The rest could come from other places.
But why be obsessed with Swiss? There are interesting watches made in other places. Today with proliferation of inexpensive CNC and 3D machines it becomes shooting fish in a barrel.
30 years ago I was given a nice Swiss watch made by August Reymond - it was very well made and quite inexpensive by 1995 standards - I think it was about $150 then. I liked it but it was too small for my wrist, even its strap too short.
