At the 2015 edition of Salon International de la Haute Horlogerie (SIHH), which takes place January 19 to 23 in Geneva, the French brand is presenting a new version of its Rotonde de Cartier Astrotourbillon watch.

This skeletonized watch exhibits the best of the brand’s innovation and mastery, both technical and aesthetic.

After offering a new take on the traditional tourbillon with the first Rotonde de Cartier Astrotourbillon in 2010, and after adding carbon crystal to the mix in 2012, Cartier is highlighting its sculptural prowess with this latest edition, which is entirely skeletonized.

The parts that make up the extraordinary Astrotourbillon complication blend into a dial that consists only of two roman numerals, XII and VI, the signatures of Cartier timepieces.

Light and airy, the Rotonde de Cartier Astrotourbillon Skeleton Calibre 9461 MC is a testament to the brand’s innovation and mastery, as much from an aesthetic perspective as from a technical one.

On the technical side, watch enthusiasts will appreciate the Calibre 9461 MC, a hand-wound mechanical movement with an Astrotourbillon complication that completes one rotation per minute.

The watch comes in a 47mm 18K grey gold case and is produced in a limited edition of just 100 numbered units.
