Limited Edition of 10 Pieces Each
In 1770, Ferdinand Berthoud was awarded the title of "Clockmaker and Mechanic by appointment to the French King and Navy". Chronométrie Ferdinand Berthoud is celebrating this 250th anniversary by unveiling a new collection inspired by the Marine Clock No.6: the Chronomètre FB 2RE.
This new timepiece reinterprets the architecture and design of this Marine Clock. Fitted along its middle with a large panoramic window, the round 18-carat gold case frames a grand feu enamel dial with a complex two-tiered construction.
Beneath this traditional, uncluttered display lies an exceptional mechanism: the new Chronomètre FB 2RE combines the emblematic fusee-and-chain transmission with a one-second remontoir d'égalité mechanism. A model charting a course towards a new world of mechanical precision entirely in keeping with the lifework of Ferdinand Berthoud.
