F.P. Journe’s affinity for aluminum and its incredible lightness of being continues with the new Octa Sport – the second creation in Journe’s Sport line. It follows last year’s Centigraphe Sport, the first watch created entirely from aluminum (movement, case, dial and bracelet). The new Octa Sport weighs in at a mere 53 grams, and its automatic movement tips the scale at only 11 grams.
The Octa Sport does not use standard aluminum which is soft and which oxidizes. Rather, it uses an aluminum alloy used in aeronautics. To create fine timepieces using aluminum required Journe to perfect different methods of processing to make the aluminum scratch resistant and give it anti-corrosive and anti-allergic properties. Journe even produced alloys in appropriate colors to produce desired contrasts.
Like all Journe watches, the Octa Sport movement maintains high horology standards. Though fashioned from aluminum alloy, the automatic caliber FPJ 1300-3 offers an adjustable-intertia, free-sprung balance, instant-jump date indication, an off-center rotor with tungsten perimeter weight to maximize winding efficiency, and 120 hours of power reserve. The aluminum alloy receives the usual finishes, including Circular Côtes de Genève on the bridges, circular graining on the baseplate, polished screw heads with chamfered slots, and chamfered and circular grained wheels.
The Octa Sport is available on a rubber strap or bracelet. The bracelet incorporates rubber components to help protect the watch from shocks – rubber inserts are fixed to the sides of the case and the end of each link of the bracelet. The crown and the folding clasp, engraved with the F.P.Journe signature, are also covered with a rubber coating. The folding clasp offers an adjustment system of a half link, or about 4mm.
