figure 1, the band 100 is composed of a first band 10, a second band 15, and a clasp 35 that connects the first band 10 and the second band 15. The first band 10 is attached to one end of the watch body 1 (see Figure 2). The second band 15 is attached to the other end of the watch body 1.

[0010] The clasp 35 is composed of a cover member 30, an adjustment part 80, a middle plate 31, and a lower plate 32. The clasp 35 is configured to unfold and extend as shown in Figure 1 when the latch pin 41 is released by pressing the buttons 33 provided on both sides of the cover member 30.

[0011] As shown in Figure 2, the end of the first band 10 is connected to the lug 5 located on the 12 o'clock side of the watch 150. Similarly, the end of the second band 15 is connected to the lug 6 located on the 6 o'clock side of the watch 150. In Figure 2, the watch 150 is shown as a three-hand analog watch, but it is not limited to this; any device worn on the wrist is acceptable, such as a digital watch or a smartwatch.

[0012] As shown in Figure 1, the first band 10 is composed of multiple connected pieces 2, etc. The end pieces 2b at the ends of the first band 10 are connected to the adjustment section 80 inside the cover member 30 via connecting pieces 11. The adjustment section 80 will be described later.

[0013] The second band 15 is composed of multiple connected pieces 2, etc. The end piece 2c at the end of the second band 15 is connected to one end of the bottom plate 32. The bottom plate 32 is provided with a latch pin 41. The other end of the bottom plate 32 is connected to one end of the middle plate 31. The other end of the middle plate 31 is connected to one end of the cover member 30.

[0014] The lower plate 32 is rotatably connected to the end piece 2c of the second band 15 and to one end of the middle plate 31. The middle plate 31 is rotatably connected to one end of the cover member 30 and to the other end of the lower plate 32. The clasp 35 is configured to switch between a state in which the cover member 30, the middle plate 31 and the lower plate 32 are folded in a Z shape and a state in which they are unfolded and extended.

[0015] The cover member 30 is a buckle and has a curved shape overall to facilitate attachment to the arm. The cover member 30 is roughly rectangular in plan view, and its longitudinal direction is aligned with the extending direction of the first band 10. The width of the cover member 30 in the short direction is approximately the same as the width of the first band 10. The middle plate 31 and the bottom plate 32 have a similar curvature to the cover member 30, following the back surface of the cover member 30 when folded.

[0016] In the preferred example, each component of the band 100 is made of titanium. However, it is not limited to titanium; any hard metal with a good texture may be used, for example, stainless steel.

[0017] Next, the configuration of the adjustment section 80 will be explained with reference to Figures 3 to 6. Note that Figure 3 is a transparent perspective view showing the configuration of the clasp 35. Figures 5 and 6 omit the illustration of the spring 26.

[0018] As shown in Figure 3, the adjustment unit 80 is composed of a pair of rails 20 and 21, an adjustment piece 72, a pressing part 73, and an engagement pin 27 as an engagement part.

[0019] The rail 20 is a rail-shaped member arranged along the side wall 30a of the cover member 30. One end of the rail 20 is provided with a through hole 20a (see Figure 4) for connecting to the middle plate 31. The other end of the rail 20 is provided with a fixing hole 20b (see Figure 4) for fixing the rail 20 to the side wall 30a. Four grooves 29 for length adjustment, which serve as engaging parts, are provided at equal intervals on the side of the fixing hole 20b.

[0020] Rail 21 is a component that is paired with rail 20 and is positioned along the side wall 30b of cover member 30. Rail 21 has the same configuration as rail 20. Specifically, one end of rail 21 is provided with a through hole 21a (see Figure 4) for connecting to the middle plate 31, and the other end is provided with a fixing hole 21b (see Figure 4) for fixing rail 21 to the side wall 30b. Similarly, rail 21 is also provided with four grooves 29 for length adjustment, which serve as engaging parts.

[0021] As shown in Figure 4, the adjustment piece 72 is a connecting portion and has a projection 22a that protrudes toward the first band 10 side, and two branched projections 72b and 72c on the opposite side of the projection 22a.

[0022] The projection 22a is provided with a through hole 4 for connecting with the connecting piece 11. The adjustment piece 72 is positioned between the rail 20 and the rail 21. The connecting piece 11, which connects the adjustment piece 72 and the end piece 2b of the first band 10, is also formed to be approximately the same size as the adjustment piece 72 (see Figure 3). The connecting piece 11 is positioned between the rail 20 and the rail 21.

