DETAILED DESCRIPTION OF THE INVENTION

[0011] (First embodiment) Next, the first embodiment of the present invention toThis will be explained with reference to Figures 1(a) and 1(b). The wristwatch 10 shown in Figure 1(a) has a watch body 20 with a crystal 25 located on the viewing side, and an exterior member 30. A display (not shown) is provided on the front side of the watch body 20. The display can display information such as the time, date, and day of the week. This display can be viewed through the crystal 25. The time display on the display can be in various formats, such as analog or digital. In the following explanation, the upper side (i.e., the upper side in Figure 1(a)) when the wristwatch 10 is worn on the wrist and viewed from the viewing side will be referred to as the top, the lower side as the bottom, the left side as the left, and the right side as the right. The viewing side will also be referred to as the front side, and the opposite side (the side facing the wrist) will be referred to as the back side or rear side. The side facing the wrist when the wristwatch 10 is worn on the wrist will be referred to as the inside, and the side opposite the inside will be referred to as the front side.

[0012] The watch body 20 has a generally cylindrical case 21 with a bottom. The case 21 has a generally cylindrical case body 21a and a back cover 21b attached to the rear side of the case body 21a. A watch module 22 is provided inside the case 21. The watch module 22 is equipped with various components necessary for watch functions, such as a circuit section that electrically drives the aforementioned display section to display information such as the time.

[0013] Crystal 25 is located inside the roughly cylindrical case body 21a of case 21. Watch body 20 is provided with sealing members such as packing (not shown) at the connection between crystal 25 and case body 21a, and at the connection between case body 21a and back cover 21b, etc. This makes the inside of case 21 waterproof.

[0014] Furthermore, on the outer periphery of the case body 21a of the case 21, there are formed two female thread portions 21a1 on each of the upper and lower sides, into which screws 38, which will be described later, are threaded.

[0015] The exterior member 30 has a bezel portion 31 that partially covers the watch body 20, and a band portion 32 for attaching the watch body 20 to the wrist. The bezel portion 31 serves as the bezel for the wristwatch 10 and is formed in a circular shape when viewed from the front, just like the watch body 20. The bezel portion 31 has a circular opening 31a on the front side so that the display portion of the watch body 20 can be seen. The bezel portion 31 has a substantially cylindrical outer wall portion 31c and a ring portion 31b formed on the outer periphery of the opening 31a on the front side of the outer wall portion 31c. A C-chamfered portion 31b1 is formed on the ring portion 31b on the viewing side of the periphery of the opening 31a.

[0016] Band pieces 32a and 32b of the band 32 extend from the upper and lower sides of the outer wall 31c of the bezel 31, respectively. The bezel 31 and the band 32 are integrally formed. In FIGS. 1(a) and 1(b), the band 32 is shown schematically with the band 32 cut away. Various types of band 32 can be adopted. For example, one band piece 32a can be provided with multiple engagement holes, and the other band piece 32b can be provided with a buckle equipped with a ring or pin through which the band piece 32a can be passed.

[0017] As shown in FIG. 1( b), the band portion 32 of the exterior member 30 includes a first layer 1 located opposite the arm when worn on the arm, and a second layer 2 located inside the first layer 1, facing the arm. The first layer 1 and the second layer 2 are formed continuously. The second layer 2 is made of a material softer than the first layer 1. For example, in this embodiment, the first layer 1 can be formed of a hard resin material (e.g., hard urethane resin), and the second layer 2 can be formed of a soft resin material (e.g., soft urethane resin). In this embodiment, the first layer 1 of the band portion 32 is formed thinner than the second layer 2. That is, the first layer 1 is formed to a thickness that allows flexibility. Therefore, even if the first layer 1 is made of a hard resin, the band portion 32 can be bent to wrap around the arm.

[0018] Meanwhile, the bezel portion 31 is provided with a third layer 3 that is provided on the side opposite the watch body 20 and is continuous with the first layer 1, and a fourth layer 4 that is provided on the watch body 20 side and is continuous with the second layer 2 and is made of a softer material than the third layer 3. The first layer 1 and the third layer 3, and the second layer 2 and the fourth layer 4, are each formed from the same material. The third layer 3 is formed to be thicker than the first layer 1 of the band portion 32. Therefore, the third layer 3 of the bezel portion 31 does not easily deform. Note that the exterior member 30, in which the first layer 1, the third layer 3, the second layer 2, and the fourth layer 4 are joined together and integrally formed, can be formed integrally with the band portion 32 and the bezel portion 31 by injection molding using a two-color molding method.

