The first Chronomètre Optimum Black Label to be offered at Phillips, the present example is confirmed by F.P. Journe as being one of only two Black Label pieces produced for the Hong Kong boutique in 2015.

The Chronomètre Optimum was first conceived as an idea in 2001, however the first example was not released until 2012. Adopting concepts from other Journe models, like the double barrel layout of the Chronomètre Souverain, and the rementoir d'egalité system of his Tourbillon wristwatch, the Optimum is Journe’s “ultimate” chronometer operating with the least amount of friction to maintain “optimum” chronometric performance over years of use.

The solid 18 karat pink gold movement features a patented ‘EBHP’ direct impulse escapement with a bi-axial design, and remontoire for accuracy and constant force. The movement functions without lubrication, and the two escape wheels allow for lower impact during the transfer of energy, which over time ensures more reliability and less wear. The remontoir d'egalité system is made from lightweight titanium and connected to the additional dead-beat seconds indicator displayed on the backside of the movement. The movement is capable of 70-hours of power reserve when fully wound, with 50 hours possible without loss of amplitude.

Manufactured in pink gold and platinum, as well as in 40mm and 42mm case diameters, the Chronomètre Optimum is a technical marvel that Journe believes will continue to keep accurate time for hundreds of years with proper care and maintenance. Originally offered only to the brand’s best clients, this 40mm, platinum, and extremely limited Black Label example is surely one of the rarest and most exciting iterations. Further enhancing its appeal, it is presented with its original guarantee and accessories.
