Ultra-complicated Movement ST8520

The double-axis tourbillon is an evolution of the traditional tourbillon, featuring an additional axis on top of the original one-minute rotation axis. This enhancement elevates the visual experience to the next level. With the addition of the second axis, the balance structure of the original tourbillon needs to be redesigned to achieve overall rotational balance. This not only increases the technical requirements but also further complicates the production and manufacturing process.
