Document Type and Number:
WIPO Patent Application WO/2017/073707
Kind Code:
A1
Abstract:
[Problem] To provide: a wristwatch band which allows the number of parts and the number of manufacturing processes to be reduced so as to improve mass productivity and enable cost reduction and which prevents reliability degradation due to deterioration over time; a method for producing the wristwatch band; and a wristwatch. [Solution] This wristwatch band is formed by: integrally forming an inner piece and an outer piece into an integrally formed piece; forming at least two of such integrally formed pieces; forming screw holes in each of the two outer pieces and forming a through-hole in the inner pieces; inserting a rod in the each of the screw holes to connect the two outer pieces and fix the two inner pieces to each other; further inserting a rod through the through-holes to assemble the inner pieces and the outer pieces to form a single band piece block; inserting both ends of the rod inserted in the through-holes into the screw holes of the outer pieces of another single band piece block; and connecting the single band piece blocks in a direction orthogonal to the longitudinal direction of the rod to form a wristwatch band. Furthermore, a wristwatch provided with such a wristwatch band is formed.
