If it truly is the Rolex of backplates (and I'd love a Rolex, preferably a classic) then:
1-It will only perform like an average backplate, substantially less than many
2-It will be pretty, not as pretty as some, but also will be made with obsolete technology
3-It will require expensive annual service from an authorized dealer, which will cost more than purchasing a new above-average backplate
4-It will be widely counterfeited and sold for $10 in Chinatown
5-Bad people will sneak up on you and threaten to take it off with a machete if you don't hand it over NOW. Especially if you get the 24K gold model set with small diamonds.
Did I miss anything there?
