FERDINAND BERTHOUD – FB 1R.6-1


STAINLESS STEEL ACCURACY

Ferdinand Berthoud, the watchmaker, stands out by designing highly complex watches. A new edition limited to 20 pieces pays homage to this creative power.

To take on the oceans, clocks embarked on board ships in the 18th century accumulated technical innovations to guarantee timekeeping and physical reliability. With the FB 1R.6-1, Ferdinand Berthoud has taken inspiration from a historic model, the Sea Clock n°7, created for the French Navy, for which the watchmaker of the same name was awarded the official title of mechanical clockmaker. On the façade, the timepiece catches the eye with its original composition and aesthetic power. Above a refined satin-brushed nickel silver and black rhodium dial, a slender bronze hand takes care of the regulator display. Three off-centred apertures around the rim provide additional time information. The hours are shown at 2 o’clock on a sapphire disc with a glare-proof coating. At 12 o’clock, the minutes tick away on an aperture leaving the traditional-style workings partly visible. The third aperture features an original power reserve indicator (53 hours).

At the heart of the FB 1R.6-1 is a hand-wound movement enhanced by a tourbillon driving the time elements. It features a constant force regulator with a “suspended” fusée and chain mechanism. The calibre’s accuracy is certified by the COSC (Contrôle Officiel Suisse des Chronomètres).

Like its illustrious forebear, the 44mm-wide case, made of a type of hardened steel used in the medical sector, is built to last. It has a cylinder that has been reinforced using a thermochemical process to make it as hard as ceramic, with two side pieces fixed to it. The pieces are pierced at 2 and 11 o’clock to reveal the fusée and chain mechanism. The exemplary finishes on the calibre can be seen and enjoyed through the sapphire crystal.
