The movement has been reconstructed in its entirety in order to make the micro-rotor visible from the dial side. This innovative layout not only represents an additional technical challenge for the designers, but also breathes new life in aesthetic terms, by strengthening the spectacular appearance of the dial and its very contemporary design.」2月8日 0時01分
