The strotourbillon celestial rotating tourbillon was first created by Cartier in 2010, and since the advent of it, it has caused competitive research in the watchmaking industry. Combined with the magnificent dial, this model has now become one of the most representative complications in Cartier’s fine watchmaking series.
Birth and evolution of Astrotourbillon
In 2010, Cartier brought a new concept to the traditional tourbillon structure through the Rotonde de Cartier Astrotourbillon astronomical tourbillon watch. For the first time, the tourbillon is no longer limited to its single functionality, that is, to reduce the effect of gravity to ensure more accurate travel time performance, but also to become a part of the aesthetics of the watch. In fact, unlike the classic tourbillon that only rotates around its own central axis, the Astrotourbillon astronomical tourbillon is unique in its extended frame, which allows the balance wheel to rotate around the dial once a minute to indicate the second, It works like a planet.
In 2012, Cartier launched a series of innovative research projects around the CartierIDONE concept watch and CartierIDTWO concept watch, aimed at exploring new materials with excellent performance that have never appeared in the field of watchmaking. In the end, Cartier decided to use the carbon crystal material to build the Astrotourbillon astronomical running tourbillon, making it the first Cartier mass-produced movement to benefit from this technological innovation.
2014: The Mystery of the Astrotourbillon
Cartier reinterpreted the Astrotourbillon astronomical tourbillon in the form of sculpture. It is completely exposed and not connected to any other mechanical parts, so that it can be seen more clearly. Its design and production are all reconsidered and follow the strictest rules of proportion, harmony and balance. The aesthetic concept behind this highlights the structure of the movement with a bold and innovative design, making it ‘disappear’ behind Cartier’s iconic Roman numerals XII and VI on the dial, thus leaving a wide range for watchmakers. Space, showing the spectacular beauty of the Astrotourbillon celestial rotating tourbillon, and at the same time making it move more widely.
Roman numerals XII and VI: Cartier’s iconic design
The main splint of the 9461MC movement is completely hollowed out, supported only by two Roman numeral hour markers. In this unique architecture, these bridges form a strong movement, define its appearance, and support the entire mechanical structure.
Astrotourbillon’s volley rotation
Not only in the mechanical structure, the celestial design also exists in the tourbillon frame. In fact, its extended shape can increase the amplitude of rotation, reminiscent of the trajectory of celestial bodies in space. Combining the innovative evolution of technology with a bold artistic perspective, the Rotondede Cartier Astrotourbillon skeleton tourbillon skeleton watch shows the brand’s ambitions-whether from a technical or aesthetic perspective, it is full of imagination and creativity, A breakthrough in Cartier’s fine watchmaking collection. It achieves a double feat—simplifying the components while giving the movement a sculptural appearance, and at the same time creating a wider operating space for the unique complexity of the Astrotourbillon astronomical tourbillon.
