re: WYWI / WYBI Richard Mille watch?

Something I wonder about these watches that are priced in the hundreds of thousands and more, or even the tens of thousands. The market for them has to be incredibly restricted. A person has to be wealthy enough to afford them, and the person has to be more than a mere millionaire to justify spending the price of a nice house on a watch. Then the person in addition also has to actually care about watches and even more one specific watch to want to add it to their collection.

It just seems crazy to me. There can't be more than at most a few hundred people in the world who are willing to spend $1.7m on a watch. Even that seems kind of like a stretch to me. Maybe I'm off base though. I haven't personally ever mingled with the ultra wealthy.
