The Chronomètre FB 3SPC by Ferdinand Berthoud

In October 2022, Chronométrie Ferdinand Berthoud unveiled the Chronomètre FB 3SPC, the third pillar of its collections inspired by and following in the tradition of the famed 18th-century watchmaker for whom the brand was named. The FB 3SPC incorporates key elements of marine chronometers such as those produced by the historical atelier of Ferdinand Berthoud, one of those elements being the cylindrical hairspring. Chronométrie Ferdinand Berthoud undertook three years of research and development to create the FB 3SPC, the first and only wristwatch with a cylindrical hairspring that has been officially certified as a chronometer by the Contrôle Officiel Suisse des Chronomètres (COSC).
