<p>A dial of solar-cell timepiece composed of a substrate made of a ceramic material and a colored coating layer formed on the surface of the substrate. The coating layer is characterized by including a colored layer formed by a porcelain paint consisting of metal compounds as its principal component. Since the substrate made of the ceramic material is porous, it diffuses rays of light incident thereto and makes invisible a solar cell disposed on the back side. Since the colored layer is formed by the porcelain paint consisting of the metal compounds as its principal component, it is compatible with the substrate made of the ceramic material and can moreover offer various color tones in accordance with the kind of metal compounds.</p> |
