Summary of the Invention

Problems to be Solved by the Invention

[0004] However, the bezel described in Patent Document 1 is arranged to surround the outer periphery of a cover member (referred to as a "clock glass" in Patent Document 1) of the clock, and the outermost exterior on the visual side of the clock is the cover member. Since the cover member is formed of glass or the like, when it is arranged on the outermost exterior of the clock, there is a problem that the cover member is likely to crack or get damaged when the clock drops or the like. The present invention is for improving and solving the problems in such a situation, and provides a clock capable of absorbing an impact by an exterior member when the clock drops or the like.

Means for Solving the Problems

[0005] To solve the aforementioned problems, the present invention provides a watch having a case body, comprising: a cylindrical case body oriented in a first direction; and a ring-shaped first exterior member positioned on one side of the case body in the first direction, wherein the ring-shaped first exterior member comprises a ring member and first projections extending a predetermined length from a plurality of locations along the circumferential direction of the ring member toward the center of the ring member, and the first projections of the first exterior member are located on the outermost part of the watch. [Effects of the Invention]

[0006] According to the present invention, when a watch is dropped, the exterior material can absorb the impact, thus providing an effect. [Brief explanation of the drawing]

[Modes for carrying out the invention]

[0008] An embodiment of the clock according to the present invention will be described with reference to Figures 1 to 7. In this embodiment, the clock is a wristwatch worn on the wrist (hereinafter simply referred to as "clock 100"). In the following, the "first direction" of the clock refers to the height direction (thickness direction) of clock 100, which is the up and down direction in Figures 1 and 2. Also, the "12 o'clock direction," "6 o'clock direction," "3 o'clock direction," and "9 o'clock direction" in Figures 1 to 3 refer to the respective directions in the display of an analog clock. Although the embodiments described below are subject to 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] The clock 100 comprises a case body 1 and a first exterior member 2. As shown in Figure 1, the case body 1 is a cylindrical member oriented in the vertical direction, which is the "first direction," and is formed from a metal material such as stainless steel (SUS), titanium, or aluminum. It is preferable that the case body 1 has a certain degree of strength, but the material constituting the case body 1 is not limited to those exemplified here. The case body 1 may be formed from, for example, various synthetic resins. In the illustrated example, the case body 1 and the clock 100 equipped therewith are shown to be substantially circular in plan view, but the shape of the case body 1 and the clock 100 is not limited to a circular shape, and may be elliptical, rectangular, or the like. In this embodiment, the case body 1 is formed in the shape of a short, hollow column with openings at the top and bottom. The case body 1 is provided with support parts 11 at the 12 o'clock and 6 o'clock positions in the analog clock, which support the first part 51 and the second part 52, which will be described later. Furthermore, as shown in Figures 1 to 4, operation buttons 12 are attached to the outer circumferential surface of the case body 1 as appropriate, and through holes 13 are formed at the attachment points of the operation buttons 12, penetrating into the interior of the case body 1, through which the shaft portion 121 of the operation button 12 is inserted. The number and arrangement of the operation buttons 12 are not particularly limited, but in this embodiment, as shown in Figures 1 and 3, operation buttons 12 are provided at approximately four locations on the clock 100: the "2 o'clock position," the "4 o'clock position," the "8 o'clock position," and the "10 o'clock position."

[0010] Furthermore, screw-fastening portions 14 are formed on the outer circumferential surface of the case body 1 at the "3 o'clock position" and the "9 o'clock position" of the watch 100. In this embodiment, the screw-fastening portions 14 are protrusions that project outward from the outer circumferential surface of the case body 1, as shown in Figures 1 and 6. The screw-fastening portions 14 are the parts to which the first exterior member 2 and the second exterior member 5, described later, are fastened with screws 15. Specifically, the screw-fastening portions 14 are shaped to engage with the second projection 23 of the first exterior member 2 and the first part 51 of the second exterior member 5. Also, a screw hole 141 is formed approximately in the center of the screw-fastening portion 14, extending from the outside in the direction of protrusion of the screw-fastening portion 14 toward the inside (towards the case body 1). In this embodiment, the second projection 23 of the first exterior member 2 and the first part 51 of the second exterior member 5 are locked to the screw fastening part 14, and then the second part 52 of the second exterior member 5 is positioned and a screw 15 is inserted through the screw hole 141 to secure it. This allows the first exterior member 2 and the second exterior member 5 to be fastened together to the case body 1.

