Abstract
A strap for holding a wristwatch has a pair of separable flexible strap ends adapted to curve around the wrist and to overlap one another to provide an overlapped section. At least one strap end of thermoplastic material has particles of permanently magnetizable material embedded in the thermoplastic material and magnetized to provide rows of alternating magnetic poles. The strap ends have surfaces contacting one another throughout the overlapped section and mutually nesting uniformly spaced interlocking teeth, whereby the magnetized particles provide a holding force resisting separation of the strap ends, while the nested teeth prevent sliding disengagement movement between strap ends.
