You are getting increasingly metaphysical.
These watches are built on antiquated technology and, by design, cannot be mass-produced, so clearly they will never lead to technological innovation.
These watches are so rare that they can provide very little beauty. The vast majority of people will never lay eyes on one.
Let me ask you a question: would you support the government purchasing Patek Philippe watches and putting them in libraries for the common people to check out? This would lead to much more beauty than letting them sit in rich people's collections and would encourage even more "human excellence". But I suspect you'd find it a waste of tax money.
