I suspect it's due to enthusiasm and lack of specialist knowledge. For example, I am helping a work colleague who is trying to find a vintage Speedmaster. When he looks at them he has no real idea whether all the bits are original & isn't completely sure how important it is to him that, for example, the bezel is correct, as opposed to a correct but slightly damaged bezel.
Easiest giveaway is "stubbies". They are the continuation lines behind the hour markers and are only ever found on fake dials.
I reported it too. Since he'd added a comment that only the movement was definitely correct and the rest he wasn't saying, it contravened eBay rules anyway.
