Does replating with gold depreciate the value of a watch ? I mean gold plating a gold plated or a 18k watch is a bad idea? I hope you understand what i am asking
No, actually I don't. Why would you need to plate a layer of gold over top a solid gold watch? Give us more details on what you're trying to accomplish. If it's putting more gold back on a case to make it more crisp, plating isn't going to do it.
i have seen posts here about re-plating a gold-plated watch where the plating has worn off. understand that. find the idea of plating a solid gold watch very odd.
