What causes my watches and jewelry to corrode?

Any watches that I wear start to corrode. I got a new Timex for Christmas and the side that faces my hand is already rotting(little holes, rough spots from pitted metal). My dad has a Seiko and his is okay. Whenever I wear new rings(anything except gold or platinum) they start to corrode and pit. Sometimes they even turn black on the inside and anywhere they touch my skin. Same thing for my dad. Occasionally they'll even turn my fingers green(my husband and I bought matching engraved rings at Disney; mine turned black and my finger green and his was fine). All my earrings have to be for sensitive ears or they get infected and the holes get black around the edges. Anyone know why this happens or what causes it? Anything I can do to save myself from having to buy new watches ever 6 months - a year?

Best answer:
sometimes, your own perspiration causes metals to corrode. This has to do with the composition on your sweat. It's the same reason that some jewelry that isn't gold turns green after a while.

All answer:
Answer 1
salt from the ocean. its in the air or water in general

Answer 7
You might produce body salts that eat away at these items as well.

Answer 8
Because they aren't gold, silver, or platinum, the rings will turn colors and corode when in contact with your sweat, the moisture between your fingers. Watches are the same way when moisture builds up underneath... Try to find a stainless steel watch... They are very affordable and do not corrode.

Answer 9
Try coating the backs in clear fingernail polish. It is caused by the salt and acids your body puts out through your skin.

Answer 10
It means your body has to much acid in it. I experience the same thing. Also if its gold plated and not real sterling silver I get the same results you do. So I just have to pay the price and wear gold only, or sterling silver.

Answer 11
It is prob from you touching them. The oil/salt from your skin/fingers. If you dont clean them every now and then the build up will get to them.

Answer 12
corossion occurs because of oxygen, so water (since it has an oxygen atom in each molecule) would be a source of corrosion. I'd reccomend just investing in real gold/silver/platinum instead of buying cheaper ones earrings-gold.

Answer 13
cheap stuff post to . but silver or gold. beside fool jewerly

Answer 14
Mostly, moisture in the air causes this, but living near an ocean where there is a lot of salt in the air makes it even worse. One thing I use on jewery is toothpaste...it works great.

Answer 15
You also might have a nikel allergy as well. My husband thinks I am pulling his leg when I say that I cannot wear nothing but gold, silver, and platinum. I also suggest the clear nail polish as a barrier between you and your watch. I have given up on wearing a watch and I take my rings off as soon as I get home.

Answer 16
You gotta buy the real stuff! one of the attributes in gold for example is that it does not corode. But most jewelry mixes the gold with other metals (alloy), so if you buy gold with low levels of purity such as 14k or lower, the alloys mixed with the gold would corode when contacted with certain chemicals. If you live next to the ocean, the salt in the air can cause this corosion but chlorine as well as bleaches are attributes, so if you insist in wearing those type of jewelry remove them when going into pools or using tap water.
