Great recommendations! I would add some other “boutique” brands: STOWA (German) is definitely work a look. Their military aviators are a little above your limit at ~%650, but it’s definitely worth it. They are spectacular.
Absolutely STOWA. In the German “boutique” vein although still a little out of price range is Archimede which has a little bit of everything from field-like to aviator to dive to railroad to classic… too many choices and too little time to wear them all!
