Not my kind but mechanically interesting: Rotonde de Cartier Astrotourbillon Skeleton with the tourbillon making a complete circle of the dial to mark the seconds. 47mm case in white gold. 100 pcs. We wrote about it last December.

With Pre SIHH 2015 giving us even more to be merry about, we’ve seen seeing some pretty amazing timepieces pop up thats got us very excited. Amongst those are a few stunning pieces from @cartier and in particular the Rotonde de Cartier Astrotourbillon that’s being mainly held together and beautifully presented by Roman numerals at 12 o’clock and 6 o’clock. Probably my favourite from Cartier so far, even more so than the Cartier Crash. Thoughts everyone? Yay or nay?
