Ferdinand Berthoud Chronomètre FB 1R.6-1

With its original regulator-type display and its ultra-resistant carburised stainless steel case, the Chronomètre FB 1R.6-1 involves transposing into contemporary language the pursuit of excellence undertaken by the master horologist appointed Clockmaker to the French King and Navy. The appearance of the Chronomètre Ferdinand Berthoud FB 1R.6-1 takes its cues from the Marine Chronometer No. 7. and its FB-T.FC.R tourbillon calibre with fusee-and-chain transmission can be admired through a sapphire crystal case-back and two lateral portholes, offering a unique view inside this outstanding chronometer.
