It is the perfect strategy to have a hidden tourbillon as you have the choice to see it when it is flipped. that is always the problem I have with other tourbillions that are hidden as I dont get the choice but here I do, the ultimate luxury!
If you get the chance to see it in real life, pls post pics!! I also agree that DB is back on track and I hope that lots of people buy their watches so that they survive in the far future (hopefully, when I can afford them :p)
