I hate the stock strap on mine as well. the claps had a tendency to jab the inside of my wrist.

Hamilton khaki King. its a great watch and i personally have one. not worth nearly as much as any of the oris watches especially if any of those were something like a big crown pointer date. but the khaki king is a great watch regardless.

buy yourself some flitz polishing compound on amazon and give the crown a polish and that watch will really pop.

the PRX is a great watch, I personally have the ice blue automatic as i love the waffle dial.

I wouldn’t call the Shunbun underrated. its the watch that even the most vehement grand Seiko haters admit is still fucking beautiful
