not sure assumption about seiko factory using complicated processes is right
Depends on the Seiko. Seiko makes and has made a large number of complicated and historically interesting watches and movements with a story, but your average Seiko won't have that.
If you want a cheap mechanical watch that's a historical 'first' and has an interesting watchmaking story to tell in terms of processes and optimization, get a Swatch Sistem51. It's the first automatic movement that is simple enough and has few enough parts to be mass produced entirely by robot. Of course if that's a 'good' story to tell or not is very much up for debate.
