The product known as the Starwheel from AP? If so, then why is Urwerk a totally original concept again? I think in this industry, there are no such things left as original concepts. There are either borrowed concepts, modified concepts, or re-hashed concepts. Even the great F.P Journe built his hame on borrowed ideas.
As for being purely original, I'm not sure you could claim RM is either. The case shape is not a new design (c'mon, you really believe the tonneau shape was invented by him?), the internal workings were most likely done by a hired gun (as with most other brands out there), and the movement isn't even an in-house calibre (Renaud & Papi?). So, why does it warrant such a high price tag and such awe? Yes, the entire package is an enticing one. But again, that's marketing. Not watchmaking.
Sorry, not to be a troll here, but just wanted to point out some parts that I couldn't agree with while reading this long thread.
