    The new Chronomètre FB 2T tourbillon with fusee-and-chain and sapphire bridges is the Final Edition of the Caliber FB-T.FC launched in 2015, housed for the first time in a round case. Limited and numbered to 38 movements.

    Its vertical satin-brushed brass dial ruthenium coated, is framed by a round rose gold case.  The transparent sapphire case-back provides a chance to admire the 1,120-part tourbillon movement with fusee-and-chain transmission. 

    Featuring a striking structure and driving exceptionally readable indications, caliber FB-T.FC is equipped with an exclusive constant-force regulation system with suspended fusée and chain transmission, equipped with a differential winding system. It also has a highly distinctive power-reserve mechanism.  It’s precision and rate accuracy is certified by the Swiss Official Chronometer Testing Institute.

    When the mainspring is associated with a fusée, the barrel drum turns in one direction when the spring winds down and in the opposite direction when it is wound up, thus causing the chain to wrap around the drum. A distinctive feature of caliber FB-T.FC lies in the fact that its fusée mechanism has been equipped with an unusually designed differential gear.

    The case of the Chronomètre Ferdinand Berthoud FB 2T is built according to a distinctive architecture inspired both by the Marine Clocks of Ferdinand Berthoud and by their gimbal suspension system typical of onboard chronometers.  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.
