It's a little late, but never, ever, ever use Cyanoacrylate glues near watch parts.
Ever seen CSI where they use superglue to pick up fingerprint grease with the fumes? Well, inside your watch is full of little pockets of grease that superglue fumes love to stick to. Fumes on the inside of a crystal will fog it up, too.
However, if you get superglue on anything, Acetone is the way to remove it. This may lift paints (like on dials or hands) but it's sometimes your only choice.