[0011] Furthermore, locking projections 16 for engaging the first exterior member 2 are provided on the outer circumferential surface of the case body 1 at locations different from those where the screw-fastening parts 14 are provided. The number and placement of the screw-fastening parts 14 and locking projections 16 are not particularly limited, but in order to more securely fix the first exterior member 2, it is preferable that the screw-fastening parts 14 and locking projections 16 are arranged as evenly as possible in the circumferential direction of the case body 1. In this embodiment, as shown in Figure 1, an example is given in which locking projections 16 are provided at the "12 o'clock position" and the "6 o'clock position" of the clock 100. As a result, the first exterior member 2 can be fixed to the case body 1 at four locations provided at approximately equal intervals by the screw-fastening parts 14 provided at the "3 o'clock position" and the "9 o'clock position" of the clock 100 and the locking projections 16 provided at the "12 o'clock position" and the "6 o'clock position" of the clock 100.

[0012] The opening on the front side of the case body 1 (the side visible in the watch), which is one side in the vertical direction, is closed by a cover member 3. The cover member 3 is a transparent crystal member formed from, for example, glass or transparent resin material. The shape of the cover member 3 is not particularly limited, but in this embodiment, the cover member 3 is roughly spherical with a raised central portion (see Figures 1 and 6). As shown in Figure 1, in this embodiment, a trim member 4 is placed in the opening on the front side of the case body 1, and the cover member 3 is attached to the opening of the case body 1 via the trim member 4. Note that the trim member 4 is not an essential component. The opening on the back side of the case body 1 (the side not visible in the watch, the bottom side in Figure 1) is closed by a back cover member 8. The back cover member 8 may be formed integrally with the case body 1.

[0013] The hollow portion inside the case body 1 constitutes a storage space for various components. Module 7 is located in the hollow portion inside the case body 1. Module 7 is a functional part that operates the clock 100, and includes, for example, a circuit board and various electronic components (not shown). Note that detailed illustration of module 7 is omitted in Figures 1, etc. (In Figures 5, 6, and 7, module 7 is shown with a dashed line). A dial 6 is superimposed on the upper side of module 7 (the front side of the clock, the viewing side) inside the case body 1. A through hole 61 is formed in the center of the dial 6, and a pointer shaft 71 protruding from the module 7 side is inserted through the through hole 61. At least one pointer 62 is supported on the free end side of the pointer shaft 71 (the upper end side in the height direction of the clock 100). Figure 1 illustrates the case where three pointers 62 are supported by the pointer shaft 71. The three pointers 62 are, for example, an hour hand, a minute hand, and a second hand. Note that the pointers 62 are not limited to these. In all figures except Figure 1, the illustration of guideline 62 has been omitted.

[0014] The first exterior member 2 is a ring-shaped member positioned on one side of the case body 1 in the vertical direction, which is the "first direction". In this embodiment, the vertical side is the surface side of the case body 1 (the side visible in the watch, the upper side in Figures 1 and 2), and is the same side on which the cover member 3 is positioned. In this embodiment, the cover member 3 is positioned between the ring-shaped first exterior member 2 and the case body 1. The first exterior member 2 is made of, for example, various synthetic resins. The ring-shaped first exterior member 2 has a ring member 21 and first projections 22 that protrude from multiple locations along the circumferential direction of the ring member 21 toward the center of the ring member 21 by a predetermined length. In this embodiment, the first projections 22 function as hour markers when the time is displayed by the hands 62. It is preferable that four or more first projections 22 are provided in order to fully fulfill their role as indicators and to protect the cover member 3. The illustrated example illustrates a case in which 12 first protrusions 22 are provided at approximately equal intervals along the circumferential direction of the ring member 21, from the 12 o'clock position to the 11 o'clock position on the clock 100. However, the number and arrangement of the first protrusions 22 are not limited to the illustrated example. For example, the first protrusions 22 may be provided at four locations on the clock 100, such as the "12 o'clock position," "6 o'clock position," "3 o'clock position," and "9 o'clock position."

