Tonda PF Chronographe MystérieuxPart of a continuing exploration of invisible complications, the Chronographe Mystrieux extends Parmigiani Fleuriers unique approach to time, where function appears only when it holds meaning. An invisible chronograph. Appearing only when needed. At rest, the watch reads as a pure three hand TONDA PF. No counters. No indication. No visual disturbance. The chronograph is present, yet nothing reveals it. A mono pusher at 7: 30 activates the sequence.
