The Chronomètre Optimum was first conceived as an idea in 2001; however, the first example was not released until 2012. A showcase of watchmaking excellence and innovation, it adopts concepts from other Journe models: the double barrel layout of the Chronomètre Souverain, and the remontoir d'égalité system and hairspring with Breguet overcoil of his tourbillon wristwatch. The Optimum is to be considered Journe’s “ultimate” technical essay on precision, reuniting the most efficient chronometer solutions from previous models, and then adding to them a new escapement of Journe’s design.

The solid 18K pink gold movement features indeed Journe’s patented ‘BHP’ - Bi-axial Hi Performance - escapement. Inspired by works of Abraham-Louis Breguet, this natural escapement employs two escapement wheels (thus, Bi-axial) rather than the usual single one. This solution, coupled with special design geometries, allows for the escapement to function without lubrication and ensures more reliability overall and reduced wear and tear. The remontoir d'égalité system, escape wheels, and pallet fork are made from lightweight titanium further enabling greater timekeeping precision. An additional dead-beat seconds indicator, connected to the remontoir, is displayed on the backside of the movement.

Preserved in like new condition with all original accessories, the present Chronomètre Optimum in platinum with white gold dial measures 42mm and dates to 2015.
