chronomètre à résonance françois-paul journe pays tribute to the research conducted on resonance by the great 18th century watchmakers with the presentation of the first wristwatch resonance chronometer first unveiled in the year 2000 this watch represents one of the wildest challenges ever in the field of the mechanical watch using the natural phenomenon of resonance this mechanism revolutionises established standards and offers a previously unmatched degree of precision in mechanical wristwatches the first research on the phenomenon of research in horological science dates back to the 18th century ...

chronomètre à résonance two centuries later françois-paul journe took up the challenge with a first creation in the form of a pocket-watch which did not yet perform according to his expectations it would take fifteen more years of work for the watchmaker to gain the maturity and the experience to enable him to present an exclusive world première the first resonance wristwatch he devised developed and built this movement to meet the demands of actual wear on the wrist and thereby provide chronometric performance driven to extremes each of the two balances alternately serves as exciter and resonator ...

the deadbeat seconds device or the art of making time stand still towards the late 17th century as clocks were becoming increasingly precise watchmakers added a hand finally enabling them to measure seconds these clocks which became pendulum clocks thanks to the invention of the pendular balance by the dutch watchmaker huygens were almost naturally equipped with a 1 metre-long balance with a period of 1 second the dial was marked out into 60 subdivisions so that the hand could jump from one second to the next when the first watches indicating seconds were made some 18th century watchmakers ...

the constant-force device from ancient times humankind has constantly attempted to measure time by dividing it into equal fractions and inventing the notion of isochronism only with the arrival of the first mechanical clocks did specialists begin to seek a means of equalising the force reaching the escapement the balance-spring did not yet exist and the so-called foliot balance had an irregular beat due to the arrival of a force varying because of the imperfections of the gearing at the time clocks were equipped with just one hand which completed a revolution once every 12 hours since their ...

sonnerie souveraine like all movements in chronometers carrying the f.p.journe ­ invenit et fecit ­ signature the plate and the bridges of the mechanism are in 18-carat pink gold while the case with its diameter of 42 mm and a thickness of 12.30 mm is paradoxically in steel exceptionally the watchmaker has abandoned precious metals such as gold and platinum for a noble cause to ensure the best possible striking tone for this spectacular creation that makes optimal use of the crystalline structure of steel françois-paul journe remains faithful to his motto innovating in horological science while ...
