The movement’s aesthetic is enhanced by grained and sandblasted plates and bridges, adorned with Geneva stripes.

Completing the watch are two dials: one silvered and the other sunray opaline. They host an ensemble of 31 hands and 9 discs, all meticulously arranged to display the multitude of functions
