I needed a watch while travelling in Vietnam and bought an F91W from a market stall for a few bucks. It's such a cheap watch I didn't even consider that people sold fakes. A few weeks later I noticed it was slowly losing time and had some other issues, clearly a fake or reject watch. So that's how, I guess.
