Abstract
Abstract An improved watch is provided which includes a lamp mounted in the geometric center of the watch crystal. Light impervious reflecting means overlie the lamp and a minor portion of the crystal reflecting light from the lamp to the watch dial. A pair of electrically conductive leads extend from the lamp to a battery mounted in the watch case and a switch is provided for controlling current to the lamp. The crystal, lamp and leads are integrally formed into a single unit with the leads terminating in a pair of tabs adapted to meet in electrically conducting relationship with the terminals of the battery.
