With its thickness of 4.65 mm, the 883P calibre is the thinnest hand-wound flyback chronograph movement in the world. Equipped with a 50-hour power reserve, it features hours and minutes hands, a small seconds display at 6 o'clock, a chronograph with a 30-minute counter at 3 o'clock, and a 24-hour second time zone display at 9 o'clock. Thanks to its flyback function, a single press of the button can reset the chronograph hands to zero and automatically start a new timing cycle. Furthermore, the chronograph is governed by a column wheel to coordinate all its phases, and a vertical clutch system to assure perfect accuracy. The 883P flyback chronograph movement features finishes crafted in the purest tradition of fine watchmaking: circular Côtes de Genève, circular-grained main plate, bevelled bridges, sunburst wheels and blued screws.