[0019] The watch body 20 is stored in a storage section 31d inside the bezel section 31. The storage section 31d is a roughly cylindrical space formed by the fourth layer 4. The inner diameter of the storage section 31d is slightly smaller than the outer diameter of the watch body 20 (i.e., the outer diameter of the case 21 (case body 21a)), so that the fourth layer 4 is slightly compressed when the watch body 20 is stored. The ring section 31b of the bezel section 31 has the third layer 3 arranged on the front side and the fourth layer 4 arranged on the inside. Therefore, the front end face of the watch body 20 abuts against the inner surface of the fourth layer 4 of the ring section 31b. Because the watch body 20 is stored in the storage section 31d in contact with the soft fourth layer 4, the fourth layer 4 can absorb any impact the wristwatch 10 receives if it is dropped, for example.

[0020] The outer wall 31c of the bezel 31 of the exterior member 30 is provided with locking portions 35 that lock the bezel 31 and band 32 to the watch body 20. Two locking portions 35 are provided on each of the upper and lower sides of the outer wall 31c. In this embodiment, the locking portions 35 include a hole 37 that penetrates from the third layer 3 to the fourth layer 4 of the outer wall 31c, and a screw 38 that is inserted into the hole 37 and threadedly engages with the female thread portion 21a1 of the case 21. The hole 37 has a counterbore, and the head of the screw 38 is formed so as not to protrude from the outer surface of the outer wall 31c. The screw 38 (hole 37) is also provided at an angle to match the tapered outer surface of the outer wall 31c.

[0021] In this way, the locking portion 35 screws into the watch body 20 via the third layer 3 to the fourth layer 4 of the bezel portion 31, thereby locking the bezel portion 31 and the band portion 32 to the watch body 20. Therefore, the bezel portion 31 is less likely to deform easily around the locking portion 35 in the hard third layer 3, and therefore the watch body 20 (case 21) can be securely fixed to the bezel portion 31. Note that the locking portion 35 can be formed by a screw engagement using the screw 38 and the female thread portion 21a1, or by a locking portion having a convex portion on one side and a concave portion on the other side. For example, a structure in which a convex portion protruding from the bezel portion 31 via the third layer 3 to the fourth layer 4 engages with a concave portion formed in the watch body 20, or a structure in which a convex portion protruding from the watch body 20 engages with a concave portion formed in the third layer 3 via the fourth layer 4, can also be used.

[0022] It is also possible to configure a wristwatch set that includes multiple types of exterior members 30, each having a first layer 1, a third layer 3, a second layer 2, and a fourth layer 4 formed from resin materials of different colors, and the watch body 20. With this wristwatch set, the user can freely change the exterior members 30 themselves.

[0023] (Second embodiment) Next, a wristwatch 10A according to a second embodiment of the present invention will be described with reference to Figures 2(a) and 2(b). The exterior member 30A of the wristwatch 10A in this embodiment has a first layer 1A and a third layer 3A made of a metal material, instead of the first layer 1 and third layer 3 made of a hard resin material in the first embodiment. The second layer 2 in this embodiment, like the first embodiment, is made of a softer resin material (such as a soft urethane resin) than the first layer 1A and third layer 3A. Note that the same parts and components as those in the first embodiment described above are designated by the same reference numerals, and their description will be omitted or simplified.

[0024] In this embodiment, the ring portion 31b of the bezel portion 31 has a C-chamfered portion 31b1 formed around the periphery of the opening 31a, just like in the first embodiment, but the fourth layer 4 protrudes radially inward from the inside of the third layer 3A at the opening 31a, exposing the fourth layer 4 around the opening 31a. The first layer 1A of the band portion 32 is also provided intermittently, with gaps S formed at predetermined intervals in the length direction of the band portion 32 (the direction in which the band portion 32 extends). When the wristwatch 10A is worn on the wrist, the second layer 2 bends in the gaps S of the first layer 1A, allowing the band portion 32 to bend.

