I know that the Chinese have a bad reputation for their manufacturing practices , and for the most part there’s lots of cheap ones where quality is little more than a suggestion. However, I’ve gotten some decent ones. I’ve bought some quartz watches form the usual contender AliExpress and even some mechanical ones and I’ve been shocked by the quality of these sub $100 watches.
They churn out a lot of crappy stuff that the entire world buys, but they are capable of making very high end watches (many god tier luxury brands source items/parts from China ) . If you want to see a good example of quality check out Atelier Wen .
