The way the pearl was situated in the triangle on the PO was the first and only thing I had to glance at to know it was a rep. Otherwise it's a spot on PO. Gen pearls never touch or extend beyond the edges of the triangle and they're usually centered (although I have seen them fractions of a mm lower than center, as in this SMP).
Does the gen bezel/insert not fit on the 42? (I've only done the 45)
