F.P. Journe Chronomètre À Résonance Ref. RT Boutique Rose Gold Black Dial

Boutique dials are the only place the reworked Résonance appears in black, and the combination sits oddly against a watch whose whole point is symmetry. Two displays on a dark ground read as a pair of holes cut into the face until the light catches the guilloché underneath them. Rose gold warms it enough to keep the effect from turning severe, and the black keeps a busy face under control. Nothing about the combination was ever offered publicly.

The case is rose gold, at 40 or at 42 mm. A blackened gold plate holds both displays in whitened guilloché silver, with a seconds hand on each side, which the earlier versions of the model did without. Nothing on the dial indicates that two movements are running behind it and influencing one another. The two displays can be set apart to carry a second time zone, which is how most owners use it.
