Blancpain M185

Blancpain M185 is an automatic monopusher chronograph based on the Frederic Piguet 1185. Manufactured in-house by Blancpain, it belongs to the Fxxx caliber family and remains in production. The monopusher design, where a single crown controls start, stop, and reset functions, distinguishes it from conventional column-wheel chronographs. This movement appears in several of Blancpain's high-end chronograph references.
