I think the bridge on the traditional models are beautiful when black polished, but having no bridge on the flying Tourbillon makes things more unobstructed and certainly makes it easier to measure seconds 
On the flip side, I did like the unobstructed view of the back on the manual wind models - the rotor in this automatic Tourbillon movement does cover the beauty in certain angles. The VC Overseas Tourbillon does an incredible job here - and I almost jumped over to VC but decided to be patient for the right allocation.
Anyway, can't have everything yet...who knows what will be introduced next year and years later 
Cheers
