Parmigiani’s Tonda PF Chronographe Mystérieux hides its chronograph in plain sight

Parmigiani Fleurier's thirtieth-anniversary Tonda PF Chronographe Mystérieux explores a deceptively simple idea: a complication that need not announce itself every moment. At rest, its blue guilloché dial resembles a restrained three-hand Tonda PF.

A discreet control activates the chronograph display, letting centrally mounted indications measure elapsed time. The unusual mechanical arrangement uses five coaxial hands and a triple-clutch system, making the transformation part of the attraction.

The steel model pairs a 40mm case with the collection's familiar knurled platinum bezel and integrated bracelet. Under the dial is the manufacture's automatic PF053 chronograph movement, offering a stated 60-hour power reserve.

The 2026 launch illustrates Parmigiani's preference for functional elegance: horological complexity kept out of view until it is needed, rather than displayed as an everyday spectacle.
