The Chronomètre FB RSM reinterprets the architecture and design of the Marine Clock no. 8 produced by the master clockmaker in Paris in 1768. Only 20 movements will be produced, and several key exterior elements can be chosen by the collector. They may be fitted inside a round or octagonal case. The FB-T.FC-RSM calibre, a tourbillon regulator with fusee-and-chain transmission, for the first time incorporates an independent deadbeat seconds visible on the dial side and a stop-seconds mechanism.
