Hello All--A few years ago the bezel popped off my son's GMT so I took it to Sutter's here in Chicago (the local RSC). I didn't realize when we got it back that they had put a clear plastic sticker on the back. So he wore it for 1-2 years with the sticker there. The result is a small area of discoloration and pitting in the stainless backplate. I guess salty sweat gets in there? I'm sort of surprised that stainless steel can do that. Should I have the back replaced? Try to buff it out? Or just leave it? Thank you for your advice.

Well, it is called stainless steel! I would probably leave it alone but if it really bothers you, have it refinished like they do to remove engravings from case backs. There is a tutorial in the reference section of this website if you want to try to tackle the job yourself.

Thank you all for your help. I'll see my son this Friday for his birthday and I'll try to get a picture to post. I guess I'll just leave it. Gives the watch "character".

One does wonder, however, if my son's sweat can do this to stainless steel...what does seawater do???

Actually I was told by a qualified person who will remain nameless that the highest incidents of corrosion on the cases were in areas that had high density of chlorinated swimming pools. Much higher than watches in seaboard towns.

As for that spot. Without a photo it is hard to tell but likely a light re satining or bright polish if in that area will remove it.

Acid - Alkaline balance may be more of a culprit than salt.
