well obviously it's a different movement, it's about 99.500$ more!
and since the whole point of a tourbillon is to look at it, they cannot possibly make an accurate replica

EDIT: I see what you mean, the chinese tourbillon is not a replication of any existing movement as far as I know.
try and get a noobfactory one and go with a clone ETA movement ... even if it breaks, you could always get a gen ETA and then you can be sure it'll last
