Cartel doesn't have their own factory. Any of our TDs can sell you the same watch.
This.
OP, people generally call watches "cartel" because they are either speaking of a model that
a) josh and andrew have posted the watch first before some other dealers (in the case of the yachtmaster in question), and lacking a better designation for it, they called it a cartel watch
or
b) in the case of a lot of vintage models, there are models that J&A carry, and there are models that Angus carries. The other dealerss will sell you either one, but when people talk about "puretime 1680" vs "cartel 1680" that's what they are on about.
At any rate, you can buy that yachtmaster from TimesShops here, or I am pretty certain Ryan/Intime has them listed, and Lion City also has them listed.
