Overview
Central hands for the Octa
The F.P. Journe Octa Automatique Lune Boutique Edition, reference AL, in 18K 6N gold with a blackened guilloché silver dial, 10.6 mm high. Self-winding calibre 1300.3 with central hours and minutes, small seconds at 4:30, large date, power reserve at 9 o'clock and moon phase.
The Boutique Edition sets a blackened guilloché silver dial in an 18K 6N gold case. F.P. Journe gives its production as 2009 to 2018 and states that the black-dial Boutique Edition on a 6N gold case was sold only in its boutiques and Espaces, for every model apart from the striking watches.
F.P. Journe presented the Octa line in 2001: automatic chronometers with a 120-hour reserve, every complication in the same case size. The Automatique Lune came with the revised calibre 1300.3. Journe says some clients found the original Octa dial hard to read, so he used the new calibre to build two models with central hands, the Automatique Réserve and the Automatique Lune, their dials inspired by the Chronomètre Souverain, which won the men's watch prize at the Geneva watchmaking Grand Prix in 2005.
Calibre 1300.3 answered a second observation. Journe reports that a friend's Octa was never fully wound because his right hand barely moved while he worked at a computer. The new rotor winds in one direction only and runs on ceramic balls that let it turn one way and lock it in the other; when the wearer is still, it swings back to its resting position, so each small movement becomes winding. The five-day reserve and the variable inertia balance of the Octa are kept.
For collectors
Both changes in this model came from owners, in Journe's own account: one about legibility, answered with central hands, and one about a watch that was never fully wound, answered with the one-way ball-bearing rotor. The moon and the reserve are indications the Octa already carried; what the Automatique changes is how the watch is read and how it is wound.
Key details
Design and engineering
- One-way rotor on ceramic ballsThe off-centre rotor drives in one direction and locks in the other, so short, small movements of a still wrist are turned into winding rather than lost in the rotor swinging back and forth.
- Slipping mainspringAt full wind the spring slips in its barrel, so the rotor cannot overwind it.
- Variable inertia balanceFree-sprung, with four inertia weights setting the rate, a flat microflamed Anachron spring, Nivatronic laser collet fixing, a mobile stud holder and a pinned stud. In-line lever escapement, 15-tooth wheel.
- Central handsHours and minutes at the centre, small seconds at 4:30, large date, reserve at 9 o'clock and moon phase, a layout inspired by the Chronomètre Souverain.
- Three-position crownPosition 2 sets the date by turning the crown in opposite directions; position 3 sets the time. The date changes instantaneously.
