[0031] Embodiments of an electronic watch and an electronic watch body according to the present invention will be described with reference to the accompanying drawings. The following embodiments are subject to various technically preferred limitations for implementing the present invention, but the scope of the present invention is not limited to the following embodiments and the illustrated examples. Furthermore, in the following embodiments, the electronic watch will be referred to simply as a "watch."

[0032] like Figure 1 and Figure 14 As shown in the figures, the watch of the present embodiment includes an electronic watch body (hereinafter referred to as simply "watch body 1") and an external component that can be installed on the watch body 1. In the embodiment, the external component is either a first component or a second component that is selectively installed on the watch body 1. The first component is a bezel 3 on which a watch band 5 can be installed, and the second component is an outer shell 7. The bezel 3 and the outer shell 7 are freely removable relative to the watch body 1. Hereinafter, the state in which the bezel 3 is installed on the watch body 1 will be described as "watch 100" of the first embodiment, and the state in which the outer shell 7 is installed on the watch body 1 will be described as "watch 200" of the second embodiment. In addition, the structure of the watch body 1 of the first embodiment and the second embodiment is the same. Therefore, first, the watch body 1 will be described as a structure common to the first embodiment and the second embodiment.

[0033] The watch body 1 in the embodiment includes a body case 11 housing a watch module (not shown) and a back cover 12 mounted on the back side of the body case 11. The body case 11 is formed of various synthetic resins, and the back cover 12 is formed of various metals such as stainless steel (SUS).

[0034] In an embodiment, Figure 2As shown in FIG. 1 , the outer shape of the watch body 1 is formed into a substantially rectangular shape when viewed from above. The watch body 1 has a plurality of protrusions protruding toward the outer side. The vertices of the protruding sides of the protrusions constitute the outermost shape Es of the watch body 1. Figure 2 In FIG, the outermost shape Es of the watch body 1 is indicated by a dotted line. Figure 2 As shown, the watch body 1 of the embodiment is substantially symmetrical in both its top and bottom shapes and its left and right shapes. Furthermore, the shape of the outermost shape Es and the length dimensions of the corresponding side faces are substantially identical at the 6 o'clock and 12 o'clock, and 3 o'clock and 9 o'clock sides of the analog watch. Therefore, the watch body 1 maintains a substantially identical shape regardless of whether it is rotated 90 degrees or 180 degrees.

[0035] The watch module housed in the main body housing 11 includes various components (not shown) required for the watch function, such as a display unit that displays information such as time, a driver that drives the display unit, and a circuit unit that controls them. In this embodiment, the display unit includes a display panel 13 exposed on the surface side of the watch body 1 (see FIG. Figure 1 ) to display various information such as the time, date, and day of the week on the display panel 13. The display panel 13 may be, for example, a liquid crystal display (LCD), an organic electroluminescent display, or other flat panel display. Furthermore, the display unit is not limited to a display panel 13 that digitally displays the time, etc. For example, it may be an analog display unit with pointers and a dial, or a so-called combined type display unit capable of both analog and digital displays.

[0036] An operating unit 14 is provided on the outer side of the main body housing 11. The operating unit 14 is a portion where the user inputs various operations, such as buttons and a crown. Figure 1 and Figure 2 In the example of the embodiment of the present invention, two operating parts 14 are provided on each of the two side surfaces of the pointer type watch at 3 o'clock and 9 o'clock. The operating part 14 is a second protrusion provided on the watch body 1. The operating part 14 extends outward from the outer part of the watch body 1 at 3 o'clock and 9 o'clock. Figure 2 As shown by the dotted lines, the vertices of the extended side constitute the outermost shape Es on the 3 o'clock side and the 9 o'clock side of the watch body 1.

[0037] In addition, if Figure 2 As shown, the back cover 12 is attached to the main body case 11 by screwing it onto two opposing sides of the watch body 1. The portion where the main body case 11 and back cover 12 are screwed together is provided with screw hole spaces 16 each containing screw bosses with screw holes (not shown). In this embodiment, the back cover 12 is secured to the six o'clock and twelve o'clock sides of the analog watch by two screws 15, respectively. That is, the portion where the back cover 12 is screwed (the screw hole spaces 16) is located on a side different from the side where the operating unit 14 is located.

[0038] Furthermore, the back cover 12 is fixed with screws, avoiding the watch module housed in the main body case 11. Therefore, the screw hole spaces 16 are provided outside the space for housing the watch module and are formed as a plurality of protrusions on the outer periphery of the watch body 1. The screw hole spaces 16 as protrusions extend toward the outer sides of the 6 o'clock and 12 o'clock sides of the watch body 1, as shown in FIG. Figure 2 As shown by the dotted lines, the vertices of the extended side constitute the outermost shape Es on the 6 o'clock side and the 12 o'clock side of the watch body 1.

[0039] Between the adjacent screw hole spaces 16 among the plurality of screw hole spaces 16 as the protruding portion, a first protrusion 17 is formed by covering the screw hole spaces 16 in a manner of connecting the screw hole spaces 16. The first protrusion 17 is provided in a range that does not protrude outward compared to the apex of the protruding side of the connected screw hole spaces 16 (i.e., inside the outermost shape Es of the watch body 1). In the embodiment, Figure 2 , etc., show an example in which the first protrusion 17 is formed so that adjacent screw hole spaces 16 (protrusions) on the same side are connected in a substantially coplanar manner. This allows the outermost shape Es of the watch body 1 to have a shape with fewer irregularities and excellent design. Furthermore, the shape of the first protrusion 17 is not limited to the illustrated example; for example, it may be recessed further inward than the line connecting adjacent screw hole spaces 16 (protrusions).

