Every time I acquired a "vintage" watch, I saw that there's always pitting on top of the thread area where the backcover sits. I know that "alley" like areas like this attract rust to build up. This got me thinking, if I got a watch long enough so that it has built some pitting, it must be a very special watch. I wouldn't want my special pretty watch to develop pitting, so perhaps it's a good idea if this watch's case isn't iron based. Yeah I'm thinking about a case made of titanium, gold, platinum, bronze (?), etc. Something like this would be a good choice:
I know that pitting takes a long time to develop, and the usual 316L SS is perhaps already rust proof enough that we won't see a speck of rust eating away our valuable watch. But I think a watch with a pitting proof case would be ideal if it's to be a special one.
How about you? Have you ever thought that rust would be an issue on your watch?
Unfortunately those materials which rust can't eat away the material itself are usually softer than SS, so it's a bit of trade off....
