Rich don't twist my arm, Chronomatics are very difficult especially since during the last years prices have risen and dials have resourfaced.
I personnally believe in the earlier numbers and the early first series case features which are pretty evident to see at least in metal.
I am sure that Jeffs watch is original as was mine in the sale first owner with all the paperwork. The other watches you have mentioned I don't know.
