I can't speak to authenticity (though that dial is pretty suspicious), but for me, that isn't NEARLY enough 'pie pan' for me to spend pie-pan money on.
The case has a few things that are suspicious to me beyond being pretty polished (one of the best parts of these cases is how 'sharp' the legs are)., like lacking a gold-hallmark (I suspect the PBF is a makers mark?).
That said, even if it IS completely authentic, this isn't a watch I would buy.