[0023] As shown in Figure 4, the portions of the protrusions 72b and 72c that come into contact with the pressing portion 73 are formed at a lower level. This lowered portion is referred to as the first surface 76. Through holes 28 are provided in the protrusions 72b and 72c.

[0024] The pressing section 73 consists of a pressing case 74, a lid 75, and two springs 26. The pressing case 74 has a storage section 74a for housing the two springs 26 and a part of the lid 75. The storage section 74a has an elongated hole 74b, which is an oval-shaped guide hole. On the back side of the storage section 74a, there is a bottom surface 65 that is lower than the base portion of the pressing case 74.

[0025] As shown in Figure 6, the bottom surface 65 of the pressing case 74 is provided with a groove 78 that engages with the engagement pin 27 (see Figure 4). The island-shaped projection with the bottom surface 65 is housed in the storage section 47 (see Figure 4) between the two projections 72b and 72c of the adjustment piece 72 (see Figure 4). On both sides of the bottom surface 65 are second surfaces 66 (see Figure 6) that are one step lower than the bottom surface 65. The two second surfaces 66 correspond to the two first surfaces 76 of the adjustment piece 72.

[0026] As shown in Figure 4, the spring 26 is an elastic member, and in a preferred example, a conical spring is used. The material of the spring 26 is, for example, piano wire. Any material that can provide the required spring force is acceptable, and for example, hard steel wire or stainless steel wire may be used. By using a conical spring, the contact height during compression can be reduced compared to a normal coil spring, so the pressing part 73 and the adjustment part 80 can be made more compact.

[0027] As shown in Figure 6, the lid 75 is provided with two mounting sections 77 for accommodating two springs 26. A shaft 75a is provided between the two mounting sections 77. The shaft 75a is a projection that rises from the base of the lid 75. The planar shape of the shaft 75a is oval. An elongated hole 68 is provided on the side of the shaft 75a through which the engagement pin 27 is inserted.

[0028] The shaft 75a is inserted through the elongated hole 74b of the pressing case 74. With the shaft 75a inserted, the engagement pin 27 is inserted through the elongated hole 68 of the shaft 75a. The length of the elongated hole 68 is set to allow the spring 26 to expand and contract with the engagement pin 27 inserted. The shaft 75a acts as a guide member to smooth the movement of the pressing case 74 as it moves up and down in conjunction with the expansion and contraction of the spring 26.

[0029] Specifically, with the two springs 26 set on the two mounting portions 77 of the lid 75, the lid 75 and the pressing case 74 are combined to form the pressing portion 73. Then, as shown in Figure 4, the pressing portion 73 is set in the storage portion 47 of the adjustment piece 72. With the pressing portion 73 housed in the storage portion 47 of the adjustment piece 72, the engaging pin 27 is inserted through the through hole 28 of the projection 72b, the elongated hole 68 of the shaft 75a, and the through hole 28 of the projection 72c, thereby integrating the pressing portion 73 and the adjustment piece 72.

[0030] Next, the method for adjusting the length of band 100 will be explained with reference to Figures 7 to 10.

[0031] As shown in Figure 7, the pressing portion 73 is pressed down by the restoring force of the two springs 26, which pushes down the bottom surface of the storage portion 74a, and presses the engaging pin 27 which is fitted into the groove 78 of the bottom surface 65 (see Figure 6). As shown in Figure 8, when the central fastener 35 is deployed, the adjustment piece 72 does not stand upright but is housed inside the cover member 30.

[0032] Specifically, the spring 26 biases the lid 75 and the pressing case 74 away from each other, causing the second surface 66 of the pressing case 74 to press against the first surface 76 of the projections 72b and 72c of the adjustment piece 72. This is because, due to the lever principle, the end of the adjustment piece 72 on the connecting piece 11 side is pressed against the cover member 30 side. In other words, the second surface 66 of the pressing case 74, the first surface 76 of the adjustment piece 72, and the related mechanism function as an anti-uprighting mechanism.

[0033] As shown in Figure 9, when adjusting the length of the band 100, the first band 10 is pulled downwards on the cover member 30 while in the unfolded state. When the pulling force exceeds the pressure applied by the pressing part 73, the tips of the projections 72b and 72c of the adjustment piece 72 push up against the second surface 66 of the pressing case 74, causing the adjustment piece 72 to stand upright.

