Ninety-nine pieces of each model, five models in all, and one metal that essentially nobody else in the industry was using. The Ruthenium series is among the most closely watched things F.P. Journe has done, and this Octa Calendrier is one of the five references that made it up, alongside the Octa Jour et Nuit, the Octa Chronographe, the Chronometre a Resonance and the Tourbillon Souverain. Built between 2001 and 2003, the series marked the first time the manufacture applied ruthenium to both the dial and the movement plates, and the platinum case here measures 40 mm, which was larger than the 38 mm that was standard for a complicated Journe at the time. The dial combines ruthenium on gold with whitened guilloche silver, and the watch shows off-center hours and minutes, small seconds at 4:30, a large central date, and the day and month in windows.
Ruthenium is a peculiar choice of material and is worth explaining properly. It is a member of the platinum group, extremely hard, extremely resistant to corrosion, and almost never used in watchmaking, both because it is difficult to work with and because it produces a color most manufactures would politely call indeterminate: a dark, cool gray carrying a faint blue cast, which reads differently under daylight than it does under artificial light and refuses to photograph with any consistency at all. Journe applied it over gold on the dial, so that the surface carries the hardness and the tone of ruthenium over a precious base rather than over brass, and he paired that treatment with whitened guilloche silver for the remaining areas of the face. The resulting combination is deliberately unsettled, and it was very clearly meant to be. Against the gray of a platinum case the ruthenium reads darker and cooler still than it otherwise would, and the whitened silver ends up supplying the only genuinely bright element anywhere on the watch. At 40 mm the case was a genuine departure at the time it appeared, and it now reads as entirely ordinary, which is a useful reminder of how far the industry moved in the two decades that followed. The watch did not change; everything around it did.
Two hundred and forty-one parts produce this calendar, which is fewer than the Automatique Reserve requires for nothing more than a date and a power reserve, and the reason behind that is genuinely instructive. The Calendrier carries no power reserve indication at all. Journe had in hand a movement capable of running for five days, and a dial already showing the time, the seconds, the date, the day and the month, and he simply declined to add a sixth display telling the owner how much winding remained in the barrel. Something had to give way on a face already this busy, and what gave way was the one indication least connected to the actual purpose of the watch. That is a choice most manufactures would have made the other way round, since a power reserve indication is easy to market and an annual calendar is decidedly not, and it is entirely characteristic of a house that has consistently allowed the design to decide rather than the specification sheet. The calibre 1300.3 underneath measures 30.80 mm across and 5.80 mm thick, runs at 21,600 alternations per hour with a mainspring a meter in length, and holds about 160 hours of autonomy, of which the first 120 are underwritten as chronometric running.
The Ruthenium series occupies a very precise position in the manufacture's history, and it was in all likelihood intended to occupy it. Journe built his early movements in brass, as everyone in the industry does, and switched the whole catalog over to solid 18K rose gold around 2004; the Ruthenium watches were made in the two or three years immediately preceding that change, which places them right at the very end of the brass era and just short of the gold one that came after it. They function as a bookend on the whole of that period, closing it deliberately rather than by accident. A collector assembling a chronological view of the manufacture tends to treat them as the closing statement of that first period, and the ruthenium treatment itself, applied to plates that would shortly stop being made in brass at all, lends them a finality that was not necessarily planned at the point the series was announced. Ninety-nine of each across the five models comes to fewer than five hundred watches in total, and set against a manufacture that now produces roughly 900 in a year, the entire series amounts to something in the region of six months of present-day output.
This is a watch for the collector who is interested in where the manufacture came from rather than in what it happens to be making now. The Ruthenium series is unusually well documented and closely tracked, so provenance on any given example is generally establishable, and the numbers involved are small enough that examples tend to be known individually rather than merely statistically. Anyone buying should confirm the ruthenium treatment on both the dial and the movement plates, since that particular combination is precisely what defines the series, and a watch carrying only one of the two treatments is something else entirely. Check the whole dial surface very carefully under good light for any wear through the ruthenium layer, which cannot afterward be reapplied to match the original. Then run the calendar forward through a thirty-day month in order to confirm that it advances to the first entirely unaided, verify that both the day and the month windows step cleanly rather than sticking or lagging behind, and treat the original documentation as absolutely central on a series that has been catalogued this closely.
