The Centigraphe measures elapsed time to a hundredth of a second and was invented after a conversation about motor racing. Jean Todt, then running Ferrari's Formula One team, raised the subject with Journe through the ICM foundation, and the watch that resulted in 2007 won the Aiguille d'Or at Geneva the following year. It is operated by a rocker in the case band rather than by pushers, and a share of the profit from every one goes to the ICM, which is a commitment the house has kept without a time limit. This is the boutique execution in 18K 6N gold with a blackened dial, sold only through Journe's own shops and no longer made.
The case is 18K 6N gold at 40 mm, polished, and the detail that defines it is not on the dial at all but on the side: a rocker at two o'clock in the case band, which starts, stops and zeroes the chronograph in place of the two pushers every other maker uses. Pressing a rocker with the thumb while the watch stays on the wrist is a genuinely better arrangement than reaching across a case with a fingertip, and it is patented. The dial is blackened gold with three subsidiary counters in whitened guilloche silver, held by a polished steel ring that frames them as a group rather than letting them float. Against a dark plate those three silver discs are the entire composition. Central hours and minutes run beneath them. A tachymeter scale is printed around the edge, running from walking pace upward, which on a watch of this kind is more a statement of intent than a tool. The rest of the case is conventional Journe. Forty millimeters across, a narrow flat bezel, and a caseband broken only by the crown and the rocker. Sapphire covers both faces, so the chronograph work is visible from behind, sitting above the going train rather than beside it, which is not how a chronograph is usually laid out. The hands are finished to hold against the blackened plate, and the printing is kept to what the scales require and nothing more.
Three counters divide the measurement between them. The hundredth of a second sits at ten o'clock and is a foudroyante, sweeping its own dial once every second, and it can be stopped anywhere along that path, including between two divisions, so a fractional reading is possible. Twenty seconds are counted at two o'clock and ten minutes at six. Each of those hands is driven by its own train, taken directly from the center of the mainspring rather than from the timekeeping gear, which is the arrangement that lets the chronograph run without robbing the going train and which reuses a patent from the Sonnerie Souveraine. That is the reason a hundredth of a second is readable at all without an absurdly fast balance. The chronograph is isolated from the time display entirely. Everything else on the watch is deliberately plain: hours, minutes, and nothing more. Operating it is the part that surprises people. The rocker sits under the thumb when the watch is on the left wrist, so the chronograph can be started and stopped without the other hand and without pushing the case sideways, which is the failure mode of a conventional two-pusher chronograph. Pressing one end starts and stops; pressing the other returns everything to zero. Journe filed patents for the coupling of the hundredth of a second hand and for the way the chronograph draws its energy, and both are the sort of thing that only matters once the watch is in use.
The Centigraphe occupies an odd position in the collection. It is one of the most inventive things Journe has built and one of the least discussed, overshadowed by the Resonance and the tourbillons that carry the brand's reputation. Part of that is the subject matter, since a chronograph is a common complication and the Centigraphe's contribution is invisible until the mechanism is explained. Part of it is that the watch has a public purpose, and pieces attached to a charity tend to be discussed in those terms rather than as watchmaking. The boutique execution narrows an already narrow audience: a gold case, a dark dial, and distribution through the brand's own shops only. Later versions of the Centigraphe followed, including a lighter Sport variant, and the connection to the ICM has continued across all of them. Its standing among collectors has improved slowly rather than suddenly. For years the Centigraphe was the reference people bought after the obvious ones, and it traded quietly while the tourbillons and the Resonance took the attention. That has changed as the mechanism has become better understood, helped by published work on the patents, and the watch now reads as one of the more original chronographs built in the last thirty years rather than as a curiosity. The boutique versions have followed the same path.
This is a watch for someone who wants the mechanism rather than the badge. Nothing about a Centigraphe announces what it does, and the rocker is the only external clue that the case contains anything unusual at all. In gold with a blackened dial the watch reads as a dress chronograph rather than as a sporting one, which suits the layout better than a bright dial does, since three silver counters on a dark plate is the clearest version of the composition. As a discontinued boutique execution the questions are condition and documentation, and the rocker is the part to test, since it is the mechanism most exposed to wear. Papers naming the execution are the only reliable way to establish which version an example is. The chronograph itself should be exercised before any purchase, through several start and stop cycles and a reset, since a foudroyante that hesitates or a zero return that leaves a hand off the mark is a service matter rather than a fault to accept. Beyond that the watch wears easily at 40 mm and does not read as a chronograph from across a table.
