I keep seeing people on forums repeat accusations that "Swiss watches are a scam" and that they are "rebadged Chinese parts", however no-one ever seems to be able to provide any tangible evidence for this.

I get that some specialist watch parts may have to be sourced from Asia, and that this ratio may be higher with companies that have a range of cheaper mass-produced models, but surely the higher up the Swiss watch food chain you go you, in terms of pricing (a few thousand) and prestige…

Swiss watches and Chinese/Asia parts… to what extent is this actually the case?