[0040] Furthermore, in the watch 100 of the embodiment, as described later, when the watch band 5 is attached, it is positioned so as to pass through the back side of the watch body 1 (the side provided with the back cover 12). The screws 15 securing the back cover 12 are positioned along the path through which the watch band 5 passes when attached. Since the screws 15 are located on the back side of the watch body 1 and are formed from various metals such as stainless steel (SUS), if the watch band 5 comes into contact with the screws 15 (particularly the screw heads), the front side of the watch band 5 may be rubbed or damaged.

[0041] In this regard, in the watch body 1 of the embodiment, a protective protrusion 18 is provided on the back side of the first protrusion 17 (the back side of the watch body 1) and near the screw 15, which protrudes from the top (screw head) of the screw 15 (see FIG. Figure 2 、 Figure 4 、 Figure 10 ). How much the protective protrusion 18 protrudes from the top of the screw 15 (screw head) is a matter of appropriate setting. In addition, if the protective protrusion 18 protrudes too much, the protective protrusion 18 will hinder the passage of the watch band 5 when the watch band 5 is installed. Therefore, for example, Figure 8 As shown, the protection protrusion 18 protrudes beyond the apex of the screw 15 , but preferably does not protrude below the surface on the back side of the back cover 12 .

[0042] In addition, Figure 2 In the figures, the protective protrusion 18 is shown as a quadrangular prism that is generally rectangular when viewed from above. However, the shape of the protective protrusion 18 is not limited to the illustrated example. For example, the protective protrusion 18 may also be a cylindrical shape that is circular or elliptical when viewed from above. Furthermore, the corners of the protective protrusion 18 that faces the watchband 5 are preferably chamfered or rounded to prevent the watchband 5 from getting caught on its surface.

[0043] [First embodiment]

[0044] In the first embodiment, the exterior component (first part) constituting the watch 100 is the bezel 3 mounted on the watch body 1. The bezel 3 has a first opening formed at least on one end. The band 5 is inserted through the first opening. When the band 5 is inserted through the first opening, the band 5 is positioned on the back side (the side that is not visible when the band is worn on the arm). Figure 10 On the side surface 35a opposite to the lower side (the lower side in the middle), there is a first protrusion 36 protruding into the first opening. In this embodiment, the bezel 3 is attached to the watch body 1 in a manner that surrounds the outer circumference of the watch body 1. Figure 1 、 Figure 3 The bezel 3 of this embodiment will be described in detail.

[0045] like Figure 1 and Figure 3 As shown, the bezel 3 of the embodiment has a frame-shaped portion 31, a side portion 32, and an extension portion 34. When the frame-shaped portion 31 is mounted on the watch body 1, it is arranged on the surface side of the watch body 1. In addition, the side portion 32 extends downward from the frame-shaped portion 31 and is arranged on the side of the watch body 1 when mounted on the watch body 1. The extension portion 34 is a portion that extends downward from the back of the watch body 1 (the back cover 12 in the embodiment) when the bezel 3 is mounted on the watch body 1. In this embodiment, as shown in FIG. Figure 4 and Figure 5 As shown in FIG. 1 and FIG. 2 , when the bezel 3 is mounted on the watch body 1 , a pair of extension portions 34 are provided at positions facing each other across the watch body 1 .

[0046] In an embodiment, Figure 1 As shown, the bezel 3 is attached from the surface side of the watch body 1, with the extension 34 provided on one side of the side of the watch body 1 where the first protrusion 17 is provided. Specifically, in this embodiment, the extensions 34 are positioned at the 6 o'clock and 12 o'clock positions of the analog watch when attached to the watch body 1. The bezel 3 is formed from a polyurethane resin, such as polyurethane (PUR). Furthermore, the bezel 3 is preferably formed from a synthetic resin such as polyurethane resin, which is generally flexible and allows at least the extension 34 to be elastically deformable. However, the material forming the bezel 3 is not limited to this.

[0047] When the bezel 3 is mounted on the watch body 1, the frame-shaped portion 31 exposes at least a portion of the display panel 13 of the watch body 1 within the frame, allowing visual recognition of various displays such as the time. Furthermore, engagement holes 33 are formed on the side surface 32 at positions corresponding to the operating portion 14 of the watch body 1 when the bezel 3 is mounted on the watch body 1. In the embodiment, the engagement holes 33 are through-holes into which the operating portion 14, which serves as the second protrusion, is inserted. When the bezel 3 is mounted on the watch body 1, the operating portion 14 is fitted into the engagement holes 33. Furthermore, when the bezel 3 is mounted on the watch body 1, the operating portion 14 is exposed from the engagement holes 33, and the operating portion 14 can be operated from the outside with the bezel 3 mounted.

[0048] A pair of openings 35 are formed in each of the pair of extensions 34. The openings 35 provided on one extension 34 are referred to as first openings, and the openings 35 provided on the other extension 34 are referred to as second openings. The openings 35 are portions through which the watch band 5 is inserted when the watch band 5 is installed, and have a width that is equal to or greater than the width of the watch band 5. Furthermore, when the bezel 3 is installed on the watch body 1, the openings 35 only need to be provided at positions opposite to the watch body 1. For example, when the side surface 32 extends downward from the back of the watch body 1 and faces each other, the openings may be formed at positions opposite to each other on the side surface 32.

