The Breitling Watch Source Forums

I can somewhat understand your situation. The crown on my SA sometimes get very hard to unscrew. I never overtighten it, just screw it in normally. Then it seems to self-tighten sometimes, making it difficult to unscrew. Almost so that it's not enough friction in your fingers (and no, my fingers aren't greasy...) and I need to take help from a cloth or glove to unscrew it. I have no idea why this happens, but since the rest of the watch is working as a clock I'm not too concerned.
