Cartier’s kicked their pre-SIHH announcements off with two novelties that build on their haute horlogerie narrative.

The first piece is the Rotonde De Cartier Skeleton Mysterious Double Tourbillon Watch, which is powered by the calibre 9465MC. The movement itself was first announced in 2013 and features a tourbillon mechanism that seemingly floats in nothingness. What’s even more trippy is that while the tourbillon makes a complete rotation every 60 seconds, the entire tourbillon cage, too, takes a complete turn, within the chasm, once every five minutes.

With the addition of the skeletonization to this new version of the calibre 9465MC, the mystery of the Mysterious Double Tourbillon is now further amplified. But this new aesthetic isn’t simply for the sake of a fresh look. Consider the Roman Numeral hour markers that now have been transformed into the bridges that hold the entire thing together — some major architectural re-designs to original movement would’ve had to be made in order for it to retain its chronometric integrity.

The second piece that’s been announced, however, is something quite completely hot out of the oven. Continuing the theme of mystery and borrowing from Cariter’s earlier Day and Night complication, the new Mysterious Day & Night Watch boasts an animated, transparent skyline, which doubles up as the day/night and hour indicator. Minutes are thereafter reflected on the lower half of the dial using a retrograde mechanism.

The movement created for the watch, the calibre 9982MC, is a new addition to Cartier’s library of internally developed movements — but it’s obviously one that incorporates and reinterprets complications what were already part of the maison’s knowhow.

Going back to the Rotonde De Cartier Skeleton Mysterious Double Tourbillon Watch, while the one here is shown with the 45mm polished platinum case, there is also a second option with the case bezel paved with baguette-cut diamonds. Both versions will be issued as a limited edition of 30 numbered pieces.

The Rotonde De Cartier Mysterious Day & Night Watch shown here is the 40mm 18k pink gold version, but there will also be another one in white gold. These will be part of their regular production as of 2018.
