Abstract
Abstract A wrist watch has an electric bulb for illuminating the dial and a battery lodged in a housing independent of the watch movement housing and having an elastically mounted cover. Electrical circuit means for connecting the battery to the bulb include a switch operable to illuminate the dial by a pressure exerted on the cover by the wrist upon which the watch is worn.
