The Chronomètre FB 2T – Final Edition presents for the first time the tourbillon movement with fusee-and-chain transmission in a round case. The exterior of these final 38 examples of this calibre can be customizable, offering the collector the opportunity to choose the case material as well as the colour of the dial or the hands.
The reference FB 2T.2-1 is equipped with an 18-carat rose gold with a ruthenium satin-brushed dial.
Calibre FB-T.FC-2 is distinguished by three bevelled and engraved sapphire half-bridges, supported by polished steel pillars providing a chance to admire the movement’s main organs, as well as an understated hand-sandblasted finish resulting in a particularly modern appearance.
Positioned at 6 o'clock, the tourbillon carriage engages directly with the seconds (fourth) wheel thanks to a wheel located on its axis whose diameter and properties are identical to those of the seconds. The two wheels thus make a complete rotation in 60 seconds: the seconds (fourth) wheel in a clockwise direction and the tourbillon wheel counter-clockwise.
The crown is equipped with a safety device to protect the movement from excessive winding. A dynamometric spring hidden in the heart of this so-called "disengageable" crown makes it possible to limit the torque transmitted to the motor organ. When the tension required to wind the movement exceeds the permitted values, the dynamometric spring disengages, thus preventing the crown from driving the winding pinion.
The Chronomètre FB 2T is the final 38-piece edition featuring the tourbillon movement with fusee-and-chain housed in a round case. The reference FB 2T.1 is equipped with an 18-carat white gold case with a blue satin-brushed dial.
