Unrelenting and uncompromising excellence
The Chronomètre FERDINAND BERTHOUD FB 1.3 was born from Karl-Friedrich Scheufele's passion for time-measuring instruments and is inspired by the Marine Chronometers that Ferdinand Berthoud created in the 18th century. With its pillar-type construction and its direct-drive centre seconds, its unique Calibre FB-T.FC is the thinnest in its class. Its fusee-and-chain transmission mechanism is equipped with a barrel featuring with Malte Cross stopwork device and a fusee with satellite differential gear system. The power-reserve mechanism consists of a suspended mobile cone. Whether straight-graining on the dial or mirror polishing on the tourbillon bridge, the finishes are entirely hand-crafted using traditional tools and quality controls are carried out under a 6x loupe.
