Count the unusual things about this watch and you run out of fingers before you run out of features. It is an Octa Chronographe, a reference F.P. Journe built for only four years. It has a brass movement, which places it before the manufacture changed everything over to solid 18K rose gold. Its dial is made partly from 18K yellow gold, a metal that appears almost nowhere else in a catalog built on red golds. The case is platinum at 38 mm, a size the industry abandoned shortly afterward. And the complication is a flyback chronograph with a sixty-minute counter and a large date. Any one of those would make a watch worth noting. Together they describe something close to a one-off, assembled from a set of decisions the manufacture made briefly and then stopped making. It has been out of production for a very long time.
Yellow gold behind cool silver subdials in a platinum case is a three-way arrangement and none of the three agrees with the others. The plate is warm and frankly yellow, in a way red gold never quite is; the three subdials for the hours, minutes and small seconds are whitened guilloche silver, cut separately and screwed to that plate with steel circles so they stand slightly proud of it; and the case surrounding the whole of it is cold gray platinum. Journe made no visible attempt whatsoever to reconcile the three of them. What holds the composition together in the end is the steel: the bright circles ringing each of the subdials pick up the platinum out at the perimeter and carry that cool note inward across the warm plate, so the eye reads the watch as a related set of parts rather than as three unconnected materials sharing a space by accident. At 38 mm the whole assembly is notably compact, and a chronograph dial carrying three counters and a date aperture at that diameter is dense by any standard you care to apply. The case stands 10.6 mm tall with a sapphire crystal set into the back, through which the brass plates are plainly visible.
Sixty minutes is a deliberate choice on a chronograph counter and worth explaining, because thirty is far more common. A minute counter records how many complete minutes the chronograph has been running, stepping once each time the seconds hand passes twelve, and the capacity of that counter sets the longest interval the watch can time without the wearer having to keep count of the laps themselves. Thirty minutes covers most of what anybody actually times in practice, and it allows a larger and more legible subdial for a given area of dial, which is the reason the industry settled on it as the default arrangement. Sixty doubles the available range at the cost of cramming twice as many graduations into precisely the same space, which makes the counter harder to read quickly. Journe chose sixty regardless, which suits a chronograph intended to be genuinely used rather than merely operated for amusement, and it pairs sensibly with a flyback function that exists precisely in order to time consecutive intervals one after another. The calibre 1300.3 in this form runs to 254 parts and 32 jewels at 21,600 alternations per hour, carrying a reserve of 120 hours and wound by the off-center 22K gold rotor that the whole Octa family shares between it.
Dial materials varied more on this reference than on very nearly anything else Journe has ever made, which tells you something useful about the period in which it was built. Across the Octa Chronographe's short life the plate appeared in white gold, in 5N gold and in yellow gold, each of them paired with the same whitened guilloche silver subdials, and fitted into cases of both platinum and 18K 6N gold. That is a considerable amount of variation for a watch produced across only four years by a manufacture making a few hundred pieces in a year. The likeliest explanation is that the early period simply worked differently: a smaller operation, rather more willing to build whatever a particular client happened to ask for, before the catalog hardened into a set of fixed configurations. Later references are a great deal more uniform in the options they were ever offered with, and the range of them narrows steadily as the years go on. Whatever the underlying reason, the practical consequence for a collector today is that Octa Chronographes vary in ways that later Journes simply do not, and the dial material is therefore worth establishing specifically on any given example rather than being assumed from the reference number alone.
This is a watch for somebody who collects intersections rather than individual models. Nothing about it is the best example of anything in particular: the chronograph is not the manufacture's most sophisticated, the case is not made from its rarest metal, and yellow gold is emphatically not to everybody's taste. What it is instead is a watch that could only have been made within one very narrow window: when the movements were still brass, the cases were still 38 mm, the chronograph was still in the catalog at all, and somebody was willing to specify a yellow gold plate for it. Verify the brass movement through the caseback before anything else, since that single detail anchors the entire period attribution. Then exercise the chronograph fully, confirming that the hands return exactly to zero and that the flyback resets and restarts in one clean motion, and inspect the yellow gold plate carefully for evenness of tone against the silver subdials. Original papers are worth a great deal more here than they usually are, since they are frequently the only means of dating an early example with any precision.
