En 2020, la Chronométrie Ferdinand Berthoud dévoilait sa deuxième collection, le Chronomètre FB 2RE. Ce garde-temps marquait un véritable tournant pour la maison : premier boîtier de forme ronde, premier affichage à trois aiguilles centrales et surtout premier mouvement doté d’un double système de régulation associant une fusée-chaîne à un remontoir d’égalité une seconde. Primé pour ses performances chronométriques, ce calibre révèle aujourd’hui davantage son fonctionnement à travers les ponts et platine personnalisables dub Chronomètre FB RES.

Le FB 2RES.2-1, équipé d'un boîtier rond en or rose 18 carats et d'un cadran satiné anthracite, est une des variations proposées par la manufacture.




At the heart of this timepiece beats the Calibre FB-RES.FC, regulated by fusee-and-chain transmission and a one-second remontoire. The purpose of this full-fledged chronometric complication is to even out the energy coming from the barrel and transmitted to the escapement. The device relies on a spring positioned between the two organs. It temporarily stores a small amount of energy, which is then delivered to the balance. The charge/discharge frequency of this buffer energy is very short: one second.


The construction with three bridges converging towards the dial centre is directly inspired by a skeletonised table clock made by Ferdinand Berthoud circa 1775. The similarity does not end there, as that clock displaying the hours, minutes, seconds, age of the Moon, calendar and zodiac signs was also equipped with a “remontoir d’égalité”.


Each wheel, bridge and screw is entirely hand-decorated. An extraordinary level of manual finishing has been applied in order to reveal the beauty of each component. Placed end to end, all the angles of the wheels and their bridges, as well as those revealed at the heart of the 9 o'clock power-reserve display, represent more than two linear metres filed and polished by hand.
