Cal. 1181 (also called FP 11.81, Piguet, F. Piguet, etc) is a column wheel rattrapante chronograph movement produced by Frédéric Piguet. It is closely related to Cal. FP 1180, which was introduced in 1987 as the thinnest column wheel chronograph movement ever produced.
Cal. FP 1181 includes many high-end features, including a column wheel, vertical clutch, Triovis micrometer regulator, and Kif Ultraflex anti-shock. The rattrapante function is controlled by a pusher at 10:00.
