Abstract
A wrist watch with hour and minute hands in the form of rotatable circular films, having an electrostatic shielding device which grounds a glass of the watch through a back cover of the watch, to eliminate static electricity produced in the glass. Also, because of the use of thin rotatable circular films for the minute and hour hands, the thickness of the watch can be considerably reduced.