[0049] A protrusion 36 (first protrusion) is provided on the side surface 35a of the opening 35 that faces the back side of the watch band 5 when the watch band 5 is inserted through the opening 35. Furthermore, the bezel 3 has a first protrusion provided on at least one end of the first opening. However, in this embodiment, the first and second openings are provided at opposing positions across the watch body 1, and each opening 35 has a protrusion 36 (first and second protrusions) that protrudes into the opening 35 (the first and second openings). Alternatively, the protrusion 36 may be provided on only one of the pair of openings 35 (the first and second openings).

[0050] As described later, the strap 5 inserted into the opening portion 35 has a first planar portion on the back side, namely the second portion 52, and a second planar portion protruding from the second portion 52 (the first planar portion on the back side), namely the first portion 51. That is, the first portion 51 as the second planar portion and the second portion 52 as the first planar portion have different heights in the thickness direction, and the first portion 51 protrudes further toward the back side than the second portion 52, and the height in the thickness direction becomes higher. As described later, the boundary portion between the second portion 52 as the first planar portion and the first portion 51 as the second planar portion becomes a step portion 53. In the embodiment, the first portion 51 has a thickness that is sufficient to eventually pass through the setting portion of the protrusion 36 of the bezel 3 or a thickness greater than this thickness (first thickness). However, the protrusion 36 is elastically deformable, and when the strap 5 is inserted into the opening portion 35, if the first portion 51 is stuck, the protrusion 36 is able to deform while moving along the insertion direction X (refer to Figure 6A The watch band 5 is allowed to pass through by tilting the watch band 5 while the protrusion 36 is tilted. Furthermore, when the protrusion 36 is positioned in the second portion 52, it returns to its original shape and engages with the step 53 that forms the boundary between the first portion 51 and the second portion 52. Furthermore, it is preferable that the front end of the protrusion 36 be chamfered or rounded on the upstream side in the insertion direction X of the watch band 5 to facilitate insertion of the watch band 5. Furthermore, it is preferable that the protrusion 36 have a slight angle (inclination) toward the insertion direction X of the watch band 5.

[0051] Furthermore, on the bezel 3, when the bezel 3 is mounted on the watch body 1, a component side locking portion that is locked with the first protrusion 17 is provided at a position corresponding to the first protrusion 17. In this embodiment, the component side locking portion is the first engaging portion 37. Figure 3 As shown in FIG. 3 , the first engaging portion 37 is an inner side surface of a pair of extension portions 34 and is respectively disposed above the opening portion 35. Figure 9 As shown in FIG. 1 , the first engaging portion 37 is a claw or protrusion having a hook shape or a shape similar to a hook protruding toward the inner side of the bezel 3, and when the bezel 3 is mounted on the watch body 1 in a manner surrounding the outer periphery of the watch body 1, the first engaging portion 37 is provided with a hook shape or a protrusion having a hook shape. Figure 1 The lower side and the back side in the middle are configured to abut against the first protrusion 17.

[0052] Thus, in this embodiment, the bezel 3, serving as the first component, includes a first engaging portion 37, serving as a component-side locking portion, provided at a position corresponding to the first protrusion 17, and an engaging hole 33, serving as a second protrusion, provided at a position corresponding to the operating portion 14. When the bezel 3 is mounted on the watch body 1, the first engaging portion 37 engages with the first protrusion 17, and the operating portion 14 fits into the engaging hole 33, thereby securing the bezel 3 to the watch body 1.

[0053] Furthermore, in the first embodiment, by attaching the watch band 5 to the bezel 3 attached to the watch body 1, the watch 100 can be attached to the wrist Wr (in addition, Figure 13 In FIG, the double-dashed line indicates that the watch on the wrist (Wr) functions. Figure 6A As shown, the watch band 5 includes a watch band body 50, a buckle 55 provided on one end of the watch band body 50, and a pin 56. Furthermore, a loop 57 is attached to the side of the watch band body 50 where the buckle 55 and the like are provided. The loop 57 is passed through the other end of the watch band 5 when the watch band 5 is worn on the wrist Wr.

[0054] The band body 50 is formed into a long, flexible strip from various relatively soft synthetic resins, such as polyurethane (PUR), silicone resin, and fluororubber. The center of the band body 50 in the width direction is recessed relative to the peripheral edges, forming a sweat trap 50a. This prevents or reduces the band 5 from sticking to the skin when worn on a wrist Wr or the like.

[0055] like Figure 6A 、 Figure 6B As shown in FIG. 1 , the band body 50 has a first portion 51 of a first thickness at a substantially central portion in the longitudinal direction L, and has second portions 52 of a smaller thickness (thinner) than the first portion 51 on both sides of the first portion 51 in the longitudinal direction L. Furthermore, the boundary between the first portion 51 and the second portion 52 forms a step portion 53. When the bezel 3 is mounted on the watch body 1, the band 5 is inserted from the insertion-side end portion 50b of the band body 50 into a pair of openings 35 formed in the bezel 3 at positions opposite to each other across the watch body 1 (see FIG. 1 ). Figure 6B 、 Figure 11 ),like 7A to 7C As shown, it is configured so as to pass through the back side of the watch body 1.

