As the proud owner of a BK DSSD who has had the opertunity to compare with a GEN, i can tell you i love my watch, but a contender for most accurate rep, it is not. The bezzel and insert are such a givaway. The markers and numbers on the insert are platinum colour on the GEN not white as on the rep. They also appear much sharper and deeper.
That said, it still gets the most wrist time. With a gen insert it would look amazing.
