I do believe that the impression that most folks have of something this expensive is nothing short of perfection and when issues arise, the marketing myth disappears in an instant and things become emotional ..anger, frustration, etc. Certainly very understandable.
This is when the comparisons of watches that have been owned for years and worn very hard that cost a fraction (less than the sales tax on a simple PP) are working just fine and your expensive watch, which is supposedly of the highest level of manufacture,assembly, and built for generations of use, has problems within a relatively short period of time and probably at a pretty steep price. And I'm not talking about watches which have been worn hard or abused.
Does this sound or feel familiar? I've heard it many times and experienced some of it myself.
The first Rolls Royce I purchased was a 7 year old Silver Shadow (many, many years ago) that the salesman assured me of the level of quality and craftsmanship built into every car and that I should not be concerned or have any issues with it, so I bought it and into the legend. Two weeks later, at an intersection, smoke (almost like a burning house) starts coming out from under the hood. Two weeks and $5,000 later, I realized that there was a difference in the legend and reality. The sales managers response to me was, we don't make them to break but things can happen. I think the same can be said about expensive watches.
A lot of companies are living on the coat-tails of their legend exploiting it to the fullest extent possible. Once the money has changed hands, you have a warranty for two years, but afterward you're on your own with whatever happens. It just seems that demand (money) and production is adversely interfering with the status of the legend.
I do think that if problems and issues (the reality) with newer pieces continue, the legend will begin to suffer as your comments seem to suggest.
