Transparency and lightness

The concept of the FERDINAND BERTHOUD FB 1.4 Chronometer is inspired by an 18th century armillary sphere whose movement, created by Ferdinand Berthoud, indicated the time on a glass dial. The sapphire half-bridges reveal the beauty of the hand-wound Calibre FB-T.FC-2, rhodium-plated and dotted with blue accents, its pillar-type architecture and its reversed and suspended fusee-and-chain transmission mechanism. Thanks to its titanium case, this timepiece with its contemporary design weighs only 80 g, which is extremely light for such a complex timepiece.

 The FERDINAND BERTHOUD FB 1.4 Chronometer is produced in two 20-piece series, a symbolic figure linked to the history of Ferdinand Berthoud, who received an order in 1770 for 20 marine chronometers that would make a vital contribution to the success of major exploration campaigns.

Features

The silver-toned dial with straight-grained lines and an openworked centre bears a silver-toned counter at 12 o’clock displaying the hours and minutes. At 9 o'clock, the power reserve appears through a recessed opening with bevelled edges. The seconds are indicated by a central hand on a translucent matt silver-toned sapphire inner bezel ring. All finishes are entirely hand-crafted.

Calibre FB-T.FC-2 powering the Chronomètre FERDINAND BERTHOUD FB 1.4-2 offers an exceptional level of readability thanks to its three sapphire half-bridges, finely chamfered with satin-finished bevels. This choice highlights the striking beauty of the components. The words "CHRONOMÈTRE SUISSE 46 RUBIS FERDINAND BERTHOUD" are engraved and highlighted in blue.

Visible through the central dial opening, the fourth wheel is independent of the wheel driving the tourbillon carriage. Extremely thin (0.22 mm) and exceptionally long (24.68 mm), the seconds hand fitted to it is made of blued bronze.
