880P PVD movement
The 880P movement is one of thinnest chronograph movements ever made, with a thickness of only 5.6 mm. The chronograph is one of the major watchmaking complications and, among the small number that are made; the 880P is distinguished by its flyback, a high-precision function enabling the chronograph to be reset without interrupting its running. With a single press, the small minutes hand and the central seconds hand "fly back" to zero and immediately start a new timing. The 880P movement is fitted with two barrels, a balance with screws, balance stop and oscillating weight decorated with the Piaget coat-of-arms, in black PVD. Another feature is the 24-hour second time zone indication at 9 o'clock.
The chronograph is controlled by a column wheel coordinating all its phases, and by a vertical coupling clutch which ensures that it is extremely precise. The superimposed faces of the two discs that form the clutch are directly driven to avoid causing the hands to jump and waste energy from the power reserve. Finally, it runs at a higher frequency for increased precision.
Circular Côtes de Genève, a circular-grained mainplate, bevelled bridges, blued screws and an oscillating weight engraved with the Piaget coat-of-arms add the finishing touches to this movement and are reminders of the Swiss watchmaking brand's high aesthetic values.