[0034] When the adjustment piece 72 is in an upright position, pushing it towards the cover member 30 compresses the two springs 26 inside the pressing part 73, causing the engagement pin 27 to separate from the groove 29 and become slidable, as shown in Figure 10.

[0035] Here, with the adjustment piece 72 pushed in, the engagement pin 27 is moved from one of the four grooves 29 to the groove 29 at the desired length, and then the adjustment piece 72 is released, causing the engagement pin 27 to engage with that groove 29. In other words, when adjusting the length of the band 100, the adjustment piece 72 is raised with the clasp 35 unfolded and pushed towards the cover member 30.

[0036] In this embodiment, the lid 75 is made of resin. In a preferred example, polyacetal resin (POM) is used. However, it is not limited to polyacetal resin; any resin with good sliding properties may be used, for example, MC nylon, ultra-high molecular weight polyethylene, or Teflon® resin.

[0037] Next, the internal structure of the cover member 30 in the clasp 35 will be described with reference to Figure 11.

[0038] As shown in Figure 11, a lid 75 is positioned inside the cover member 30. The lid 75 is made of colored resin. The end face of the shaft 75a of the lid 75 is exposed in the center of the inside of the cover member 30. For example, if red resin is used for the lid 75, an oval-shaped red accent decoration can be applied to the inside of the cover member 30. Note that the color is not limited to red, and can be selected as appropriate according to the design.

[0039] Furthermore, rails 20 and 21 are exposed and positioned on the back side of the cover member 30. The rails 20 and 21 are provided with scales 200 that indicate the positions where multiple grooves 29 engage with the engagement pins 27 (see Figure 3). The pressing case 74, positioned inside the rails 20 and 21, is provided with an indicator display unit 300 that points to the scales 200. Specific examples of these scales 200 and indicator display unit 300 will be described later.

[0040] As shown in Figure 11, the clasp 35 includes a cover member 30, an engaging portion, and a movable member. The engaging portion is located on the back side of the cover member 30 and is fixed to the cover member 30. The engaging portion is, for example, a groove 29 provided in the rails 20 and 21.

[0041] The movable member is connected to the first band 10 and is movably mounted relative to the cover member 30. The movable member is a pressing part 73 and an adjustment piece 72 that acts as a connecting part. The movable member also has an engagement pin 27 that acts as an engaging part. The engagement pin 27 can selectively engage with any of the multiple grooves 29.

[0042] As shown in Figure 11, the clasp 35 is provided with a scale 200 that indicates the position where multiple grooves 29 and engaging pins 27 (see Figure 3) engage, in a plan view from the back side of the cover member 30. Specifically, the clasp 35 is located on the back side of the cover member 30 and has rails 20 and 21 that are arranged along the longitudinal direction of the cover member 30. The scale 200 is formed on the rails 20 and 21.

[0043] The scale 200 includes either lines, marks, or numbers. In this embodiment, the scale 200 is a line. The scale 200 is provided in four locations corresponding to the grooves 29. However, the scale 200 is not limited to being provided in four locations; it is desirable that it be provided in a number corresponding to the number of grooves 29. The marks include, for example, "○", "×", "△", and other shapes. The scale 200 is provided, for example, with a recessed area within the frame. However, it is not limited to being recessed; it may also be flat.

[0044] The movable member is provided with an indicator display unit 300 that indicates the scale 200. Specifically, the indicator display unit 300 is provided on the base portion of the pressing case 74, which is visible from the back side of the cover member 30.

[0045] The indicator unit 300, like the scale 200, includes either a line or a mark. In this embodiment, the indicator unit 300 is a triangular mark. The indicator unit 300 has two parts: one that indicates the scale 200 formed on the rail 20, and another that indicates the scale 200 formed on the rail 21.

[0046] As described above, the clasp 35 is provided with a scale 200 that indicates the position where the groove 29 and the engaging pin 27 engage. Therefore, when a user adjusts the length of the band 100, they can easily determine which groove 27 is engaged with. Thus, the length of the band 100 can be easily adjusted.

[0047] Furthermore, since the grooves 29 and scales 200 are formed on the same rails 20 and 21, any misalignment between the grooves 29 and the scales 200 can be eliminated. Also, because lines and symbols are used as scales, they can be formed relatively easily, such as by laser processing.

