I am also concerned about the bubble in watches, particulary Pateks. They have always been expensive, but prices both new and resale continue to climb. I do not intend to sell any of my watches, but it is nice to know that several are worth more than I paid on the secondary market. I know that trees do not grow to the sky and that anyone who buys at today's high prices has a very low probability of seeing their watch appreciate. I assume that the premiums in the secondary market for a few hot watches ie 5980 will evaporate in the near future as supply matches up with demand. Anytime I can buy a "hot" watch at my AD I assume that supply is finally matching demand. With some patience I have gotten most everything I want from an AD, but the latest price increases from Patek will cause me to pause some of my purchases at least for a while.
