Official description

Step by step, Chronométrie Ferdinand Berthoud is producing all-new variations to its collections as it adds carefully thought-out touches to its timepieces. The new FB 1.3-1 “Sapphire Blue” model is no exception. Comprising just 5 numbered watches, this edition offers a new chromatic harmony, structured around an intense, silky translucent blue dial. Its understated sheen pervades every line and detail of the 44 x 13 mm 950 platinum case, featuring mounted grey ceramic lugs.

The inner workings are also redolent with the magic of this new finishing. Seasoned collectors will appreciate all the detailing that characterises the exclusive nature of this limited edition: the timepiece has been fitted with the FB-T.FC-2 calibre, featuring chamfered sapphire crystal half-bridges. The arrow-shaped tourbillon bridge is blue-tinted – a finishing achieved by means of Chemical Vapor Deposition (CVD), a process in which thin films are laid down in a vacuum, ensuring high performance over time and preserving all the finesse and details of the finishes. In addition to this colouring, the new blue dial is decorated with fine lines echoing the blue-tinted hours and minutes hands – as well as the indicator hand for the 53-hour power reserve, located at 9 o’clock.
