> Why would anyone want a mechanical watch?

Because it's neat. Prices generally are above my "I'd pay that for the neat-factor" level though, so there's an element of your suggestion...

You can get plenty of mechanical watches brand new for less than USD 100. The classic Seiko 5 Automatic is USD 64: https://www.worldofwatches.com/seiko?movement=3563&price=-68.
