Most of my seikos all have movements made in malaysia or vietnam. Hardly see one made in japan other than the Grand seikos

This one is a bit less user friendly, because they place some of the automatic winding components onto the train wheel bridge. So you have take that bridge off, flip it over and take more parts off of it, including some pretty fiddly components, and the tiniest shock jewels you'll see instead of simple cups. The "Swiss" movements I have worked on have placed the winding works on its own module that sits on the underside of the movement. Also a lot of the gear train is stacked on top of each other, so you have to get your oiling done in order during assembly, whereas with more human-friendly designs you can generally do the oiling once the train is assembled. That's been my very short experience with ETA and Rolex and Omega at least
But it's good in that there aren't a bunch of tiny springs in there. Only a couple springs, and they're attached to other, bigger parts
The calendar has a lot of parts too, but that's pretty common.
The most annoying part was getting the winding stem in with the pinion, clutch, AND another setting wheel, with nothing to set them on. This guy makes it look easy here (timestamped)
