I'd love to have one of these but for $5k, I'll just buy another watch or two.
HRoi, this might be a more subtle alternative, same German brand for $400. Also has an additional 7-watch storage so it works as a a 13-watch case.
Personally, I find the bracelet a bit much on the Parmigiani. I like it a lot more on a strap. IMHO strap helps define and display the unusual case shape, and probably makes it look better with a suit or for more elegant events. I think with the bracelet the watch case kind of blends into the bracelet and the lugs and case just get a bit lost in the bracelet. However, since you already own the bracelet so there is no harm in giving the bracelet another chance. It might grow on you. If not you can always go back to a strap. In the end, you know your preferences and sense of style better than any of us here would, so go with whatever makes you smile most when you look at your wrist!
Since you already have a chrono, I would say the Sub. But I have a soft spot from the Portuguese Chrono. I hate the way the numbers are cut off but it I adore the dial. It is clean for a Chrono and the white dial with blued numerals and hands looks fantastic. I see they offer a blue dial with silver indices but I have not seen it in person.
