It is solid white gold, not plating. 18K white gold is an alloy of 75% gold and 25% other metal to make it white. Usually, this other metal is nickel, silver, and/or palladium. Some white gold is plated with rhodium to make it whiter. However, Patek’s white gold is unplated.I'm not an experienced welder, but have worked a bit with Mig and Tig, oh yeah and brazing.
@TheFoo 's watch has me perplexed. I thought white gold was a plating process. I didn't know "Solid white gold" was a real thing. . . is it?
I can't imagine he rounded an edge without going through the plating. Wouldn't the actual base of the case be Bronze or something like that? The base is Gold?
White gold? Or yellow gold then plated???? (brain imploding at this point)
At the moment i am imagining that they would have to add material of the base metal then re-plate it?
How are they going to add the material? With a metal filler rod? What method?
So they add material. then re-cut the edge and re-plate it?
Aaaargh, dammit @TheFoo why do you have to be this way?
They add material using a laser welder, which creates tiny welds that don’t damage the surrounding area. After welding enough material to exceed the height of the surrounding, undamaged surface, the surface is polished until that excess material is completely flush.
