My (yours too) rich uncle is right about the $100 watch because it represents intrinsic value for that category of object. My uncle rides in a Nissan President because the various years of Rolls Royce have all had niggling problems. Of the many houses he owns I am sure one has as bedrooms and baths that you mention (one has 3 tennis courts and I know he has been there only once because it is in Africa and not convenient), but usually my uncle is very practical about such matters too--not too many rooms and no need to show off.

Sadly, many people buy the hype and crave the lifestyle of illusions (young, thin, handsome, well-traveled, decked out, seen in all the "right" places)--usually wondering why they are not as happy as they deserve to be. Being a genuine watch collector (or any true collector) means that one sees beyond those illusions. The only way to do that is to acquire knowledge before acquiring the baubles.

I had a second thought about a Patek that might cost $26,000 and is fairly new--the 10 day wonder. If you like the Manta Ray case (supposedly requiring 188 separate processes to make) then it might be for you. Horologically it is a milestone. It was made in limited quantities, but pops up for sale. You might check it out.

Best wishes.