[0015] In the assembled state, the first projection 22 of the first exterior member 2 is positioned to straddle the cover member 3 from the ring member 21 side when the first exterior member 2 is viewed from the "first direction" above. That is, the first projection 22 extends from the base end side fixed to the ring member 21 toward the center of the ring member 21 to the top of the cover member 3, protruding along the surface of the cover member 3. Therefore, in the clock 100 according to this embodiment, the first exterior member 2 (the first projection 22 of the first exterior member 2) constitutes the outermost outer layer on the surface side (upper side) of the clock 100. In other words, in the clock 100 of this embodiment, the first projection 22 of the first exterior member 2 is located on the outermost side of the clock 100. The extent to which the first projection 22 extends over the cover member 3 can be appropriately set, taking into consideration the design, etc. However, as mentioned above, since the first projection 22 has the function of an hour marker, it is preferable that it does not cover the hands 62. Specifically, it is preferable that the protrusion of the first projection 22 is such that it may overlap with a portion of the minute hand (e.g., the second hand or minute hand) that extends to near the outer edge of the dial 6, but does not overlap with the hour hand (e.g., the hour hand). As mentioned above, the cover member 3 in the embodiment has a spherical shape with a raised central portion, and the first projection 22 has an arc-shaped curve in a side view to conform to the surface shape of the cover member 3. The shape of the cover member 3 is not limited to the illustrated example, and if the surface of the cover member 3 is flat, the first projection 22 will also have a straight shape without curving. Note that in Figures 5 and 7, the cover member 3 is omitted from the illustration in order to clearly show the shape of the first projection 22.

[0016] In addition, the ring-shaped first exterior member 2 of the embodiment has a second protrusion 23 that protrudes toward the other side in the first direction (i.e., the back side of the case body 1, the lower side in FIGS. 1 and 2). The second protrusion 23 is a portion that is screwed and fixed to the cylindrical case body 1 together with a second exterior member 5 (the first part 51 and the second part 52 of the second exterior member 5) described later. At a position corresponding to the screw fixing portion 14 of the case body 1, it has a through hole 231 having a diameter through which the screw fixing portion 14 can be inserted. By inserting the screw fixing portion 14 into the through hole 231, the first exterior member 2 is locked to the case body 1. Then, at the screw fixing portion 14, in addition to the first exterior member 2, the first part 51 and the second part 52 of the second exterior member 5 are overlapped, and a screw 15 is inserted into the screw hole 141 of the screw fixing portion 14, so that in addition to the first exterior member 2, the first part 51 and the second part 52 of the second exterior member 5 are clamped together and fixed to the case body 1.

[0017] Furthermore, the ring-shaped first exterior member 2 in the embodiment has a third protrusion 25 that protrudes toward the other side in the first direction (i.e., the back side of the case body 1, the lower side in FIGS. 1 and 2). The third protrusion 25 is locked to the locking convex portion 16 of the case body 1, and has a through hole 251 at a position corresponding to the locking convex portion 16. By inserting the locking convex portion 16 into the through hole 251, the first exterior member 2 is locked to the case body 1. As described above, the case body 1 of the embodiment is provided with screw fixing portions 14 at the "3 o'clock position" and the "9 o'clock position" of the clock 100, and locking convex portions 16 are provided at positions corresponding to the "12 o'clock position" and the "6 o'clock position" of the clock 100, which are positions shifted by 45 degrees from this. Thereby, the locations where the first exterior member 2 is locked to the case body 1 are arranged at substantially equal intervals along the circumferential direction of the case body 1, and the first exterior member 2 can be more stably locked to the case body 1. In addition, the screw fixing portion 14 and the locking convex portion 16 can easily position the first exterior member 2 in the circumferential direction, and can also prevent displacement and rotation in the circumferential direction.

[0018] Further, the clock 100 includes a second exterior member 5 disposed on the outer peripheral side of the cylindrical case body 1. In the embodiment, the second exterior member 5 includes a first part 51 provided on one side of the outer peripheral side surface of the cylindrical case body 1 (the "12 o'clock side" in the clock 100 in FIG. 1 etc.) and a second part 52 provided on the other side of the outer peripheral side surface of the cylindrical case body 1 (the "6 o'clock side" in the clock 100 in FIG. 1 etc.). In the embodiment, the first part 51 is integrally provided with a first band member 53 disposed on one side of the outer peripheral side surface of the case body 1 (the "12 o'clock side" in the illustrated example), and the second part 52 is integrally provided with a second band member 54 disposed on the other side of the outer peripheral side surface of the case body 1 (the "6 o'clock side" in the illustrated example). Although not shown, the clock 100 can be worn on the user's wrist or the like by connecting the free ends of the first band member 53 and the second band member 54 to each other. In the embodiment, the second exterior member 5 is formed of a resin such as urethane. Note that the material forming the second exterior member 5 is not limited to this.

