Abstract
The transparency of a watch crystal having scratches in the outer surface is improved by applying thereto a piece of a thermoplastic urethane film. The film has an acrylic adhesive on one surface and a protective clear coat on the other surface. The scratched cover of the watch crystal and the adhesive is thoroughly wetted with an alcohol water solution (25% alcohol, 75% water). The film is then placed on the scratched cover and stretched to cover and conform to the surface thereof. Pressure is then applied to the film to drive out from thereunder excess of the water alcohol solution. After a short drying period the watch is ready for use.