[0048] Furthermore, since the pressing case 74, which is a movable member, is provided with an indicator display section 300, it is possible to adjust the indicator display section 300 in correspondence with the scale 200, making it easy to understand visually. Also, since the indicator display section 300 is made of lines or symbols, it can be manufactured relatively easily, for example, by laser processing. In addition, the indicated position is easy to understand.

[0049] Next, the configuration of clock 150 will be explained with reference to Figures 12 to 17. Note that components identical to those in Figures 1 to 11 are given the same numbers.

[0050] As shown in Figure 12, the watch 150 includes a band 100. The band 100 has a first band 10 and a second band 15. The first band 10 is attached to one end of the watch body 1. The second band 15 is attached to the other end of the watch body 1.

[0051] As shown in Figure 13, the watch 150 has a first band 10, a second band 15, and a clasp 35 connecting the first band 10 and the second band 15. As shown in Figure 14, the watch 150 has a watch body 1, a first band 10, a second band 15, and a clasp 35 connecting the first band 10 and the second band 15. As shown in Figure 15, the watch 150 has a watch body 1, a first band 10, a second band 15, and a clasp 35 connecting the first band 10 and the second band 15.

[0052] As shown in Figure 16, the watch 150 includes a watch body 1, a first band 10 connected to the watch body 1, and a clasp 35 connected to the first band 10. As shown in Figure 17, the watch 150 includes a watch body 1, a second band 15 connected to the watch body 1, and a clasp 35 connected to the second band 15.

[0053] Next, the configuration of the band 100 will be explained with reference to Figures 18A to 20B. Figures 18A to 20B show the clasp 35 in the unfolded state.

[0054] As shown in Figures 18A and 18B, the band 100 has a first band 10, a second band 15, and a clasp 35 connecting the first band 10 and the second band 15. The clasp 35 has a cover member 30, an intermediate plate 31, and a bottom plate 32.

[0055] As shown in Figures 19A, 19B, 20A, and 20B, the band 100 has a first band 10, a second band 15, and a clasp 35 connecting the first band 10 and the second band 15. The clasp 35 has a cover member 30, a middle plate 31, and a bottom plate 32.

[0056] Next, the configuration of the clasp 35 will be explained with reference to Figures 21 to 26.

[0057] As shown in Figure 21, the central stopper 35 includes a cover member 30, a pair of rails 20 and 21 positioned inside the cover member 30, and a pressing case 74 positioned between the rails 20 and 21. The rails 20 and 21 are provided with scales 200. The pressing case 74 is provided with an indicator display section 300 that indicates the scales 200 at the end of the moving member, i.e., the end of the pressing case 74.

[0058] As shown in Figure 22, the clasp 35 has a cover member 30. As shown in Figure 23, the clasp 35 has a cover member 30. As shown in Figure 24, the clasp 35 has a cover member 30. As shown in Figure 25, the clasp 35 has a cover member 30. As shown in Figure 26, the clasp 35 has a cover member 30.

[0059] Next, with reference to Figures 27 to 53, the configuration of the other scales 200 and the other indicator units 300 in the clasp 35 will be described in detail.

[0060] As shown in Figure 27, the central stopper 35A has the scale 200A provided on only one side of the rails 20 and 21. Specifically, the scale 200A is provided only on rail 20. However, it is not limited to rail 20; the scale 200A may also be provided only on rail 21. In addition, the pressing case 74 has an indicator display section 300 only on the rail 20 side. The area within the frame of the scale 200A may be recessed or flat.

[0061] As shown in Figure 28, the clasp 35B has a scale 200B composed of a combination of lines and numbers. For example, when the band 100 is shortest, the line is combined with "1". As the length of the band 100 increases, the line is combined with "2", "3", and "4". Note that the scale 200B is not limited to being provided only on rail 20, but may be provided only on rail 21, or on both rails 20 and 21. The area within the scale 200B frame may be recessed or flat.

[0062] As shown in Figure 29, the clasp 35C has the 200C mark represented by a white outline. Specifically, the width of the white outline widens as the length of the band 100 is adjusted to be longer. The area within the 200C mark may be recessed or flat.

[0063] As shown in Figure 30, the clasp 35D represents the scale 200D with the number of lines. Specifically, the number of lines increases as the length of the band 100 is adjusted to be longer.