[0056] Furthermore, the band body 50 has a concave-convex portion 50c (for example, see FIG. 5 ) on the back side thereof to improve the design and to facilitate the band 5 to be worn along the wrist Wr or the like. Figure 7C (see the portion surrounded by the dotted line in the figure). However, in such a concave-convex portion 50c, the rising angle from the reference surface (the surface of the band body 50) becomes gentler than that of the step portion 53, making it easier to pull the band 5 into the opening 35 and less likely to get caught. In addition, the band body 50 has portions that extend appropriately toward the front side and portions that extend appropriately toward the back side, but the thickness of the band body 50 is generally uniform as a whole. This makes it easy to pull the band 5 when putting it on and taking it off through the opening 35 of the bezel 3. In addition, by making the thickness of the entire band generally uniform, it is also easy to operate when applying surface printing for decoration, etc. to the band 5.

[0057] In the embodiment, the insertion side end portion 50b is formed into a tapered shape with thickness becoming thinner and width becoming narrower toward the front end. As a result, the band 5 (band body 50) can be inserted into the opening 35 more smoothly. Figure 6B 、 Figure 11 and Figure 12 In the embodiment, the direction of inserting the band 5 into the opening 35 of the bezel 3 is indicated as the insertion direction X. In the state where the first portion 51 is arranged on the back side of the watch body 1 ( Figure 12 In the state shown in FIG, the protrusion 36 protruding into the opening 35 of the bezel 3 engages with the step 53 of the band 5. As a result, the band 5 is held on the bezel 3. Moreover, by inserting the band 5 to the back side of the watch body 1 in this way, the watch body 1 is sandwiched between the bezel 3 and the band 5 (see FIG. Figure 7B 、 Figure 7C 、 Figure 12 ), the engagement state of the watch body 1 and the bezel 3 is more firmly maintained, and the watch body 1 can be reliably prevented from falling off from the bezel 3.

[0058] Next, refer to Figures 10 to 13 The function of the electronic watch 100 as the first embodiment will be described. In the first embodiment, when the bezel 3 as the first component is mounted on the watch body 1, as shown in FIG. Figure 1 As shown, the bezel 3 is covered from the surface of the watch body 1 and arranged within the frame-shaped portion 31 so that at least a portion of the display panel 13 is exposed. Furthermore, while the bezel 3 is slightly unfolded, the operating portions 14 provided on the 3 o'clock and 9 o'clock sides of the watch body 1 are respectively engaged with the engaging holes 33 of the bezel 3, so that the protruding ends (button heads) are operable and exposed from the engaging holes 33. Furthermore, the bezel 3 is locked to the watch body 1 by engaging the first engaging portions 37, which serve as the component-side locking portions, with the first protrusions 17 provided on the 6 o'clock and 12 o'clock sides of the watch body 1.

[0059] When the bezel 3 is locked on the watch body 1, Figure 6B As shown, the band body 50 of the band 5 is inserted into the opening 35 of the bezel 3 from the side where the buckle 55 or the pin 56 of the band 5 is arranged in the watch 100 (the 12 o'clock side in the embodiment of the pointer type watch). Figure 11 As shown, the extension portion 34 (at least the protrusion 36 provided on the extension portion 34) is elastically deformable, and when the watch band 5 is inserted into the opening portion 35, the watch band 5 is passed while being tilted in an appropriate insertion direction X. The watch band 5 is pulled to a position corresponding to the back surface of the watch body 1 at the first portion 51. When the protrusion 36 is arranged at the second portion 52 having a smaller thickness than the first portion 51, as shown in FIG. Figure 12 As shown, the protrusion 36 returns to its original shape and engages with the step portion 53 .

[0060] In addition, in this embodiment, if Figure 10 As shown, the protrusion 36 fits within the perspiration-wicking portion 50a, which is recessed relative to the peripheral edge of the cross-sectional shape of the band body 50. Therefore, the perspiration-wicking portion 50a acts as a guide, allowing the band body 50 to be pulled straight in the insertion direction X. Furthermore, while the band 5 is pulled to the opening 35 with the front surface of the band body 50 facing the back surface of the watch body 1, protective protrusions 18 are provided near the screws 15 exposed on the back surface of the watch body 1. This prevents the surface of the band body 50 from interfering with the screws 15 and causing damage.

[0061] like Figure 13 As shown, in order to wear the watch 100 with the watch band 5 attached on the wrist Wr of the user, the watch band 5 is wound around the wrist Wr, the pin 56 is locked in the small hole 58 corresponding to the thickness of the user's wrist, and the pin is passed through the buckle 55. Then, the remaining end of the watch band body 50 (the end on the insertion side end 50b side) is passed through the free ring 57 and locked. When the watch band 5 is worn on the wrist Wr while being inserted through the opening 35, the two ends of the watch band 5 are extended in the direction of the wrist Wr ( Figure 13 As a result, the second portion 52 with a relatively small thickness is deformed in a manner along the wrist Wr, and the extension portion 34 having the opening 35 is provided to extend inward ( Figure 13 The watch 100 is elastically deformed by bending (toward the side indicated by the arrow in the middle, toward the watch body 1), and the protrusion 36 of the opening 35 is pressed against the step 53 while the extension 34 is bent. As a result, the watch 100 of this embodiment can be worn on a wrist Wr or other wearer, and the band 5 is securely fixed to the bezel 3, more reliably preventing it from falling off. Furthermore, in this state, the watch body 1 is also securely fixed between the band 5 and the bezel 3.

