Chronometer FB RSM

The Chronomètre Ferdinand Berthoud FB RSM celebrates the Marine Clock no. 8 produced by Ferdinand Berthoud in 1768. Powered by the limited production FB-T.FC-RSM caliber - a tourbillon regulator with fusee-and-chain transmission - incorporates two incredible complications for the first time: independent deadbeat seconds visible on the dial side and a stop-seconds mechanism. The FB RSM is limited to just 20 pieces in 18-carat white or rose gold, each with the unique watch number on the dial.
