Abstract:
To provide a timepiece faceplate having appropriate light permeability with excellent aesthetic appearance having glittering property, and an electrical timepiece equipped with a solar battery, a timepiece faceplate of the invention includes a faceplate main body that has light permeability, and a glittering layer that is provided on either one of a front surface side and a back surface side of the faceplate main body and is configured by dispersing a glittering powder into a light permeable resin. The glittering powder is configured by laminating a metallic oxide film above one surface side of a plate shaped base material, which has light permeability, and the glittering powder is a lamination powder that an average grain diameter is more than 10 μm and less than 90 μm.
