a band including a coupling hole in one end portion located coaxially with the attachment hole of the band attachment section; a coupling member inserted into the coupling hole of the band and the attachment hole of the band attachment section and coupling the band with the band attachment section; and a fixing member fixing the coupling member to the attachment hole of the band attachment section or the coupling hole of the band, wherein the coupling member comprises a tubular member having a female screw on an inner peripheral surface and inserted into the coupling hole of the band and the attachment hole of the band attachment section, and a pair of screw members each having a male screw screwed into the female screw of the tubular member and a head section larger than an outer diameter of the tubular member. ### Claim 2 (depends on 1) The wristwatch according to claim 1, wherein the end portion of the band comprises a pair of coupling end sections arranged on both sides of the band attachment section in a manner to straddle the band attachment section, and wherein the coupling hole is provided in each of the pair of coupling end sections. ### Claim 3 (depends on 1) The wristwatch according to claim 1, wherein the band attachment section comprises a pair of attachment sections arranged on both sides of the end portion of the band in a manner to straddle the end portion, and wherein the attachment hole is provided in each of the pair of attachment sections. ### Claim 4 (depends on 1) The wristwatch according to claim 1, wherein the end portion of the band comprises a pair of coupling end sections arranged on both sides of the band attachment section in a manner to straddle the band attachment section, and wherein each coupling hole in the pair of coupling end sections comprises a small-diameter hole section into which the tubular member is inserted, and a large-diameter hole section into which the head section of the screw member is inserted. ### Claim 5 (depends on 1) The wristwatch according to claim 1, wherein the coupling member comprises a first screw member having a male screw section, and a second screw member having a female screw section into which the male screw section of the first screw member is screwed. ### Claim 6 (depends on 2) The wristwatch according to claim 2, wherein the coupling member comprises a first screw member having a male screw section, and a second screw member having a female screw section into which the male screw section of the first screw member is screwed. ### Claim 7 (depends on 3) The wristwatch according to claim 3, wherein the coupling member comprises a first screw member having a male screw section, and a second screw member having a female screw section into which the male screw section of the first screw member is screwed. ### Claim 8 (depends on 1) The wristwatch according to claim 1, wherein the fixing member is a fixing screw screwed into the attachment hole of the band attachment section or the coupling hole of the band along an axial direction so as to fix the coupling member. ### Claim 9 (depends on 2) The wristwatch according to claim 2, wherein the fixing member is a fixing screw screwed into the attachment hole of the band attachment section or the coupling hole of the band along an axial direction so as to fix the coupling member. ### Claim 10 (depends on 3) The wristwatch according to claim 3, wherein the fixing member is a fixing screw screwed into the attachment hole of the band attachment section or the coupling hole of the band along an axial direction so as to fix the coupling member. ### Claim 11 (depends on 8) The wristwatch according to claim 8, wherein a buffer is arranged between the fixing screw and the coupling member. ### Claim 12 (depends on 9) The wristwatch according to claim 9, wherein a buffer is arranged between the fixing screw and the coupling member. ### Claim 13 (depends on 10) The wristwatch according to claim 10, wherein a buffer is arranged between the fixing screw and the coupling member. ### Claim 14 A wristwatch comprising: a case including a band attachment section having an attachment hole; a band including a coupling hole in one end portion located coaxially with the attachment hole of the band attachment section; a coupling member inserted into the coupling hole of the band and the attachment hole of the band attachment section and coupling the band with the band attachment section; and a fixing member fixing the coupling member to the attachment hole of the band attachment section or the coupling hole of the band, wherein the fixing member is a fixing screw screwed into the band attachment section or the end portion of the band in a direction orthogonal to an axial direction of the coupling member so as to fix the coupling member. ### Claim 15 (depends on 14) The wristwatch according to claim 14, wherein an outer periphery of the coupling member has a position regulating groove into which the fixing screw is inserted.
