A lot of people wear speedmasters because the Apollo astronauts wore them. This is mostly in jest, but if people really wanted to emulate those Apollo astronaut icons, they would choose the most practical options which would be quartz watches, not mechanical watches. They’d be brighter, have better battery, keep better time, more durable, etc
But in seriousness, I totally respect the history and craftsmanship of these watches, just not their practicality in modern day.
I don’t think anyone nowadays is buying a mechanical watch primarily for its technical performance specs. I think it is primarily for aesthetics and history, also happens to be very practical jewelry.
Now that said, when someone has decided they want a mechanical watch because of the reasons above, then specs do come in to play. It is pretty cool that a machine powered by gears and springs can tell time pretty accurately, and more accuracy is better although accuracy is not the only (or even primary) criteria. Same with other specs like water resistance, antimagnetism etc. None of those are reasons to buy a mechanical watch, but once someone has decided to buy a mechanical watch, those do come in to play. Still for me the looks and history are the most important factors.
