Abstract

PURPOSE: To improve surface roughness of parts and satisfy the function thereof by plating a soft metal of superior leveling characteristic on the required parts of watch parts made by blanking a metallic sheet material to required shapes then platig a hard metal thereon.
CONSTITUTION: A daily jumper 12 and the like of watch parts are blanked from a metallic sheet material. Thence, a soft metal 15 of Cu or the like of superior leveling characteristic is plated 1W10μm on the parts of its jumper part 13 and the surface roughness of a sliding surface 14 is set at about 0.1W0.3μm. Further, a hard metal 16 such as Ni, Ni-P, Cr, Pd or the lie is plated 1W5μm on this Cu plating 15. Thereby, the Cu plating 15 is protected and the strength as the jamper 12 is maintained. According to this method, the watch parts such as the jumper and positioning parts of date display wheels, day display wheels, etc. of high reliability are obtained.
