Speaking of serious vintage watches, I went to the Museum of Art for my bday and they had several pocketwatches on display at their "Canton Market" exhibit. These would be sold in the Canton (Guangzhou) market in the late 1800's, the only places where foreigners were allowed to be at the time... The decoration on these movements was anything but primitive
They had an even older one from the 1600's, when they would only have an hour hand, since movements weren't accurate enough to bother with minutes at the time. It was really cool to see these in person.
Here's a better picture of a couple from watchmaker Juvet
Surprisingly these sell for like
$2500 each at auction (well that listing was a long time ago, but still). There must be thousands of them out there
The brand still exists! It's a brand with a pretty interesting history, with connections to China going back almost 2 centuries