[0025] The joining of the metal first layer 1A and third layer 3A with the soft urethane resin second layer 2 and fourth layer 4 can be carried out by injection molding using insert molding, for example. With wristwatch 10A, second layer 2 is visible through opening 31a and gap S even when worn on the wrist, enhancing the design of wristwatch 10A by allowing the wearer to enjoy the luxurious feel of metal first layer 1A and the various colors of resin second layer 2.

[0026] While the embodiments of the present invention have been described above, the present invention is not limited to these embodiments and can be embodied in various forms. For example, while the fourth layer 4 is provided in the bezel 31 in both the wristwatch 10 of the first embodiment and the wristwatch 10A of the second embodiment, this is not limited to this, and the bezel 31 can also be formed of only the third layer 3. Furthermore, the band 32 (bezel 31) can have not only a two-layer structure of the first layer 1, 1A (third layer 3, 3A) and the second layer 2 (fourth layer 4), but also one or more other layers (for example, other soft resin layers or space layers) between the first layer 1, 1A (third layer 3, 3A) and the second layer 2 (fourth layer 4).

[0027] According to the above-described embodiment, the exterior member 30, 30A includes a band portion 32 for attaching the watch body 20 to the wrist, and the band portion 32 has a first layer 1, 1A located on the side opposite the arm when worn on the arm, and a second layer 2 located on the arm side and made of a softer material than the first layer 1, 1A.

[0028] This allows the soft second layer 2 to fit the arm and provide an exterior member 30, 30A with a band portion 32 that is comfortable to wear, and the first layer 1, 1A makes it possible to provide an exterior member 30, 30A that is less susceptible to damage such as scratches.

[0029] Additionally, the exterior members 30, 30A further include a bezel portion 31 that is integral with the band portion 32 and partially covers the watch body 20, and a locking portion 35 that is provided on the bezel portion 31 and locks the band portion 32 and bezel portion 31 to the watch body 20. This allows the exterior members 30, 30A to have the band portion 32 and bezel portion 31 and be easily replaceable.

[0030] The bezel 31 also has a third layer 3, 3A that is provided on the side opposite the watch body 20 and is continuous with the first layer 1, 1A, and a fourth layer 4 that is provided on the watch body 20 side, is continuous with the second layer 2, and is made of a softer material than the third layer 3. This allows the watch body 20 to be stored in the bezel 31 via the fourth layer 4, resulting in an exterior member 30, 30A that can prevent damage such as scratches with the hard outer third layer 3, while absorbing impacts with the soft inner fourth layer 4.

[0031] Furthermore, the locking portion 35 locks the band portion 32 and bezel portion 31 to the watch body 20 by screwing onto the watch body 20 from the third layer 3 side of the bezel portion 31 via the fourth layer 4. Alternatively, the locking portion 35 locks the band portion 32 and bezel portion 31 to the watch body by having a convex portion of the bezel portion 32 protruding from the third layer 3 through the fourth layer 4 lock into a concave portion of the watch body 20, or by having a convex portion protruding from the watch body 20 lock into a concave portion of the third layer 3 via the fourth layer 4. This allows the watch body 20 (case 21) to be locked to the exterior member 30, 30A with a simple structure, allowing the user to easily replace the exterior member 30, 30A themselves.

[0032] Furthermore, the first layer 1 is formed from a resin material, and the second layer 2 is formed from a resin material that is softer than the first layer. This allows the front and back sides to have different colors or textures, thereby providing an exterior member 30 with enhanced design.

[0033] Furthermore, the first layer 1A is formed from a metal material, and the second layer 2 is formed from a resin material that is softer than the first layer 1. This allows the front side to be made of metal, while the second layer 2 can be formed in a variety of colors, making it possible to provide an exterior member 30A with even greater design potential.

[0034] Furthermore, the first layer 1A of the band portion 32 is formed intermittently in the length direction of the band portion 32. This makes it possible to easily impart flexibility to the first layer 1A even if it is made of metal.

[0035] Additionally, the wristwatch 10, 10A is equipped with an exterior member 30, 30A, which makes it possible to provide a wristwatch 10, 10A that is both more comfortable to wear and less susceptible to breakage.

[0036] Furthermore, by making the wristwatch 10, 10A have one watch body 20 and multiple types of exterior members 30, 30A that can be attached to the watch body 20, it is possible to provide a set of wristwatches 10, 10A that have exterior members 30, 30A with different designs and colors.
