Abstract
A structure for coupling a back cover with a case band in a wrist watch which comprises a case band having a long groove on the outer wall of a band attaching portion, a spring member being fitted in said long groove of the case band so as to outwardly project a protruded portion of said spring member and a part thereof being fixed to said case band, a back cover having a side wall with a long hole bored at the position corresponding to that of said spring member, and an elastic member for energizing and engaging said back cover with said case band along the axial direction thereof so as to cover a module. According to this structure, a compact, thin and highly waterproof wrist watch can be assembled, while disassembly thereof can be effected by merely pushing a portion of said spring member protruded from said long hole thereinto.
