Ferdinand Berthoud FB 1
Issued in an exclusive 50-piece series, the Chronomètre FERDINAND BERTHOUD FB 1.1 is the first model in the collection. Its vertical satin-brushed ruthenium dial is framed by an octagonal white gold case with titanium lugs. Its sides feature four watertight portholes revealing the intricate workings of Calibre FB-T.FC with its pillar-type architecture. The transparent sapphire case-back provides a chance to admire the 1,120-part tourbillon movement with fusee-and-chain transmission. Four patent applications have been filed for certain mechanisms of this COSC-certified movement. Both contemporary and technical, this exceptional model reinterprets the mechanical prowess and extreme precision of the Marine Chronometers that Ferdinand Berthoud produced in the 18th century for the French King and Navy.
The unprecedented Calibre FB-T.FC with its pillar-type architecture is equipped with a low-frequency reversed tourbillon with direct-drive centre seconds and constant-force regulation via suspended fusee-and-chain transmission system that enables it to occupy a minimum of space at the heart of the movement. The result is an incredibly light mechanism, which may be admired through the four lateral portholes of the octagonal case.
