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 unique executin FB 2T.2-red is equipped with an sandblasted titanium case with a vibrand black & red 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.

Inspired by the Marine Chronometer No. 7 that Ferdinand Berthoud produced in 1767, the construction and the regulator-type display of the FERDINAND BERTHOUD FB 1R.6-1 chronometer overturn traditions. Composed of the rear side of the black rhodium-plated nickel silver regulator plate adorned with straight-grained lines, the dial features three openings: one for the hours (at 2 o’clock), another for the minutes (at 12 o’clock) and a third for the power reserve (at 10 o’clock).

The FB-T.FC.R calibre, with its pillar-type architecture, features a direct-drive centre seconds tourbillon whose constant force is provided by a fusee-and-chain transmission mechanism incorporating a satellite differential gear and Malte Cross stopwork device. Continuing the tradition of precision inherited from Ferdinand Berthoud, this COSC-certified timepiece is available as a 20-piece limited edition in carburised steel.

Produced exclusively for ART in TIME, the Chronometer FERDINAND BERTHOUD FB 1.6-4 Oeuvre d’Or is a piece unique. Its sandblasted white gold with hand engravings is framed by an octagonal DCL stainless steel case with a black titanium inter-horn space. Its sides feature two 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 Chronomètre FB 3SPC draws its stylistic, technical and aesthetic inspiration from a rare and exceptional creation, the No. 26 decimal watch, made in 1793 by Louis Berthoud. Calibre FB-SPC is based on a cylindrical balance-spring, a rare watchmaking speciality. It is the only one of its kind to satisfy the chronometric (precision timekeeping) criteria of the COSC: ISO 3159 certification made possible only by the precision adjustments performed by the Manufacture’s watchmakers. The FB 3SPC.1, one of the two versions available, is equipped with an 18-carat white gold case, 2N pale yellow gold movement components and an eggshell-coloured dial in sandblasted silver-toned brass.

Appearing at 9 o’clock, the three main escapement organs – the balance-wheel, pallet-lever and escape-wheel – are thus individualised, distinct and prominent. This ample space dedicated to the regulating organ enables its operation to be admired in full, and the cylindrical balance-spring to be seen beating throughout the three-day power reserve, including through a large water-resistant porthole created in the case middle. Its round case, available in 18-carat white or rose gold, recalls the curves of pocket watches from the early 19th century, such as the decimal watch No. 26, made in 1793 by Louis Berthoud and now on display within the Chronométrie Ferdinand Berthoud heritage collection in Fleurier. The mainplate is placed at the heart of Calibre FB-SPC and the components are assembled on either side of it. On the dial side, a close-knit array of six bridges traces curves and lines directly inspired by the work of Louis Berthoud. They are echoed on the back by ten other bridges forming an intimately juxtaposed mosaic.
