Abstract
A clasp for a pair of wristbands on a digital watch having a pager with a radio frequency receiver such that the wristbands comprise an antenna that has its circuit completed and closed into a loop antenna when a user snaps the wristbands together with the clasp. The clasp has a catch shaft welded or soldered to a clasp body such that electrical contact between the antenna in the wristbands is thereby improved.
