There are countless Chinese-made automatic wristwatches on AliExpress, most of which have very low cost movements which keep time OK-ish. The movements are serviceable (ie they can be stripped, cleaned, reassembled, lubed and regulated), but spare parts are not normally available. Having said that, replacement movements are cheap.
Almost all the "brands" are just meaningless names printed on the dial - they tell you nothing about the quality of the watch. In fact, if you recognise the brand, don't buy it because it will be a fake. (Unless you want to support the faking of Western brands, I guess.) And this is the problem when buying Chinese products, including watches: China can and does make extremely cheap and nasty stuff, but is also perfectly capable of making high quality stuff. The problem is, it's often almost impossible to know which you will be getting from the advert.
An example of a "good" (not brilliant) Chinese brand is Sea Gull. They make a Chinese version of the Swiss ETA 2824-2 movement which is at least as good as the low-to-mid-range versions of the ETA movement.
In summary, China makes a wide range of very cheap to moderately good watches. You cannot trust the brand - if you've heard of it, it's a fake; if you haven't, it's just a meaningless name. Despite all of the above, I am happy to have well over a dozen Chinese-made watches in my collection. None were expensive - I bought them because they are interesting or amusing in some way.
The only Chinese brand that I feel has some degree of trustworthiness is Sea Gull.
If you want a higher level of confidence, and want to buy a decent watch, then I recommend one of the Japanese brands: Seiko, Citizen or Casio. The Casio range is entirely quartz, so probably not what you are looking for. Seiko and Citizen both make mechanical watches, many of them automatics. Both are good, trustworthy brands, but it is probably true to say that Seiko is the top Japanese brand for mechanical watches.
I no longer recommend Swiss watches for a good reason, but it's something I will go into in a separate post.
So, in summary:
1/ China makes a very wide range of automatic watches. The cost is usually very low, and so is the quality, but they are usable and if you like the looks, consider buying. You will find endless examples on AliExpress.
2/ China is capable of matching the low-to-mid-range Swiss watch movements in terms of quality and performance. The problem is, they usually don't, and ordinary punters like us cannot tell what quality we'll be getting from looking at the advert.
3/ On AliExpress, if you see a watch with a brand you have heard of, it will be a fake. If it's a brand you haven't heard of, it will just be a meaningless name printed on the dial. The exception is Sea Gull - they are slightly better than the Chinese average.
4/ If you want a good quality automatic watch I recommend going Japanese: Seiko are my first choice, but Citizen also make a range of mechanical watches for you to check out.
An even shorter summary: forget Chinese, forget Swiss - buy yourself a Seiko.
