The Chronomètre Optimum is the latest great timepiece of F.P. Journe Haute Horlogerie.
The Chronomètre Optimum encompasses a majority of exceptional components brought together for the first time in one watch:
- Two barrels in parallel to ensure stability of the driving force of the movement made of rose Gold.
- The patented constant-force remontoire balances the driving force applied to the escapement to make it constant.
- The new and patented EBHP (High-Performance Bi-axial Escapement) revolutionary escapement which not only does it function without lubricant, it also has far greater output than the majority of escapements: 50 hours without loss of amplitude.
- The balance with a spiral with Phillips curve to guarantee better equilibrium.
The aesthetics of the hour, minute and small second displays and of the 70-hour power reserve are in perfect harmony with the visible wheel of the constant-force remontoir on the face of the dial.
The back of the movement reveals, through the sapphire back, a surprising natural dead beat second defined by a seconds circle screwed onto the movement's bridges.
The Chronomètre Optimum comes with a 40 or 42 mm Platinum or 18ct red Gold case, with a white Gold or red Gold dial, on a leather strap, Platinum or 18ct red Gold bracelet.
