The Ferdinand Berthoud FB 1.3-1 is powered by the manually-wound COSC-certified FB-T.FC-2 caliber and features a tourbillon and a fusee and chain constant force mechanism. The movement draws inspiration from marine chronometers, of which Ferdinand Berthoud was one of the most legendary clockmakers.
The new translucent blue dial is decorated with fine lines matching the blue-tinted hour and minute hands, as well as the indicator hand for the 53-hour power reserve, located at nine o’clock.
The timepiece comes in a 44mm octagonal platinum case with anthracite-gray ceramic lug elements.
The timepiece comes paired with a hand-stitched, rolled-edge alligator strap made from a single piece of leather.
