A beginner watch is a Seiko SKX (now the 5 line) at US$200, one can also do Hamilton field watches, Longines, Stowa, Nomos, Omega or IWC, etc for a few hundred to a few thousand.

Watch Youtubers like The Urban Gentry, Teddy Baldassarre, etc, cover (and own) watches from all sort of price levels (as do folks in /r/Watches, where you'll see state of the collection (SOTC) posts that have Casio G-shocks).
