As a new Pam enthusiast, I can relate.
There was a similar post elsewhere where everything from "conspiracy theories" between rep makers and the brands, to the fact we are 1% of the people who "care" was postulated. Most people settle for the Canal Street or Chinese street vendors, so we are a secondary market.
The same applies to Rolex. Why don't we have a 14060 flawless submariner. It should be the easiest of ALL subs to replicate.
A closed case-back, no-date, no-seconds hand PAM should be super easy. Heck with a closed case back and no seconds hand, you could probably get away with a quartz movement-- as long as everything visual was perfect-- I'd buy.
If they were perfect, what fun would it be learning, and doing mods.
