I loved the One:
I am still totally mad about the II:
I was intrigued by the III, at the point I was on to get it, but I preferred to put that level of money on the Duometre à Chronographe.
I was disappointed by the V. I love the combination of a Chronograph and a World Time, but I would have much preferred having the pivoting case of the " II " for the chronograph functions, rathe than these pushers which are, to me, a step backward.
As for the VII, I never understood why it wasn't called " II ". The differences between the II and the VII are the radial power reserve and the aesthetics...
