So I currently only own a marathon tsar mechanical but am a big watch fan in general. They are a little expensive though.
My 5 favorites.
Pam 329
Rolex submariner/seadweller
Patek 5070r $$$$$$$
Bell and Ross br-01 series
Rolex Daytona
I'm also really liking the new bell and Ross ww1 watches but the band is kinda slim
