Zusammenfassung:	PURPOSE:To obtain a colored wrist watch case high in the fashionability and excellent in the wear resistance by subjecting the watch case to the honing, laminating successively an inorganic glass primary coat, a colored luster layer and an inorganic glass protective layer and coating them thereon. CONSTITUTION:An inorganic glass primary coat 1a is formed in about 5-10mu film thickness on both a case 1 with back and the surface of a bezel made of stainless steel. A colored luster layer 1b is formed on this surface by a spray coating method or the like. Then an inorganic glass protective layer 1c is formed on the surface. As the colored luster, the different color is respectively used for the middle with back and the bezel. By this method, the colored wrist watch case excellent in wear resistance is obtained.
