Abstract

PURPOSE:To produce external parts for timepieces which are finished to two colors; the base color of Ti and golden color by forming thin films of an underlying layer consisting of Ti, intermediate layer consisting of a platinum group metal and finishing layer consisting of Au or Au alloy by an ion plating method on a Ti or Ti alloy stock, then partially and mechanical stripping these films. CONSTITUTION:The Ti layer 2 as the underlying layer, one kind 1 of the platinum group metals such as Pd, In, Pt, Rh, and Ru as the intermediate layer and the Au or Au alloy layer 4 as the finishing layer are formed by the ion plating method on the surface of the external parts 3 for timepieces made of lightweight Ti or Ti alloy. The double coated layers are then partially stripped by a mechanical polishing method such as grinding or polishing by which the external parts for the timepieces having the appearance by the two- color finishing of the Ti or Ti alloy stock 3 and the golden color and the excellent adhesiveness, corrosion resistance and wear resistance of the respective layers is obtd.
