Casio Oceanus S100 is made of titanium, adjusts itself over the radio[0], understands 29th of February, sets itself on/off DST, never needs tinkering or battery change, and sells for a whooping $350. It's the watch you can set all your other watches to.

[0] Don't have radio coverage where you live? "There's an app for that" -- or several -- that simulate radio control signals.

Ooh, that is a nice quartz watch! Really good review here: https://www.peterferenczi.com/blog/2023/3/19/the-casio-ocean...