[0064] As shown in Figure 31, the clasp 35E represents the 200E mark with the length of a white outline. Specifically, the length of the line increases as the length of the band 100 is adjusted to be longer. Note that it is not limited to being represented by a white outline; it may also be represented by the length of a black line. The area within the 200E mark may be recessed or flat.

[0065] Figures 32 to 39 illustrate examples of scales including marks. As shown in Figure 32, the clasp 35F has the 200F scale represented by a white dot. Specifically, the size of the dot increases as the length of the band 100 is adjusted to be longer. Note that it is not limited to white dots; it may also be represented by black circular dots. The area within the frame of the 200F scale may be recessed or flat.

[0066] As shown in Figure 33, the clasp 35G represents the 200G mark by the number of dots. Specifically, the number of dots increases as the length of the band 100 is adjusted to be longer. The dots increase in the shape of an isosceles triangle. In other words, the dots increase radially.

[0067] As shown in Figure 34, the clasp 35H represents the 200H marking with the number of dots. Specifically, the number of dots increases as the length of the band 100 is adjusted to be longer. The dots increase in a right-angled triangular shape, with the base following the edges of rails 20 and 21.

[0068] As shown in Figure 35, the clasp 35I has its scale 200I represented by a wave-like shape. Specifically, the number of waves increases as the length of the band 100 is adjusted to be longer. The peaks of the waves have a rounded, arc-like shape.

[0069] As shown in Figure 36, the clasp 35J is represented by a wave-like shape at the 200J mark. Specifically, the number of waves increases as the length of the band 100 is adjusted to be longer. The peaks of the waves have a sharp angle.

[0070] As shown in Figure 37, the clasp 35K is represented by a wave shape with a series of concave sections at the 200K mark. Specifically, the number of waves increases as the length of the band 100 is adjusted to be longer.

[0071] As shown in Figure 38, the clasp 35L has a scale 200L represented by bird footprints. Specifically, as the length of the band 100 is adjusted to be longer, the bird footprints formed alternately on rails 20 and 21 are indicated by the indicator unit 300.

[0072] As shown in Figure 39, the clasp 35M represents the 200M mark using varying line thickness. Specifically, the line thickness increases as the length of the band 100 is adjusted to be longer. The area within the 200M mark may be recessed or flat.

[0073] As shown in Figure 40, the central clasp 35N has the 200N markings represented by rectangular gemstones. Each of the four 200N markings formed on rails 20 and 21 has a gemstone of the same size embedded in it. Note that it is not limited to gemstones; the markings may also be represented by white outlines or black lines.

[0074] As shown in Figure 41, the clasp 35P has the scale 200P represented by a rhombus-shaped gemstone. Each of the four scales 200P formed on rails 20 and 21 has a gemstone of the same size embedded in it. Note that it is not limited to gemstones; it may also be represented by a white rhombus shape or a black rhombus shape mark.

[0075] As shown in Figure 42, the clasp 35Q has the scale 200Q represented by a round gemstone. Each of the four scales 200Q formed on rails 20 and 21 has a gemstone of the same size embedded in it. Note that it is not limited to gemstones; it may also be represented by a white-outlined circle or a black-filled circle.

[0076] Figures 43 to 52 illustrate examples of scales that include recesses and protrusions. Recesses and protrusions are formed by cutting or other methods. As shown in Figures 43 and 44, the clasp 35R has the scale 200R represented by a V-groove shape. Similarly, the indicator display section 300R of the pressing case 74 also has a V-groove shape extending from the rail 20 side to the rail 21 side. In other words, when the indicator display section 300R points to any of the scale 200R, the scale 200R and the indicator display section 300R are connected in a straight line by the V-groove shape. The V-groove is formed, for example, by diamond cutting. By forming it with diamond cutting, the V-groove can be made to shine brightly.

[0077] As shown in Figures 45 and 46, the scale 200S on the central stopper 35S is represented by a convex shape. Similarly, the indicator display section 300S on the pressing case 74 is also represented by a convex shape extending from the rail 20 side to the rail 21 side. In other words, when the indicator display section 300S points to any of the scale 200S, the scale 200S and the indicator display section 300S are connected in a straight line by a convex shape.

