Cartier CARTIER true flywheel KF1 floating tourbillon can also be called a flying tourbillon. Compared with the traditional tourbillon, the flying tourbillon frame does not need to be blocked by the "bridge" and can be fully revealed, and has a unique function when operating. The suspension effect looks very dynamic, and can maintain a relatively stable working state in any direction. The Swiss brand did not exhibit the "world's first flying tourbillon" until 2016, which was very important to Cartier. In terms of exploration, there is no end to the exploration in the field of fine watchmaking! Size 40m/13m,,
