Representing the height of F.P. Journe's precision research, the Chronomètre Optimum utilizes a titanium constant-force remontoire (patent EP1528443.A1) to stabilize energy delivery to the escapement. It incorporates the patented, oil-free EBHP High-Performance Bi-axial Escapement (patent EP11405210.3), which offers superior efficiency and self-starting capabilities. The 18ct rose gold movement, visible through the sapphire back, includes a natural dead beat second, complemented by a dial layout that integrates the power reserve and remontoire wheel.