[0019] Of the second exterior member 5, the first part 51 has a locking portion 511 that engages with the screw-fastening portion 14 of the case body 1. In this embodiment, the locking portions 511 are provided at positions corresponding to the "3 o'clock position" and the "9 o'clock position" of the clock 100 when assembled. Each locking portion 511 has a through hole 511a formed at a position corresponding to the screw-fastening portion 14, with a diameter that allows the screw-fastening portion 14 to be inserted. Furthermore, of the second exterior member 5, the second part 52 has locking portions 521 at positions corresponding to the "3 o'clock position" and the "9 o'clock position" of the clock 100 when assembled, corresponding to the screw-fastening portion 14 of the case body 1. Each locking portion 521 has a through hole 521a formed at a position corresponding to the screw hole 141 of the screw-fastening portion 14. In the assembled state, the first exterior member 2 and the second exterior member 5 are fixed to the outer circumferential surface of the cylindrical case body 1 with screws. At the screw fastening points (the areas where the screws are fastened, indicated by the dashed lines in Figure 6 as "screw fastening points 150"), the three layers of the locking portion 511 of the first part 51 and the locking portion 521 of the second part 52 constituting the second exterior member 5, and the second projection 23 of the first exterior member 2 are superimposed.

[0020] Furthermore, in the first part 51 and second part 52 of the second exterior member 5, recessed and convex fitting portions 55 corresponding to the shape of the upper surface of the first exterior member 2 are formed in the parts that are arranged to surround the first exterior member 2 in the assembled state. In the assembled state, the recessed and convex fitting portions 55 correspond to the parts of the first exterior member 2 that correspond to the first projection 22, and the convex parts correspond to the parts where there is no first projection 22, and are placed on the upper surface (upper surface in Figure 1, etc.) of the ring member 21 of the first exterior member 2 so as to avoid the first projection 22. By overlapping the recessed and convex fitting portions 55 with at least a part of the ring member 21 in this way, the first exterior member 2 is reliably prevented from coming off upwards.

[0021] Next, the operation of the clock 100 according to this embodiment will be described. When assembling the clock 100 according to this embodiment, the module 7 and the dial 6 are placed inside the case body 1, and the pointer 62 is attached to the free end of the pointer shaft 71 that protrudes upward from the through hole 61 of the dial 6. In addition, a trim member 4 is placed on the upper side of the case body 1, and a cover member 3 is attached to close the upper opening of the case body 1. Furthermore, the lower opening of the case body 1 is closed with a back cover member 8.

[0022] Next, the first exterior member 2 is attached from the top of the cover member 3. At this time, the screw fixing portion 14 provided on the outer surface of the case body 1 is inserted through the through hole 231 of the second projection 23. Furthermore, the locking projection 16 provided on the outer surface of the case body 1 is inserted through the through hole 251 of the third projection 25 of the first exterior member 2. As a result, the first exterior member 2 is positioned relative to the case body 1 in its circumferential direction and is locked in a state where it cannot rotate around its circumference. In this state, the first projection 22 of the first exterior member 2, which protrudes from the ring member 21 side toward the center, is placed so as to straddle the cover member 3 from the ring member 21 side. In addition, each of the first projections 22 is positioned as an hour marker from the 12 o'clock position to the 11 o'clock position on the watch.

[0023] Furthermore, the first part 51 of the second exterior member 5, to which the first band member 53 is integrally attached, is attached to the clock 100 from the 12 o'clock side, and the second part 52 of the second exterior member 5, to which the second band member 54 is integrally attached, is attached to the clock 100 from the 6 o'clock side. At this time, the locking part 511 of the first part 51 is locked to the screw-fastening part 14 to which the second projection 23 of the first exterior member 2 is locked, so as to overlap the second projection 23. Specifically, the screw-fastening part 14 is inserted through the through hole 511a of the locking part 511. Then, the locking portion 521 of the second part 52 is positioned so as to overlap the second projection 23 and the locking portion 511 of the first exterior member 2 with the screw-fastened fixing portion 14 to which the second projection 23 and the locking portion 511 of the first part 51 are locked. A screw 15 is then inserted from the outside through the through hole 521a of the locking portion 521, and the locking portion 521 is fixed to the screw hole 141 of the screw-fastened fixing portion 14 of the case body 1 with the screw 15.

