So it's a question of what utility or value you derive from it.
Personally if I didn't have a smart watch that tracked activity, showed me the weather forecast, let me glance at a notification without taking my phone out of my pocket etc. I would have no watch. That's what I had before my first Apple Watch.
If you find value and enjoyment from your mechanical watches, then that is the point, and they don't need to do anything else to justify it.
