Christophe Claret ( used to be part of AP-RP, nee RPC) but the Hour Striker is a Renaud et Papi development and production.
I agree with most of your comments, and Steve's.
But (both) your comments are predicated on SECONDARY market prices; in the PRIMARY markets, considering MSRP, the AP QP and GP TGBT are not so "undervalued" and the "hot" boutique racer X limited editions or "rumoured to be discontinued" models are not so absurdly over-valued.
Come on; $120k for a 5970!?!
5712 for $60k?!? when the same movement in PRECIOUS metals languish in the low-$10k's?!?
It's a fad/fashion/lemming driven market right now and the only consolation for old timer (read: committed, serious) watch aficionados are the relative "steals" to be had by the great pieces pushed to the shadows.
