F. P. Journe has unveiled the new Chronomètre Optimum, as part of The Souveraine collection of haute horlogerie. The double barrel with its two springs ensures stability of the driving force, with a movement made of 18ct rose gold, a trademark 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 with 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. The escapement also offers 50 hours of output 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 improves equilibrium.
The Chronomètre Optimum features two barrels in parallel, a constant-force remontoire, a new EBHP revolutionary escapement, and a natural dead beat second. The aesthetics of the hour, minute and small second displays and the 70-hour power reserve echo the visible wheel of the constant-force remontoir on the face of the dial. The back of the 18ct rose Gold movement reveals, through the sapphire back, a 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.