[0024] As a result, at the "screw fastening points 150" shown in Figure 6, the first exterior member 2 and the second exterior member 5 (the first part 51 and the second part 52 of the second exterior member 5) are fastened together to the case body 1 with screws 15. When attaching the first part 51 and the second part 52, the positions of the interlocking parts 55 are adjusted so that they fit together with the shape of the upper surface of the first exterior member 2, and the interlocking parts 55 press down on at least a part of the ring member 21 of the first exterior member 2 from above. As a result, once the first exterior member 2 and the second exterior member 5 are fixed to the case body 1, the first exterior member 2 cannot be removed upwards. Furthermore, the operation buttons 12 are attached to the outside of the second exterior member 5 at four locations on the clock 100: the "2 o'clock position," the "4 o'clock position," the "8 o'clock position," and the "10 o'clock position." This completes the clock 100.

[0025] In this type of clock 100, the outermost part on the top side is the second projection 23 of the first exterior member 2. Therefore, even if the clock 100 is dropped from the top side (surface side), the second projection 23 of the first exterior member 2 will first come into contact with the floor or other surface, absorbing the impact, and the cover member 3 will not be directly hit. As a result, the cover member 3, which is made of glass or the like, is less likely to break or get scratched, and the appearance of the clock 100 is maintained.

[0026] As described above, in this embodiment, the watch 100 comprises a cylindrical case body 1 oriented in a first direction (up and down in this embodiment), and a ring-shaped first exterior member 2 positioned on one side of the case body 1 in the first direction (upper side in this embodiment, the side where the watch is viewed). The ring-shaped first exterior member 2 has a ring member 21 and first projections 22 that protrude from multiple locations along the circumferential direction of the ring member 21 toward the center of the ring member 21 by a predetermined length, with the first projections 22 of the first exterior member 2 being located on the outermost part of the watch 100. As a result, the first projections 22 of the first exterior member 2 become the outermost part of the watch 100 on the upper side (viewing side), and even if the watch 100 falls from above (viewing side), the first projections 22 of the first exterior member 2 will first hit the floor or the like and absorb the impact. For example, even if a cover member 3 made of glass or the like is provided on the viewing side of the watch 100, preventing direct impact to the cover member 3 makes it less likely to break or get scratched, thus maintaining the appearance of the watch 100.

[0027] Furthermore, in this embodiment, the first projection is a time marker. Therefore, the shock-absorbing effect of the clock 100 can be provided to a component that is almost certainly present in any analog clock.

[0028] Furthermore, in this embodiment, the case body 1 is provided with a cover member 3 positioned between the ring-shaped first exterior member 2 and the case body 1 on one side in the first direction (the upper side in this embodiment, the side where the watch is viewed). The first projection 22 of the ring-shaped first exterior member 2 is positioned to straddle the cover member 3 from the ring member 21 side when the ring-shaped first exterior member 2 is viewed from the first direction. As a result, the first projection 22 of the first exterior member 2 is positioned above the cover member 3, becoming the outermost outer layer on the upper (viewing side) of the watch 100. Therefore, even if the watch 100 is dropped from above (viewing side), the first projection 22 will first hit the floor or other surface and absorb the impact, preventing the cover member 3 from cracking or getting damaged.

[0029] Furthermore, in this embodiment, the first projection 22 protrudes along the surface of the cover member 3. For example, if the surface of the cover member 3 is spherical as in this embodiment, the first projection 22 is formed in an arc shape along it, so that when an external impact is applied, the first projection 22 makes contact with the cover member 3 over a surface area, preventing the impact from being concentrated on a single point on the cover member 3.

[0030] Furthermore, in this embodiment, the clock 100 includes a second exterior member 5 positioned on at least a portion of the outer circumference of the cylindrical case body 1, and the first exterior member 2 and the second exterior member 5 are fastened together to the cylindrical case body 1 with screws 15. Therefore, one fixing point can be done with a single screw 15, reducing the number of parts and the amount of work required.

[0031] Furthermore, the ring-shaped first exterior member 2 of the embodiment has a second projection 23 that protrudes to the other side in the first direction (downward in the embodiment, the non-visible side of the watch), and the second projection 23 is fixed to the cylindrical case body 1 with screws together with the second exterior member 5. This makes it possible to fix the components together with screws 15 while positioning them at the second projection 23.

