Little correction about my previous posts :
The non-Swiss countries of origin I've spotted were on spare parts meant for after-sales service. In the last months, some packaged spare parts started displaying countries of origin and that's where I could see gaskets from China, crystals from Honk Kong and pushers from France.
Having no ties whatsoever with the production, I cannot comment on what's being put in new watches.
I worked at the Swatch Group in the past and we did have Chinese folding clasps of awful quality to place on repairs. The difference in quality was really obvious.
What's great on IWC spare parts is that even though some parts come from abroad, the quality is the same. I've tried comparing Swiss and Chinese gaskets and it's literally impossible to tell the difference in quality.
