In 2004, Journe, the brand,
began manufacturing movements from 18-carat gold, having developed the brand sufficiently to further the manufacturing process. The Chronomètre à Résonance
in this example is comprised of two balance wheels, inspired by a natural phenomenon called resonance. The complication is explained by François-Paul thusly;
“In a watch, never mind which, there is energy which dissipates. When you listen to a watch, the tic-tac of the balance is dissipating energy. In a resonance chronometer, there are two balance wheels which are placed sufficiently close to one another, and the dissipated energy of each is caught by the other, leading to a unique type of frequency regulation.”
The discovery is said to have been made in 1665, by Dutch mathematician Christiaan Hygens, who reported that two pendulum clocks, hanging from the same mounting beam, would beat in such perfect duplicity, that the sound of the escapements were indistinguishable from one another. The concept was later researched and developed by Antide Janvier, to be refined by Abraham-Louis Breguet. Early sceptics suggested that air-resistance played a role, however, extensive testing by Breguet (the first to test a dual-train resonance watch with a double-balance system, placing rings around the balance wheels, to negate the effects of air), and more recently by François-Paul
, proved this to be untrue. Whilst the concept was long established, the term ‘resonance’ was in fact coined by Monsieur Journe himself, likening the phenomenon to that of a stringed musical instrument, which resonates.
The Chronomètre à Résonance
is quintessentially an F.P Journe
, in both its design language and movement. Housed in a classical 40mm dress watch case, it is made distinctive by F.P. Journe
’s signature ‘flat crown’ with a rope-like pattern. The rose-gold dial is delicately textured, and displays two separate silver guilloché dials for the hours and minutes (the two opposing dials capable of displaying multiple time zones). The words ‘Invenit et Fecit’ are inscribed below the two subsidiary seconds (Latin for 'Invented and Made') in classic F.P Journe
style - a nod to signing conventions of a century ago. The signature hands form a distinct contrast to the silver and red/orange dial. At 12 o’clock is a power reserve indicator of 40 hours. Overall, the dial layout is clean and highly legible.
Interestingly, the power reserve indicator of this Chronomètre à Résonance
is reversed from the norm, beginning at 40 and progressing to 0. This was deliberate by F.P. Journe
, who borrowed this from marine chronometer clocks. The reasoning behind this lies in the idea that the power reserve indicator of the Chronomètre à Résonance
is not meant to display how many hours are left, but instead how many hours have passed since the watch was wound.
This manual-winding, F.P. Journe
movement is 18k rose-gold, with fausses-côtes embellishments, constructed with 36 jewels. It features a resonance-controlled, twin independent gear-train, straight-line lever escapement, monometallic 4-arm balance with 4 timing weights, self-compensating free-sprung flat balance spring, oscillating at a rate of 21,600 vibrations per hour. Further to this, a winding crown at 12 o’clock adjusts both time-zones, with a crown at 4 o’clock to synchronize the seconds’ hands.
The earliest works of François-Paul Journe, effortlessly blend traditional 19th-century watchmaking with modern haute-horology. Housed in a 40mm platinum case, this F.P. Journe Chronomètre à Résonance
represents a modern take on Journe's original, inspired design. Monsieur Journe’s mastery is evident in the look, feel, and romance of his craftsmanship - inspired by his immediate works after graduation, restoring 18th and 19th century marine chronometers and pocket watches.
This pre-owned watch was never worn by its original owner, thus is preserved in mint condition. It comes as full-set, with its original box and Certificate of Origin.
It comes with an original black F. P Journe
alligator strap, and corresponding platinum tang buckle.
