Flamenco, very glad you enjoyed the pictures, and also that you enjoy them on your iPhone 
I got the Tianjin chrono and Chunlei dual time from sellers on another forum. I've never seen the Chunlei brand anywhere else. The Tianjin can be purchased from online resellers, just google "tianjin 1963 chronograph". There is a place in the Netherlands that has the best pricing and options I've seen, although I never tried them. There are a number of other places at higher prices, again, no experience there either.
As was mentioned in a post above, Tianjin Seagull has been making these chrono movements for a long time and are pretty good at it. They should be servicable; although even if not, the replacement cost is pretty reasonable!
The Regulator came from Perpetual Watch Company's online shop (just google that full name). It will take a week or so for the watch to arrive, and they have a very good reputation for sales and service. They have another chrono that you might like as well. The watch comes with a rubber strap (not so hot) an a leather strap (not bad). Funny thing, I didn't like their black leather strap on the regulator, but it looks OK on a different watch
not sure why.
Finally, if you are interested in Chinese horology (so to speak), then just google Chinese Watch Wiki.