[0078] As shown in Figures 47 and 48, the central stopper 35T has the scale 200T represented in a concave shape. Similarly, the indicator display section 300T of the pressing case 74 also has a concave shape extending from the rail 20 side to the rail 21 side. In other words, when the indicator display section 300T indicates any of the scale 200T, the scale 200T and the indicator display section 300T are connected in a straight line with a concave shape.

[0079] As shown in Figure 49, the clasp 35U has a scale 200U represented by grooves and flat sections. Specifically, as the length of the band 100 is adjusted to be longer, the shape of the scale 200U changes from a deep groove to a shallow groove to a flat section. In addition, alphabetical characters are formed on the cover member 30 to supplement and indicate the scale 200U. A indicates the end of a deep groove. B indicates the boundary between a deep groove and a shallow groove. C indicates the end of a shallow groove. D indicates a flat section. Note that the alphabetical characters are not required to be formed.

[0080] As shown in Figure 50, the clasp 35V represents the 200V scale with a groove, a flat section, and a convex section. Specifically, as the length of the band 100 is adjusted to be longer, the shape of the 200V scale changes from a groove, a flat section, to a convex section. In addition, alphabetical characters are formed on the cover member 30 to supplement and indicate the 200V scale. A indicates the end of the groove. B indicates the boundary between the groove and the flat section. C indicates the boundary between the flat section and the convex section. D indicates the end of the convex section. Note that the alphabetical characters are not required to be formed.

[0081] As shown in Figures 51 and 52, the central stopper 35W has a scale of 200W represented by a concave shape with an incline, specifically a stepped shape. Specifically, the highest point of the incline functions as the scale of 200W.

[0082] As shown in Figure 53, the clasp 35X represents the 200X scale as a spreading line mark. Specifically, the 200X scale is shaped like a right triangle, which is divided into three sections. As the length of the band 100 is adjusted to be longer, the spreading of the line of the 200X scale increases. The area within the 200X scale frame may be recessed or flat.

[0083] As described above, the band 100 of this embodiment comprises a first band 10 attached to one end of the watch body 1, a second band 15 attached to the other end of the watch body 1, and a clasp 35 connecting the first band 10 and the second band 15. The clasp 35 comprises a cover member 30, a plurality of engaging portions located on the back side of the cover member 30 at a position fixed to the cover member 30, and a movable member connected to the first band 10 and having an engaging pin 27 that can selectively engage with any of the plurality of engaging portions, and which is movable relative to the cover member 30. The clasp 35 is provided with a scale 200 that indicates the positions where the plurality of engaging portions and the engaging pin 27 engage, as viewed from the back side of the cover member 30 in plan view.

[0084] With this configuration, the clasp 35 is provided with a scale 200 that indicates the position where the engaging portion and the engaging pin 27 engage. Therefore, when the user adjusts the length of the band 100, they can easily determine which position the engaging pin 27 is engaged with. Thus, the length of the band 100 can be easily adjusted.

[0085] Furthermore, in the band 100 of this embodiment, the clasp 35 is preferably positioned on the back side of the cover member 30 and has rails 20, 21 arranged along the longitudinal direction of the cover member 30, with a plurality of engaging portions and scales 200 formed on the rails 20, 21. With this configuration, since the grooves 29 and scales 200 are formed on the same rails 20, 21, misalignment between the grooves 29 and scales 200 can be eliminated.

[0086] Furthermore, in the band 100 of this embodiment, it is preferable that the scale 200 includes either lines, marks, or numbers. With this configuration, since the scale 200 is made up of lines or marks, it can be processed relatively easily, for example, by laser processing.

[0087] Furthermore, in the band 100 of this embodiment, it is preferable that the scale 200 includes recesses, i.e., V-grooves, concave grooves, or protrusions. With this configuration, since it includes recesses and protrusions, it becomes possible to see the scale 200 in three dimensions, which improves aesthetics.

[0088] Furthermore, in the band 100 of this embodiment, it is preferable that the scale 200 be provided at a position corresponding to the end of the movable member. With this configuration, since the scale 200 is provided at a position corresponding to the end of the movable member, it is possible to indicate the movement on the end face of the movable member without providing an indicator or display part at the end of the movable member. Therefore, there is no need for unnecessary patterns, and aesthetics can be improved.

