Abstract

PURPOSE:To obtain the titled parts having superior function and fine golden appearance by successively forming underlayers and a Pd layer on the surface of each of external parts for a timepiece made of brass and by coating the Pd layer with a TiN film by ion plating. CONSTITUTION:The surface of each of external parts for a timepiece formed by forging brass having superior workability, e.g., a brass watchase 1 is polished. A Cu layer 2 and an Ni layer 3 as underlayers are formed on the polished surface by electroplating or electroless plating and a Pd or Rh layer 4 is further formed on the layer 3 by plating. The resulting case is placed in an ion plating device and ion plating is carried out by heating, bombarding and TiN film coating stages to form a TiN film 5.
