TONDAGRAPH GT ROSE GOLD SILVER BLACK COSC

the in-house Caliber PF071, a COSC chronometer-certified movement based on Parmigiani’s ground-breaking and GPHG award-winning Caliber PF361 and storing a 65-hour power reserve. Parmigiani Fleurier takes pardonable pride in the technical refinements that maximize this elite caliber’s efficiency, as well as its top-level haute horlogerie decorations. The integrated chronograph function uses a column wheel rather than a cam, for smoother operation, and a vertical clutch rather than a horizontal one, which increases accuracy by enabling the chronograph to start without an initial jolt. The movement incorporates a cross-bridge instead of a single attachment to better stabilize the balance, whose high frequency of 36,000 vph (5 Hz) means the stopwatch can measure intervals up to 1/10 second. Few modern chronograph calibers can boast this level of accuracy.
