I ask this because a buddy of mine told me that his stainless watch has rust spots on it. I told him that it is either a cheap fake with crap steel or something strange happened. I have been in heavy salt spray areas (Florida, Hawaii, Caribbean, etc) and have worn stainless watches for extended periods with not even a hint of rust. He said it was surface rust and he was able to remove it with a rough pad for washing dishes or something. He's basically going diving and snorkeling in places that I have been in as well, nothing unusual and all I can think of is maybe something caustic got in touch with the watch or maybe it is the rough finish on the steel that is having issues.
So have any of you actually heard of rusting of stainless finish?