[0062] To remove the bezel 3 from the watch body 1, first, remove the watch band 5 from the opening 35 of the extension 34 of the bezel 3. While the watch band 5 is removed from the wrist Wr, the bezel 3 can be removed by pulling it out in the direction opposite to the insertion direction X. Once the watch band 5 is removed, the extensions 34 of the bezel 3 are pushed apart in the separating direction (outwards toward the 6 o'clock and 12 o'clock sides). This removes the first engaging portion 37, which serves as the component-side locking portion provided on each extension 34, from the underside of the first protrusion 17 of the watch body 1, releasing the engagement. Furthermore, the side surfaces 32 of the bezel 3 are also pushed apart in the separating direction (outwards toward the 3 o'clock and 9 o'clock sides), removing the operating portion 14 inserted into the engaging hole 33 and releasing the engagement. This allows the watch band 5 and bezel 3 to be removed from the watch body 1.

[0063] In this way, the watch 100 of this embodiment can easily attach and detach the bezel 3 to the watch body 1. For example, the bezel 3 can be replaced with another one of different color, material, shape, etc., or the watch band 5 attached to the bezel 3 can be replaced. In addition, components other than the bezel 3 (such as the outer shell case 7 shown in the second embodiment) can also be attached to the watch body 1.

[0064] Next, the effects of the electronic timepiece 100 and the watch body 1 according to the first embodiment will be described. The electronic timepiece 100 according to this embodiment includes a watch body 1 and a bezel 3 as an external component attached to the watch body 1 and capable of retaining a watch band 5. The bezel 3 has an opening 35 (first opening) formed at one end. The opening 35 has a protrusion 36 (first protrusion) on a side surface 35a opposite the back surface of the watch band 5 inserted through the opening 35, protruding into the opening 35. The watch band 5 has a second back surface portion 52, which is a first flat portion on the back surface, and a first portion 51, which is a second flat portion protruding from the second back surface portion 52. The boundary between the first portion 51 and the second portion 52 is a step 53. When the watch band 5 is inserted into the opening 35 of the bezel 3, the step 53 engages with the protrusion 36, thereby retaining the watch band 5 on the bezel 3 and, consequently, on the watch body 1 to which the bezel 3 is attached.

[0065] Thus, in this embodiment, by attaching the watch band 5 to the bezel 3 attached to the watch body 1, the watch body 1 is sandwiched between the watch band 5 and the bezel 3 and secured, making it difficult for the watch 100 to fall off when worn on the wrist Wr. Furthermore, the watch band 5 engages only with the protrusion 36 of the bezel 3 and can be easily removed by removing the portion hooked on the protrusion 36 (the step 53 in this embodiment). Therefore, the user can easily attach and detach the watch band 5 to the watch body 1 and easily replace the watch band 5.

[0066] Furthermore, in the embodiment, the bezel 3 (at least the protrusion 36 of the bezel 3 ) is elastically deformable. When the watch band 5 is inserted into the opening 35, the band 5 passes through while being tilted down in the insertion direction X. The band 5 then returns to its original shape in the thin second portion 52 and engages with the step 53 that forms the boundary with the first portion 51. Therefore, when the band 5 is pulled into the opening 35, there is little hooking resistance, allowing for smooth pulling. Furthermore, the elastic deformation of the protrusion 36 allows the band 5 to be securely engaged with the step 53. This allows for easy attachment and detachment of the band 5 without user pressure.

[0067] Furthermore, as described above, the bezel 3 of the embodiment is detachable from the watch body 1, making it easy to replace it with another bezel 3 of a different color, material, shape, etc., or to replace the watch band 5 attached to the bezel 3. Furthermore, various outer cases other than the bezel 3 can also be easily attached.

[0068] Furthermore, the bezel 3 of this embodiment has a pair of extensions 34 extending downward from the back of the watch body 1 at opposing positions across the watch body 1 when attached to the watch body 1. A pair of openings 35 are formed in each of the extensions 34. This eliminates the need for a strap attachment portion on the watch body 1, even when the watch body 1 is intended to be used as a wristwatch with a strap, allowing for a more compact watch body 1. Furthermore, by pulling the strap 5 through the pair of openings 35, the watch body 1 can be held from the back, further reliably preventing the watch body 1 from falling off the bezel 3.

[0069] Furthermore, the extension portion 34 of the embodiment elastically deforms, stretching and flexing toward the wrist Wr, etc., when the watchband 5, inserted through the opening 35, is worn on the intended wrist Wr, etc. Furthermore, the protrusion 36 of the opening 35 presses against the step 53 while the extension 34 is flexed. Consequently, when the watchband 5 is attached to the wrist Wr, etc., the watch body 1, bezel 3, and watchband 5 are more securely integrated, making it difficult for the watchband 5 or watch body 1 to fall off the bezel 3.

[0070] The watch body 1 of the embodiment has a first engaging portion 37 at a position corresponding to the first protrusion 17 when the bezel 3 is attached. The bezel 3 is locked to the watch body 1 by engaging the first engaging portion 37 with the first protrusion 17. Furthermore, the watch body 1 of the embodiment has an operating portion 14 as a second protrusion in addition to the first protrusion 17, and the bezel 3, as a first component, has an engaging hole 33 provided at a position corresponding to the operating portion 14. When the bezel 3 is attached to the watch body 1, the first engaging portion 37 engages with the first protrusion 17, and the operating portion 14 fits into the engaging hole 33, thereby locking the bezel 3 to the watch body 1. Therefore, compared to a case where the bezel 3 is locked solely by the engagement of the first engaging portion 37 with the first protrusion 17, it can be locked to the watch body 1 with a higher locking force.

