Well... The parts market for vintage Rolex is in my opinion a completely autonomous monster from even sales of complete vintage watches, per se. You have folks out there trying to collect parts that simply aren't in production any longer, and people are willing to fork out some outrageous money to build their stash of spares since RSC's are either replacing parts with new, non-period correct service parts, or simply not servicing certain watches at all. So, to fuel that demand, there are individuals out there who are feeding that market by supplying stock that was bought out from, say a retiring watch maker (who held a parts account), or buying some of the un-desireable no B&P/documents pieces and parting them out. It's a crazy dynamic, but folks are making a killing in parts. Makes me think I got into the wrong biz....