[0089] Furthermore, in the band 100 of this embodiment, it is preferable that the movable member is provided with an indicator display unit 300 that indicates the scale 200. With this configuration, since the movable member is provided with an indicator display unit 300, it becomes possible to adjust the indicator display unit 300 in correspondence with the scale 200, making it easy to understand by visual inspection.

[0090] Furthermore, in the band 100 of this embodiment, it is preferable that the indicator display section 300 includes either a line or a mark. With this configuration, since the indicator display section 300 is made of a line or a mark, it can be processed relatively easily, for example, by laser processing. Also, the indicated position is easy to understand.

[0091] Furthermore, in the band 100 of this embodiment, it is preferable that the indicator display section 300 includes recesses or protrusions, i.e., V-grooves, concave shapes, or convex shapes. With this configuration, since it includes recesses and protrusions, it becomes possible to see a three-dimensional indicator display section 300, thereby improving aesthetics. In particular, matching the design with the scale 200 can further improve aesthetics.

[0092] Furthermore, in the band 100 of this embodiment, it is preferable that the indicator display section 300 is provided at the end of the movable member. With this configuration, since the indicator display section 300 is provided at the end of the movable member, the indicated position is easy to understand. In particular, the aesthetics can be further improved by matching the design with the scale 200.

[0093] Furthermore, the watch 150 of this embodiment includes the band 100 described above. With this configuration, since it includes the band 100 described above, it is possible to provide a watch 150 in which the length of the band 100 can be easily adjusted.

[0094] The following describes some variations of the embodiments described above.

[0095] As described above, the method is not limited to providing scales 200A to 200X on the clasps 35A to 35X, i.e., the fine-adjustment clasps. For example, scale 200Y may be provided on the cover member 30, as shown in clasp 35Y in Figures 54 and 55. Furthermore, the method is not limited to providing the indicator display section 300 on the pressing case 74. The indicator display section 300 may also be provided on the first band 10. Additionally, the length of the band 100 may be adjusted using a dedicated adjustment jig, as shown in clasp 35Y in Figures 54 and 55.

[0096] The clasp 35Y in Figures 54 and 55 will be described in detail. Components identical to those in the above-described embodiment will be given the same numbers and their descriptions will be omitted. The clasp 35Y connects the first band 10Y and the second band 15 (not shown, see Figure 1), and comprises a cover member 30Y, a middle plate 31, and a bottom plate 32.

[0097] The first band 10Y includes multiple pieces 2 and connecting pieces 11Y that connect to the ends of the pieces 2, and is connected to the cover member 30Y via the connecting pieces 11Y. The connecting piece 11Y is connected to the pieces 2 at one end via a connecting pin and to the cover member 30Y at the other end via a spring bar. The other end of the connecting piece 11Y is provided with a through hole through which the spring bar passes. The connecting piece 11Y is also provided with a notch that exposes the end of the spring bar when it is passed through the through hole. In this modified example, the connecting piece 11Y functions as a movable member and the spring bar functions as an engaging part.

[0098] The cover member 30Y has multiple pairs of recesses on the inner side of opposite side walls of the cover member 30Y, which engage with both ends of the spring bar, along the longitudinal direction of the first band 10Y. These multiple pairs of recesses function as engaged parts.

[0099] In this modified example, as described above, a scale 200Y is provided on the back surface of the cover member 30. Additionally, an indicator section 300 is provided on the connecting piece 11Y. When a spring bar is inserted through the connecting piece 11Y and both ends of the spring bar engage with a pair of recesses, the clasp 35Y and the first band 10Y are connected. In this state, by inserting a special adjustment jig into the notch of the connecting piece 11Y and compressing the spring bar, the first band 10, along with the connecting piece 11Y, can be removed from the cover member. Then, by selecting a pair of recesses and engaging the spring bar, the connecting piece 11Y and the cover member can be engaged at the desired position. In this way, the length of the first band 10Y is adjusted.

[0100] As described above, the instruction display section 300 is not limited to being provided at the end of the movable member, specifically the end of the pressing case 74 that constitutes the movable member; the instruction display section 300 may be omitted. Alternatively, the instruction display section 300 may be omitted, and only the end may be polished to a mirror finish to make the end stand out, thus serving as a substitute for the instruction display section 300.

[0101] As described above, the scale 200 with its irregularities is not limited to having the depth and height shown in the figure, but may be changed to any desired depth and height. [Explanation of Symbols]
