Ferdinand Berthoud devoted his life to experimentation and to passing on his knowledge by publishing numerous specialized works and training apprentices. The Chronomètre FB RSM continues this tradition by enabling a young watchmaker from the University of Neuchâtel to participate in the development of the movement as part of his graduation project. The Chronomètre FB 2RSM.2-1 is a tourbillon regulator with the fusee-and-chain transmission, and for the very first time, it incorporates an independent deadbeat seconds visible on the dial side and a stop-seconds mechanism.