[0032] Furthermore, in this embodiment, the second exterior member 5 includes a first part 51 provided on one side of the outer peripheral surface of the cylindrical case body 1 and a second part 52 provided on the other side of the outer peripheral surface of the cylindrical case body 1. The first exterior member 2 and the second exterior member 5 are fixed to the outer peripheral surface of the cylindrical case body 1 with screws, and in the area where they are fixed with screws ("screw fixing location 150" in Figure 6), the three layers of the first part 51 and the second part 52 constituting the second exterior member 5 and the first exterior member 2 are superimposed. As a result, the three members can be fixed at one location with a single screw 15, reducing the number of parts and the amount of work required.

[0033] Furthermore, in this embodiment, the first part 51 is integrally provided with a first band member 53 positioned on one side of the outer peripheral surface of the cylindrical case body 1, and the second part 52 is integrally provided with a second band member 54 positioned on one side of the outer peripheral surface of the cylindrical case body 1. This makes it possible to fix the bands (first band member 53, second band member 54) simply and efficiently.

[0034] 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 various modifications are possible without departing from the spirit of the invention.

[0035] For example, in the above embodiment, the second exterior member is shown to include a first part 51 and a second part 52, with a first band member 53 integrally provided on the first part 51 and a second band member 54 integrally provided on the second part 52. However, the second exterior member is not limited to those exemplified in the embodiment, as long as it is arranged on at least a part of the outer circumference of the cylindrical case body 1. For example, as in the watch 200 shown in Figure 8, the second exterior member may be a first bezel member 56 attached to the 12 o'clock side of the watch 200 and a second bezel member 57 attached to the 6 o'clock side of the watch 200, and may be composed separately from the band. In this case as well, the first exterior member 2 and the second exterior members, the first bezel member 56 and the second bezel member 57, are fastened together to the cylindrical case body 1 with screws 15. In other words, at the "screw fastening point 150" (see Figure 6), the screws are fastened with three layers overlapping: the second projection 23 of the first exterior member 2, and the locking portions (not shown) of the first bezel member 56 and the second bezel member 57, which are the second exterior members.

[0036] Furthermore, as shown in Figure 9, for example, the watch 300 may have a second exterior component that is a substantially ring-shaped bezel member 58, which is separate from the band. In this case as well, the first exterior component 2 and the second exterior component, the bezel member 58, are fastened together to the cylindrical case body 1 with screws 15, but at the "screw fastening location 150" (see Figure 6), the screws are fastened with two layers superimposed: the second projection 23 of the first exterior component 2 and the locking portion (not shown) of the second exterior component, the bezel member 58. Note that in both the watch 200 shown in Figure 8 and the watch 300 shown in Figure 9, the configuration other than the second exterior component is the same as that shown in the embodiment.

[0037] Furthermore, in the above embodiment, the example given was that the clock 100 is an analog clock equipped with a pointer 62 that displays the time by the pointer 62. However, the clock is not limited to an analog type. For example, it may have a liquid crystal display and display the time digitally, or it may be a hybrid clock equipped with both analog and digital display units. If the clock displays the time digitally, the first projection of the first exterior member 2 does not need to function as an hour marker and may extend further toward the center of the clock toward the cover member 3 than shown in the illustrated example. In this case, an even greater protective effect on the cover member 3 can be expected.

[0038] Furthermore, in the above embodiment, the case in which the watch 100 is equipped with a cover member 3 and the first projection 22 of the first exterior member 2 protrudes from the outer circumference of the case body 1 toward the center to protect the cover member 3 was described. However, it is not essential that the watch 100 is equipped with a cover member 3. The watch 100 only needs to be equipped with a first projection 22 that protrudes from the outer circumference of the case body 1 toward the center, and for example, the first projection 22 may be provided so as to protrude over the dial 6. In this case, by having the first projection 22 protrude so as to span from the outer circumference toward the center, it is possible to prevent damage to the dial 6 and the various parts of the module 7 located beneath the dial 6.

[0039] Furthermore, watches are not limited to those that only have a timekeeping function; they may also have various functions such as a pedometer, heart rate monitor, altimeter, barometer, etc., or they may be so-called smartwatches.

[0040] 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]
