Hi Peter,
I saw this one in the windows at the last SIHH and was quite appealed.
Although I really appreciated the Richeville Tourbillon we saw when visiting the manufacture in May, I must confess my perfect choice would be to have the tourbillon in the back, so that it is just for me ! 
The hidden secret!
This example is really a treat and a very brave attempt against the fashion.
Thanks
Dje
