I just bought a casio the black and white one that says the hundreds. It looks all good everything but I noticed that the buckle on mine isn't the same as the same watch I see on youtube and google. The authentic model has the black and round buckle. Mine is silver and square! it also says Casio china on the inner side. For those of you who have owned this same watch, please look at the pictures and tell me if this is a copy. I really appreciate all your feedbacks.
