Ferdinand Berthoud as a brand, represents a love letter to the history of Marine Chronometers. The third model to leave the workshops was the FB3, a hand wound chronometer with helical hairspring visible through the sapphire crystal window in the case band. With a dedication to chronometry and classic, 'hand made', watchmaking, only 25 pieces are planned to be be crafted each year. Seemingly the very first in this execution to come to market, this example in contemporary rose gold with exposed anthracite grey grené plates is presented with its original box, travel pouch, warranty, chronometer certificate and USB key.
