To be fair to him, the lower carats of gold do corrode somewhat, and even 24 carat gold can rub off and create a black mark, if there's anything abrasive on the skin (some cosmetics do that for example). It would be worth checking the hallmarks.I am glad you added this. I had a 24 carat gold thick chain bracelet that was beautiful to me. I would only wear it for special occasions.
Even it turned my lower arm black and started whithering away with a pock marked suface that was embarassing and sad. I ended up selling the gold that was left.
I feel, as if, the great minds here are starting to narrow down the causes and will have an epiphany soon. Although the gold is really not the question. The watch battery longevity is the actual question, unless they go hand in hand for other materials than gold. ie: Silver and Plastic type watch back covers that don't leave my skin black or pock mark the surface. It has been suggested that I try the "Air type" of battery that is used in hearing aides to see if that makes a difference. I will do that soon.
