In 2001, the ‘Octa’ debuted as the first automatic movement to deliver 120 hours of precision timekeeping through reserved-power. Each ‘Octa’ movement is designed to incorporate fully-integrated complications within the same volume. Impressively, all variations within F. P. Journe’s entire ‘Octa’ collection are identical, both in diameter and thickness.
This “Black Label” Octa Automatique Réserve combines extraordinary independent watchmaking with a rare, exclusive black dial. Created in 2008, these Black Label pieces were only offered to existing F. P. Journe clientele and were retailed through the brand’s boutiques. It's very likely that less that less than 20 examples were produced, over a 4-5 year production period, making this an especially rare variant that is hardly seen on the market.
As is characteristic of these Black Label pieces, the dial is rendered completely in black, with the markers and words ‘F. P. Journe - Invenit et Fecit’ inscribed above the subsidiary seconds in a contrasting white. The power reserve is placed on the left of the dial, with a date window above, and corresponding white date discs. Both the seconds sub-dial and power reserve are almost indistinguishable from the dial except for their respective markings the polished hands.
To add to the monochrome colour scheme, the watch is housed in a 38mm platinum case, the watch also bears F. P. Journe's signature ‘flat crown’ with a rope-like pattern. An interesting aspect of this timepiece further lies in the power reserve, as when winding, instead of the indicator heading from 0 to 120, it goes the other way, from 120 to 0. This was a deliberate choice on Journe's part, borrowed from marine chronometer clocks. The reasoning behind this lies in the idea that the power reserve indicator is not meant to tell you how many hours there are left, but instead how many hours since you have wound the watch.
This automatic, self-winding F. P. Journe calibre 1300.3 movement is made of solid 18k rose gold, with Côtes de Genève, constructed with 39 jewels and a shock absorber mechanism. It further features a straight-line lever escapement, and monometallic 4-arm balance with 4 timing weights, adjusted to 5 positions. It includes a self-compensating free-sprung flat balance spring, and an off-centre unidirectional 22-carat gold guilloche rotor.
