F.P. Journe Centigraphe Souverain Ref. CT Boutique Rose Gold Black Dial

The Centigraphe reads to a hundredth of a second, and Journe built it after conversations with Jean Todt about what a modern chronograph for motorsport should be. It is operated by a rocker on the side of the case rather than pushers. This is the Boutique Edition, sold only through F.P. Journe boutiques, and the black dial matters: before these appeared, black was reserved for the platinum Black Label watches. The variant ran for only a handful of years.

The case is rose gold at 40 mm and unusually thin for a chronograph. The dial is blackened gold, with three whitened guilloché silver counters held under a polished steel ring: a hundredth of a second at the upper left, twenty seconds at the upper right, ten minutes below. Red printing picks out the fast counter, and the polished ring ties the three together into a single reading across the room.
