ABSTRACT:
A combined watch and wristband is provided by an injection molding defining a central watch casing and auxiliary casings on either side of the central casing, the molding having opposite ends extending outwardly from the auxiliary casings encircling around towards each other to terminate in spaced relationship to define a wristband integral with the watch casing. An integral metallic stamping of similar exterior contour overlies the injection molding and is provided with central and auxiliary openings in registration with the central casing and auxiliary casings respectively. The metallic strip includes integrally formed spring contacts extending oppositely from diametrical peripheral portions of the central portion of the strip to overlie the auxiliary casings and provide electrical connections for batteries in the casings. The assembly is sonic welded together and one extending end of the metallic stamping serves as a substitute for a normal link in the clasp structure.
