The Breilting Motif, anchor, automatic movement and every thing else you mentioned are easily replicated even to the worst degree of quality. What is not easily replicated it the functionality of the tourbillion movement. The display of a balance wheel does not cut it. Check out some videos on Youtube under “Tourbillion” and you can see first hand how these movements function and why they have a 6 figure price tag attached to them.
To answer your question “Surely they wouldn,t go to that much trouble. Would they??” Yes they would! Not with this model, but with others yet. Take the Breilting Super Ocean Steel Fish. One of the best out of the box Reps around. Has been for some time.
I along with other have seen many of these Bentley Tourbillions. I actually used to work with a guy that tried telling me his was real and swore buy it. I did not call him out as if it makes him happy then that is all the matters. Just like if you like the watch, then that is all the matters.
FYI
