In other words, I own the watch because I enjoy it for its own sake. It's a beautiful piece of handcrafted machinery. It's not supposed to have superlative practical utility, nor does any serious watch house actually strive for that. These timepieces are a form of art, and whether or not you appreciate them has no bearing on the fact that their manufacturers are under no illusions of their practicality.
Don't generalize your perception of the entire industry based on your experience or preconception of a relatively diminutive portion of its consumers. There are people who buy Rolexes because it's a good way to show off money, but there are many other people who honestly buy them because Rolex genuinely manufactures high quality mechanical watches. My experience as a collector is that most people do not buy these to show off. Rationally, a Vacheron Constantin is an inefficient vehicle for doing so - it looks pretty, but virtually no one will recognize it nor even comment on it.
I collect and restore fountain pens, and I have to disagree. There is surely a segment of the market that this fits well (Montblanc, for instance), but the majority of the fountain pen market is < $100.
For example, I have three pens with me today: a TWSBI Vac700, a Pilot Falcon, and a Sheaffer Snorkel. The TWSBI and Pilot are modern and cost $70 and $110 respectively, but the Snorkel is vintage (1958) and I paid $35 for it.
Excellent modern fountain pens can be had for <$20.
That's ridiculous, he (or she) doesn't do it just for the money, the work itself is satisfying entirely separate from the monetary compensation. I'm sure he could find a job with pretty much the same income but less responsibility and therefore less stress if he felt like it but then he wouldn't have the satisfaction of building such an object.
I don't make watches but I do write some moderately complex software (I try to avoid it being complicated). It pays me the money that I use to feed my family but that is far from the only reason I do it. It is a satisfying endeavour in itself, sometimes just to see the customer's delight in using the finished article and sometimes my own delight in achieving a neat and efficient solution.
Back to physical things, I used to be a test equipment designer and the one thing I regret about moving into software is that I can no longer show my creations to people like my wife and have her see even a slight glimmer of what I have achieved.
In fact they're more like cult power objects - what anthropologists call fetish objects, which confer an implied cultural blessing on their owners.
