Ferdinand Berthoud FB 2TV.1 exposes a 1,240-part flying tourbillon

The Chronomètre FB 2TV.1 opens Ferdinand Berthoud’s Mesure du Temps 1787 collection with its mechanics displayed on the dial side. The 44 mm white-gold case is 15.46 mm thick and rated to 30 metres. Its hand-sanded nickel-silver movement carries the hours and minutes at 12, central seconds and a power-reserve display near 7:30.

Hand-wound Calibre FB-TV.FC contains 1,240 components, including 777 parts in the 279 mm chain. A flying tourbillon works with fusee-and-chain constant force, while a crown-integrated pusher resets the central seconds without stopping the mechanism. The COSC-certified calibre runs at 3 Hz and stores 60 hours of power. Production is limited by the manufacture’s capacity.
