The Basics
The Chronomètre Optimum symbolises the very essence of precision for a wristwatch endorsing the accomplishment of F.P.Journe chronometric research. 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 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 18ct rose Gold movement reveals, through the sapphire back, a surprising natural dead beat second defined by a seconds circle screwed onto the movement’s bridges.

About F. P. Journe
The F.P.Journe Manufacture was created relying on a unique principle: innovate and uphold, if not out-rival the high standards of Haute Horology. It makes a point of honor to design and manufacture its mechanical watches one by one and in small series. Constantly seeking perfection, the Manufacture is a world in itself, embodying excellence, know-how and innovation, values that are so dear to … enthusiasts of outstanding watches. François-Paul Journe, master-watchmaker, made every effort to verticalize his production and thus offer timepieces with an authentic manufacture caliber. But this success is the result of more than 30 years of research and outstanding watchmaking, as well as 13 years of efforts and daily tireless work to place his Haute Horology manufacture as benchmark among the most prestigious watch companies. In a historic building dating back from 1892, a sacred place of creation, the 2,000 sq m Geneva Manufacture is organised on three floors. Each year no more than 900 precision chronometers are manufactured here, with a team of specialized watchmakers and artisans, proud to work with a creator whose office is also his workbench. This vision of watchmaking without the slightest compromise, that associates mechanical innovation and quest for precision while respecting tradition, gave birth to new mechanisms such as the Chronomètre à Résonance, the Sonnerie Souveraine, the Tourbillon Souverain with remontoire and dead-beat second or the ultra slim Répétition Souveraine. These pieces of watchmaking art earned F.P.Journe the world’s most prestigious horological awards. Thus, the developments of François-Paul Journe, often called the Abraham-Louis Breguet of modern times, are tested one by one in order to check their reliability and are always elaborated through his care, with his magnifying glass on, tweezers, screwdriver and file in his hands. These inventions, with the label Invenit et Fecit engraved on the dials and 18K rose Gold movements – hallmark of authenticity and pledge of quality – remind of the importance of a caliber designed, constructed and assembled solely in the workshops of the Manufacture. As a matter of fact, in the 18th century this inscription used to be engraved on watches manufactured by prestigious French master-watchmakers upon their acceptance by the Royal Academy of Sciences.
