FB 1.2 Rose Gold

Issued in an exclusive 50-piece series, the Chronom├Ętre FERDINAND BERTHOUD FB 1.2 is the first model in the collection. Its vertical satin-brushed black dial is framed by an octagonal rose gold case with a black ceramic inter-horn space. 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.
