If that was originally a Seiko watch, I think it would have 4R35 movement (Seiko branded version), not NH35A
"This is not a fake, it's an aftermarket case"... well the aftermarket case is a fake Santos case, and the aftermarket dial is a fake Seiko dial... OK the movement is real Seiko movement
So the question is, why make a fake Seiko that looks like a fake Santos and put a Seiko logo instead of Cartier?
