Does anyone have some insight into the quality of materials in Chinese watch movements, in particular the factories other than Sea-Gull? Are any of the balance wheel and hairspring materials comparable to that of their Swiss/Japanese counterparts? Is there a Chinese glycodur balance wheel, or nivaflex hairspring? And how do the factories rank in terms of quality of stamping the components, and making good screws? DG, Hangzhou, Liaocheng, etc.
If anyone has any background on these, let's hear it.
Thanks!
