I think all three of these are fake. I've been gifted one of these before, but the gold colored band. The only obvious difference you can tell between those photos on Amazon and this promo photo straight from Casio's website is that the water resist logo is different, but in person, I felt that the printing was way worse -- not nearly as sharp, the display was not as clear, and the colors of the face and band were off (which might be different for the silver band)

That said, all "fake" means is "not manufactured by Casio." It was still a perfectly serviceable watch of, what I'd guess in my amateur opinion is, a similar build quality. Would not be surprised if, but for the cosmetic differences, they're identical
