Secondly, your argument is fairly analogous to having to tune a Violin when perfectly good Violin virtual instruments and samples exist, indistinguishable for the use-case in question. By framing the question like that you're kind of missing the point about Horology and owning mechanical trinkets for the sake of marvelling at their construction and innovation.
People used to wear gold as jewelry thousands of years ago. And some people still do just that. That behavior predates a great many currencies. For example I'm pretty confident people shall still wear gold as jewelry long after the EUR currency shall be dead.
Enter any jewelry store in the west now and they'll tell you: men buy jewelry too now. But it didn't use to be that way: typically a watch was the only jewelry a man was allowed to wear.
I've got a very nice japanese mechanical watch which shows day of the week, day of the month and power reserve in addition of the time. Got it for 300 EUR brand new at a "family sale".
When I'm wearing that watch there's some device responsible for the zombification of the west I can do without: my smartphone. Adjusting it manually once in a while doesn't seem that bad of a deal.
I have a very cheap (~$10) mechanical pocket watch, and it's not all that accurate in keeping time. But to me, winding the watch and adjusting the time is part of the fun. Even more fun is watching the gears and listening to the ticks, and pulling out my pocket watch when my friends started looking at their smartwatches.
Historically speaking, this was only true in recent times (the last few hundred years). Visit a history museum and you'll find all sorts of jewellery and ornaments worn by men over time.
However, at that time scale, I have to wonder whether the mechanism can, or should, run for over a century without stopping, which would seem to imply running without being cleaned or serviced beyond a certain point.
