Case back is on point to gen 360, only part that isn't is I guess the enameling, the ack wears off fast... Not sure if that happens with the gen pams too, as my two gens have silver engraved back and don't have that issue..
I have the newest dsn 360, with they greyish pvd case and the piece looks amazing! Only issue I have is that the hands Luke are a tad lighter than the numerals on the dial, the gen has them all the same shade lume , that creamy/orange patina look... Ah well