[0071] Furthermore, the engagement hole 33 is a through-hole into which the operating portion 14 is inserted. When the bezel 3 is attached to the watch body 1, the operating portion 14 is exposed through the engagement hole 33. Therefore, the user can operate the operating portion 14 of the watch body 1 while the bezel 3 is attached. Furthermore, because the operating portion 14 is locked within the through-hole, sufficient locking force is achieved to secure the bezel 3 to the watch body 1 simply by inserting the operating portion 14 into the engagement hole 33.

[0072] Furthermore, in particular, the watch body 1 of this embodiment is formed into a generally rectangular shape when viewed from above, with the first protrusions 17 provided on two opposing side surfaces of the watch body 1 (the 6 o'clock and 12 o'clock sides), and the operating portion 14, serving as the second protrusion, provided on the 3 o'clock and 9 o'clock sides of the watch, which are different from the sides provided with the first protrusions 17. Therefore, by engaging the first engaging portion 37 with the first protrusion 17 and fitting the operating portion 14 into the engaging hole 33, the watch body 1 can be secured on three or more sides, enabling the bezel 3 to be more stably secured to the watch body 1.

[0073] Furthermore, the back cover 12 is screwed to the back of the watch body 1. The screws 15 securing the back cover 12 are positioned along the path through which the watch band 5 passes when inserted into the opening 35 of the bezel 3. However, a protective protrusion 18, projecting beyond the screw head, is provided near the screws 15. This prevents the surface of the watch band 5 from interfering with and being damaged by the screws 15. Furthermore, in the embodiment, the protrusion 36 is provided on the side surface 35a of the opening 35 that faces the back of the watch band 5 and protrudes into the opening 35, roughly forming a positional relationship with the protective protrusion 18 provided on the back of the watch body 1, thereby holding the watch band 5 from both sides. Therefore, in conjunction with the engagement between the protrusion 36 and the step 53, the protective protrusion 18 also prevents the watch band 5 from shifting or falling off, potentially securing the watch band 5 more securely.

[0074] [Second embodiment]

[0075] In the second embodiment, a watch 200 is composed of a watch body 1 and an outer case 7. The shape and structure of the watch body 1 are the same as those described above, so their description will be omitted. The outer case 7 of the watch 200 is a housing attached to the watch body 1 so as to surround the outer circumference of the watch body 1. It is a second component that is selectively attached to the watch body 1, along with the bezel 3, which serves as the first component described in the first embodiment.

[0076] like Figure 14 As shown in FIG. 1 , the outer shell case 7 of this embodiment is formed on the outer side of the substantially circular shell body 71 ( FIG. 1 ) in a plan view. Figure 14 A locking portion 73 having a locking hole 731 is formed protruding from the outer portion of the upper side of the middle portion. Figure 18 As shown, the retaining hole 731 extends through the back of the watch, forming a through hole that can be hooked, passed through a ring or carabiner, various straps or ropes, etc. The outer shell 7 is formed of, for example, silicone rubber with relatively high rubber hardness (hard). In the embodiment, the outer shell 7 is a transparent or translucent component, and the internal structure can be observed from the outside. In addition, the material forming the outer shell 7 is not limited to the materials shown here.

[0077] The housing case 7 of the embodiment is open at the front and back. Figure 14 and Figure 15 As shown in FIG. 1 , the opening 72 on the surface side is formed to be approximately the same size as or slightly smaller than the display panel 13 of the watch body 1. When the outer shell 7 is mounted on the watch body 1, at least a portion of the display panel 13 of the watch body 1 is exposed, making it possible to visually recognize various displays such as the time. Figure 16 and Figure 17 As shown in FIG. 1 , the opening 75 on the back side of the outer shell 7 is formed to a size that allows the watch body 1 to be taken out and put in. Figure 15 and Figure 16 As shown in FIG. 1 , a back cover 74 is attached to the opening 75 on the back side, thereby closing the opening. When the back cover 74 is attached, a portion of the inner periphery of the opening 75 is hooked onto the back cover 74. The portion hooked onto the back cover 74 is formed into a hook shape, securing the back cover 74. The back cover 74 is formed, for example, from a transparent acrylic plate, and the components housed therein can be viewed from the outside.

[0078] A storage portion 76 for storing the watch body 1 is provided in the outer shell 7. Figure 17 As shown in FIG. 1 , the storage portion 76 is formed to be substantially along the outermost shape Es of the watch body 1 (see FIG. Figure 2 ) size and shape. For example, Figure 17 As shown, the corresponding inner wall surface of the storage portion 76 abuts against the side surfaces of the watch body 1 at the 1 o'clock-2 o'clock side, the 4 o'clock-5 o'clock side, the 7 o'clock-8 o'clock side, and the 10 o'clock-11 o'clock side. As a result, the watch body 1 arranged in the storage portion 76 can be positioned to suppress deviation and shaking. In addition, for example Figure 17 As shown, a space is ensured at the 3 o'clock and 9 o'clock sides of the watch body 1 where the operating portion 14 is provided so as not to contact the inner wall surface of the storage portion 76, so that the operating portion 14 will not be accidentally pressed when subjected to vibration or the like.

