The latest Chronométrie Ferdinand Berthoud watch is inspired by marine chronometers, for which the 18th-century watchmaker is famous. Driven by a fusee-and-chain mechanism, this regulator features an original display of each function, split over the dial. Hours are displayed in an arched window at 2 o’clock, and minutes are shown in a subdial at 12 o’clock. A complicated power reserve display dominates an opening in the space between 8 o’clock and 10 o’clock on the dial. The seconds are directly linked to the 60-second tourbillon, which is featured on the caseback side, along with the mobile-cone power reserve system. The dial is nickel silver that is given a vertical satin-brushed finish and then black rhodium-plated. It is a 20-piece limited edition.
