In a further touch of sophistication, Girard-Perregaux has equipped the calibre with its own Microvar variable inertia balance wheel. It features six adjustable screws and two inertia-blocks on its rim, used respectively to set the balance wheel's equilibrium and enable fine adjustment of the movement. This exclusive development ensures increased precision and more stable adjustment.
