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 18K gold case frames a grand feu enamel dial with complex two-tiered construction.
