Abstract
PURPOSE:To prevent the fading of external parts for a timepiece and to improve the corrosion resistance by forming passivating films by chromating on prescribed pink Au alloy plating films so as to prevent the diffusion of oxygen. CONSTITUTION:External parts for a timepiece are formed by coating pink Au alloy plating films with passivating films by chromating. The Au alloy contains Au and Cu as principal components and components selected among Ag, Cd, Pd and Zn. The passivating films prevent the diffusion of oxygen into the plating films.
