Abstract

PURPOSE:To obtain the watch characterized by easy recognition of time and the like in the darkness and fashionable appearance by providing a light storing material, whose light storing life and luminance life are elongated by providing moisture resistant and light resistant treatments, at a display part such as a dial of the watch. CONSTITUTION:A water proof film and a light resistant film are coated on light storing powder particles after sintering work. Said light storing powder is uniformly impregnated to a resin material, which can be molded, such as polyethylene, polystyrene, and polypropylene. Thus, a light storing sheet 2 with a smooth surface, wherein scratches, cracks, and attachment of dirt on the water proof, light resistant film is prevented, is formed. Said light storing sheet 2 is attached to the surface of the external part such as the dial by double sided bonding tape 3. In this constitution, the bright display of time and a flower pattern 5 in the darkness can be readily seen, and the fashionable watch can be obtained.
