Abstract

PURPOSE:To enable uniformly bright indication of a watch and simplify the construction of the watch by a mechanism wherein a necessary mark is attached on the analog illumination photoconductive plate portion of the illumination photoconductive plate being made integral with the digital illumination photoconductive plate by providing a cutoff hole thereon. CONSTITUTION:Digital and analog illumination photoconductive plates 10A and 10B are integrally formed on a photoconductive plate 10 of acrylic material or the like formed with a cutout 10C for a lamp 19. Marks 20 such as times, name and the like are applied to the plate 10B as commonly used as a dial plate. With such a configuration it can indicate both digital and analog displays in uniform and bright manner with a simple construction.
