Duomètre Chronographe (Ref. Q6011421)

The Duomètre system uses two independent gear trains with a shared escapement, giving each function its own dedicated power source. This means the chronograph can be started, stopped, and reset without disturbing the main timekeeping train, a rare engineering achievement.
