Good Afternoon, I am a vintage watch enthusiast and am considering
getting involved in watch case repair. Many of these vintage wrist
watches are either 10K or 14K gold-filled, that is, a thick layer of
gold sandwiched with a base metal such as brass or nickel (not a
plating process). Many watches exhibit wear-through at high points
on the cases where the base metal will show through, the gold having
been worn away over the years.
I would imagine I could buy some gold wire that has a melting point
lower than that of the 10K or 14K gold used in the manufacture of
these watch cases. Would I use a jewelers torch to melt the wire
into the worn area? One I get a layer down I could file and sand the
area to get the restoration complete.
Some watches are yellow gold-filled, some are rose (also called pink
or coral), and some are white gold-filled. Do you have wire that
comes in colors?
I would appreciate any insight you can give me on my desire to get
into vintage wrist watch case repair.
