Masterpiece of the collection Classique, the Chronomètre Optimum
joins the iconic timepieces of Haute Horology

Combining a rich knowledge of the history of time with modern technologies and the example set by the great masters, the Chronomètre Optimum most certainly joins the great iconic timepieces of F.P.Journe Haute Horology, in an ongoing quest for precision, innovation and excellence. The Chronomètre Optimum symbolises the very essence of precision for a wristwatch endorsing the accomplishment of F.P.Journe chronometric research.The double barrel with its two springs ensures the stability of the driving force of this emblematic movement made of 18ct rose Gold, a specificity of the brand.

The constant-force remontoire (patent EP1528443.A1) balances the driving force applied to the escapement to make it constant. By adding an extra gear representing an independent system wound in short spurts by the mainspring, the escapement ensures the balance’s isochronism. This remontoire, made of titanium for the first time, maintains its balance in different positions, for greater efficiency.

The EBHP High-Performance Bi-axial Escapement has also been patented (patent EP11405210.3). This two-wheel direct impulse escapement functions without oil and is the only direct impulse escapement to start up on its own. But not only does it function without lubricant, it also has far greater output than the majority of escapements: 50 hours without loss of amplitude. Many dual-wheel escapements have been created in the past, the most efficient being the “natural” escapement invented by A-L. Breguet (†1823).

The balance with a spiral with Phillips curve guarantees better equilibrium.
