A watch blank 1 was made by continuously stamping out a 2S aluminum alloy material. Next, as a pretreatment for applying wet plating to the surface of the hour hand blank 1, the surface of the hour hand blank 1 is heated and degreased with alkali in a mixed bath of soda carbonate and bicarbonate, and then the surface is activated by hot immersion in sulfuric acid. Iron is immersed in a Rochelle salt solution to replace zinc, and then electroplated as shown in Figure 1.
Gold plating film 2 was plated at 1 μm. Subsequently, the hour hand is set while fixing the gold-plated hour hand to the outer periphery of the cutting jig 3 made of brass shown in FIGS. 2-1 to 2-3 with lacquer 4. At this time, the cutting jig 3 and the lower surface of the hour hand are brought into complete contact to provide electrical conductivity. Next, the surface of the hour hand was turned with a diamond tool to expose the outer surface of the dial, and then the entire cutting jig 3 was subjected to zinc replacement treatment in the same manner as described above. Further, using the cutting jig 3 as a cathode, a copper plating film 5 of 30 μm was formed in a copper sulfate bath, and then the copper plating film 5 was machined by 20 μm again using a diamond tool to obtain a beautiful mirror surface.

得ることができた。Next, in order to remove the hour hand from the cutting jig 3, it is immersed in a thinner solution, the hour hand is removed, and a final plating film 6 of 0.5μ nickel plating and 0.5μ gold plating is applied by electroplating as shown in FIG. We were able to obtain a beautiful, lightweight hand with an appearance and corrosion resistance equivalent to that of conventional brass hour hands.
