Cartier Astrotourbillon is firstly invented in 2010, and it has been studied by peers since it is launched. With a big dial, Cartier Astrotourbillon is the most representative Complication watches. in 2010, Rontonde de Cartier Astrotourbillon brought a new philosophy which means that tourbillon is no longer confines to the single function, it is also part of the beauty of the watch. Tourbillon is usually applied to offset the gravity to guarantee a better precision. Actually, being different to the traditional tourbillon that is revolves around the axil, Rontonde deCartier Astrotourbillon Skeleton has extensive frame and can makes the balance wheel runs around the dial a round to indicates seconds, just like the moving stars.
In 2012, Cartier IDONE and IDTWO concept watch conducts a series of novel research aiming at exploring the new material that has never been applied to the watch before. Finally, Cartier decide to use the carbon crystal to build the Astrotourbillon and makes it become the first movement that is benefits from it. Cartier replica re-explain how the Astrotourbillon works. It is completely exposed to the nature, and does not connects with other components. Its design and processing is reconsidered and adhere to the strictest rules and proportions. Behind the aesthetic principle, the tourbillon movement with brave design disappear in the typical Cartier Roman time indexes XII and Vi, so it saves spaces for designers to display Astrotourbillon.
Roma time indexes, XII, and VI: the typical 9461 MC movement is a skeleton movement, and only has two Roman time indexes as support. In such a unique structure, those bridges effectively support the movement, and decides its look, and even support the whole structure. Astrotourbillon not only exists on the mechanical structures, it also exists on the tourbillon frame. Actually, the extendable look can increase the revolving angle, and that reminds us of the trace of the star moving in the space.
