Setting the age and moon phase
The FB 1L collection has a complex and unique display of the age and phase of the moon. It consists of a segment numbered from 1 to 14.75 on which a needle goes back and forth continuously, depending on the current moon phase.
A second indication in the opening of the dial at 4 o'clock completes this display by indicating a waxing and waning of the moon.

Scroll"Near Side of the Moon"
Imbued with the scientific spirit of the Enlightenment, the Chronomètre FB 1L.1 is at the crossroads between astronomy and chronometry. A large hand at 6 o’clock indicates the age and phases of the moon in a continuous back and forth movement. This patent-pending complication, combined with the constant force of the FB-T.FC.L calibre, ensures astronomical precision corresponding to a one-day difference in 577 years of operation. Available in a ten-piece limited edition, the FB 1L.1 “Near Side of the Moon” favours a warm and luminous approach. It features a silver-toned dial and a case made of 18-carat white gold and black ceramic lugs, housing the manufacture tourbillon movement with fusee-and-chain transmission.