[0079] Furthermore, the outer shell case 7 as the second component has a second engaging portion 77 as a component side engaging portion that is engaged with the first protrusion 17 when mounted on the watch body 1. Figure 17 and Figure 18 As shown, the second engaging portions 77, which serve as component-side locking portions, are provided in the housing portion 76 at positions corresponding to the first protrusions 17 of the watch body 1. The second engaging portions 77 are a pair of tongue-shaped components that extend inward from the inner wall of the housing portion 76, corresponding to the 6 o'clock and 12 o'clock positions of the watch body 1 housed in the housing portion 76. When the watch body 1 is housed in the housing portion 76, the second engaging portions 77 abut against the first protrusions 17 from the back side (the side of the back cover 12 of the watch body 1) and engage with the first protrusions 17. In this embodiment, the outer shell 7 is locked to the watch body 1 by engaging the second engaging portions 77 with the first protrusions 17.

[0080] Furthermore, in the first embodiment, when the bezel 3 is mounted on the watch body 1, the first engaging portion 37 engages with the first protrusion 17, and the operating portion 14 is engaged with the engaging hole 33, thereby securing the bezel 3 to the watch body 1. However, in this embodiment, when the outer case 7 is mounted on the watch body 1, unlike the first embodiment, the outer case 7 is secured to the watch body 1 solely by the engagement of the second engaging portion 77 with the first protrusion 17. Therefore, to securely fix the outer case 7 to the watch body 1, it is preferable that the retaining force exerted by the second engaging portion 77 on the watch body 1 is greater than that exerted by the first engaging portion 37. Therefore, the second engaging portion 77 is formed thicker than the first engaging portion 37. Furthermore, the outer case 7 is made of, for example, a relatively hard material such as silicone rubber and has greater rigidity than the bezel 3. Therefore, the engagement of the second engaging portion 77 with the first protrusion 17 alone can sufficiently secure the watch body 1.

[0081] Furthermore, in the watch body 1 of this embodiment, as described above, the first protrusion 17 is formed by connecting adjacent screw hole spaces 16 of the plurality of screw hole spaces 16 serving as the protrusion so that they are substantially coplanar. Consequently, the outermost shape Es of the watch body 1 is relatively straight with minimal irregularities, and the outer case 7 is formed of a transparent or translucent material. This ensures a high level of design and allows for an enjoyable appearance even when the watch body 1 is viewed from the outside.

[0082] Furthermore, even when the watch body 1 is housed in the storage portion 76, a slight gap is maintained on the back side of the outer case 7 between the watch body 1 and the back cover 74 that closes the opening 75, allowing for the placement of photos or various items within this gap. In this embodiment, since the back cover 74 is transparent, even when photos are placed within, the photos can be viewed from the outside through the back cover 74, allowing the back side of the outer case 7 to be customized to the user's preferences. Furthermore, it is also possible to enjoy the logo, etc., on the back cover 12 of the watch body 1, rather than placing photos on the back side of the outer case 7.

[0083] Next, the operation of the electronic timepiece 200 according to the second embodiment will be described. In the second embodiment, when the outer shell case 7 as the second component is mounted on the watch body 1, as shown in FIG. Figure 15 、 Figure 17 As shown in FIG. 1 , the watch body 1 is housed in the housing portion 76 through the opening 75 on the back side of the outer case 7. At this time, the first protrusions 17 provided on the 6 o'clock and 12 o'clock sides of the watch body 1 pass over the second engaging portions 77 serving as the component-side locking portions, fit into the predetermined positions of the housing portion 76, and are housed in the housing portion 76 in a manner that is slightly pressed in.

[0084] Thus, when the watch body 1 is stored in a predetermined position in the storage portion 76, the pair of second engaging portions 77 are brought into contact with the first protrusion 17 from the back side (see FIG. Figure 18 ), the outer shell 7 and the watch body 1 are locked by the engagement of the second locking portion 77 with the first protrusion 17. In addition, outside the portion where the operating unit 14 is stored, the inner wall of the storage portion 76 abuts against the outer periphery of the watch body 1 to prevent the watch body 1 from shifting or shaking. Then, the back cover 74 is inserted into the opening 75 on the back side of the outer shell 7 to close the opening 75. The watch is thus completed. In this state, if, for example, a buckle is installed on the locking portion 73, the watch 200 can be installed on a bag or the like with the watch body 1 stored therein and carried around.

[0085] When removing the outer shell 7 from the watch body 1, first remove the back cover 74 from the opening 75 on the back side of the outer shell 7, so that the upper and lower sides of the outer shell 7 (on the left and right sides) where the second engaging portion 77 is provided are aligned. Figure 14 The parts of the watch body (corresponding to the 6 o'clock and 12 o'clock sides, which are housed in the upper and lower parts and the interior) are warped toward the front surface of the outer case 7. At this point, the watch body 1 can be pushed out from the front surface of the outer case to the back surface. Thus, when the second engaging portion 77 disengages from the first protrusion 17 and the engagement is released, the watch body 1 can be removed from the outer case 7. Furthermore, the user can attach the bezel 3, the first component, to the watch body 1 to wear it on their wrist Wr, or enjoy the outer case in a different color or shape.

[0086] Next, the effects of the electronic watch 200 and the watch body according to the second embodiment will be described. In this embodiment, the watch 200 includes components such as the bezel 3 shown in the first embodiment, in addition to the outer case 7, which are attachable and detachable. The bezel 3 and outer case 7 can also be selectively attached to the watch body 1. Therefore, simply by changing the attachment components, the watch body 1 can be used not only as a wristwatch worn on the wrist Wr, but also through various variations such as with decorative accessories such as a strap.

