An indicating plate for a solar watch, comprising a color diffusion plate which, by virtue of the presence of a coloring agent, a coloring light diffusing agent, a colored translucent substrate, a pattern layer/colored thin film layer and a diffusion layer, is adapted to transmit a portion of light having a wavelength within a range capable of causing a solar cell housed under the indicating plate to generate power. The color diffusion plate is adapted to make it difficult to view the solar cell from the outside through the indicating plate and is also adapted to impart a color tone to the indicating plate.

Indicating plate for watches

A light transmitting metallic dial 50 is disposed above a cell 2 such as an EL device, a solar battery, or the like and the light transmitting type metallic dial 50 is secured by engaging an aligning portion 50b formed on the light transmitting type metallic dial 50 with an aligning portion 4b formed on a casing frame 4. In the light transmitting type metallic dial 50, light transmitting holes 50a and 51 constituting various characters, numerals, patterns, and the like are formed. Further, when the transparent plate is laminated on the light transmitting metallic dial 50, a clearance 7 is formed between the cell 2 and the transparent plate 5 using a spacer or the like.
