You make an awful lot of conclusions in that post and I don't need to put up with it.
When I was asking questions about another brand a while back, I was contacted by PM by another collector who interestingly had two different pieces from two different brands that both had versions of the NE and had both suffered escapement issues diagnosed and recognised by the manufacturers. Of course one of these was an Optimum.
It's a beautful piece and I hope to have one someday.
Anyway, I regret that after sixteen years here I am wasting my time. Goodbye everyone.