[0087] Furthermore, as described above, the watch body 1 protrudes toward the outer side, and the vertex of the protruding side has the outermost shape Es (see FIG. 1 ) constituting the watch body 1. Figure 2 ) are formed on the plurality of protruding portions of the screw hole spaces 16, and adjacent screw hole spaces 16 are connected to form a substantially coplanar surface. Therefore, the outermost shape Es of the watch body 1 is relatively straight with few irregularities, and even when the outer shell case 7 is formed of a transparent or translucent material, the watch body 1 has a high design quality and can be visually observed from the outside.

[0088] Furthermore, in the watch body 1 of this embodiment, when the bezel 3 (first component) and the outer case 7 (second component) are mounted on the watch body 1, the first protrusion 17, which engages the component-side engaging portions (first engaging portion 37 and second engaging portion 77), is formed so as not to protrude outward beyond the apex on the projecting side of the connecting screw hole space 16. Thus, a structure for mounting the bezel 3 or the outer case 7 on the watch body 1 can be achieved without changing the outermost shape Es of the watch body 1 (without increasing the size of the watch body 1).

[0089] Furthermore, the outer case 7, serving as the second component of this embodiment, is provided with a housing portion 76 for accommodating the watch body 1. A second engaging portion 77, serving as a component-side locking portion, is provided at a position on the housing portion 76 corresponding to the first protrusion 17. Therefore, when the outer case 7 is mounted on the watch body 1, the watch body 1 can be simply positioned by simply accommodating it within the housing portion 76. Furthermore, the first protrusion 17 can also be locked to the second engaging portion 77.

[0090] In addition, the above describes the embodiment of the present invention, but the present invention is not limited to this embodiment, and various modifications are possible without departing from the scope of the main purpose. For example, in this embodiment, the case where the watch body 1 is roughly rectangular when viewed from above is illustrated, but the watch body 1 constituting the watch 100, 200 as the electronic watch of the present invention is not limited to a rectangle. For example, it can also be roughly circular when viewed from above or roughly elliptical when viewed from above. In this case, it is preferred that at least the first protrusion is provided at the opposite position of the watch body 1. Thus, at least at the position of the first protrusion, the watch body 1 can be fixed to the first component or the second component in a balanced manner, thereby forming a structure that is difficult to fall off.

[0091] Furthermore, for example, in this embodiment, the engaging hole 33 provided on the bezel 3 as the first component is a through hole into which the operating portion 14 as the second protrusion is inserted, but the engaging hole is not limited to a through hole. For example, it may be a cutout portion hooked on a part of the operating portion 14. In this case, although the same locking force as in the case of a through hole cannot be expected, for example, if the locking force is provided from the surface side (the surface side of the watch, Figure 1 If the shape of the engagement hole 33 (ie, the upper side) covers the operating portion 14, the operating portion 14 can be locked from the front side, and the first protrusion 17 can be locked from the back side using the first engagement portion 37, thereby pressing the watch body 1 from the front and back, thereby preventing looseness and positional displacement. In addition, compared to the case where the engagement hole 33 is a through hole, the case where the bezel 3 is a cutout portion makes it easier to remove the bezel 3 from the watch body 1.

[0092] Furthermore, the watch body 1 does not need to be provided with the second protrusions protruding toward the 3 o'clock and 9 o'clock sides of the watch. In other words, the watch body 1 may also be configured without the operating portion 14 protruding toward the outside. In this case, the bezel 3 does not need to be provided with the engaging hole 33. In this case, the bezel 3 is simply secured to the watch body 1 by the engagement of the first protrusion 17 with the first engaging portion 37. However, even in this case, when the watch band 5 is attached, the watch band 5 is positioned on the back side of the watch body 1, and the watch body 1 is clamped from the front and back by the bezel 3 and the watch band 5, thereby preventing accidental detachment.

[0093] Furthermore, for example, in this embodiment, the watch body 1 is stored in the storage portion 76 of the outer case 7, serving as the second component, with the 12 o'clock side facing upward. However, if the four sides of the watch body 1 are substantially the same shape, as in this embodiment, the watch body 1 can also be stored in the storage portion 76 in a different orientation (e.g., reverse or horizontal). For example, when the watch body 1 is placed in the outer case 7 for use, it can be stored in the storage portion in the opposite orientation (with the 12 o'clock side facing downward), allowing the display to be viewed from the opposite direction, as in a pocket watch. Furthermore, when stored horizontally, the second engaging portion 77 is positioned between the two operating portions 14 located on the same side. However, in this embodiment, by providing a gap between the two operating portions 14 that is comparable to the gap between the protective protrusions 18 on the first protrusion 17, the second engaging portion 77 can be secured between the operating portions 14, avoiding the position of the operating portions 14.

[0094] In addition, this embodiment illustrates a case where the outer shell 7 as the second component has a substantially circular shape when viewed from above. However, the shape of the outer shell 7 is not limited to the illustrated example and may be, for example, a substantially elliptical shape when viewed from above or a substantially rectangular shape when viewed from above. Furthermore, the outer shell 7 may also have a shape that imitates the appearance of various characters or animals.

[0095] In addition, the watch body 1 of the watch 100, 200 constituting the electronic watch of the present invention widely includes devices with a time display function, such as various electronic devices such as smart watches and sports watches, as well as wearable devices that obtain biological information such as heart rate or blood flow other than time, and can be widely used.
