{"product_id":"chronometre-a-resonance-rn-rose-gold","title":"Chronomètre à Résonance | RN | Rose Gold","description":"\u003cp\u003eThis classic Chronomètre à Résonance* is a quintessential F. P. Journe piece, a brilliant showcase of the watchmaker's work with the phenomenon of acoustic resonance in a wristwatch. This is a particularly rare and attractive example which makes use of the transitional calibre 1499.2, a movement variant believed to have been produced for only around a year. It is further distinguished by its silvery sub-dials, which appear notably more pronounced than the whiter sub-dials typically found on other examples.\u003c\/p\u003e\n\u003c!-- SECTION BREAK --\u003e\n\u003cp\u003eThe Chronomètre à Résonance movement in this example is comprised of two balance wheels, inspired by a natural phenomenon called resonance. The term 'resonance' was coined by Journe, likening the phenomenon to that of a stringed musical instrument, which resonates. He explains the principles behind this complication: “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.”\u003c\/p\u003e\n\u003cp\u003eJourne had previously attempted to put this complication into a pocket watch in 1983, but was unsuccessful. Journe was able to hone the phenomenon of acoustic resonance in a wristwatch some fifteen years later, with the prototypes displayed at his first Basel Fair in 1999. Ever since, the model has gained a cult status among collectors. As Rexhep Rexhepi, an independent watchmaker who previously worked for Journe, put it:\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cblockquote\u003e\n\u003cp\u003e\u003cem\u003e“When I think of Francois-Paul Journe, I think of the Resonance.”\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/blockquote\u003e\n\u003cp\u003eHoused in a classical 40mm case, it is made distinctive by F. P. Journe’s signature elements such as the rope patterned crown. The rose-gold dial is delicately textured, and displays two separate distinctive silver guilloché dials for the hours and minutes (the two opposing dials capable of displaying multiple time zones). Notably, the dials are appearing more silver in tone, rather than the whiter examples typically fitted to these pieces.\u003c\/p\u003e\n\u003cp\u003eThe words ‘Invenit et Fecit’ are inscribed below the two subsidiary seconds (Latin for ‘Invented and Made’ or more literally 'Designed and built by F. P. Journe') in classic F. P. Journe style - a nod to signing conventions of a century ago. A power reserve is shown at 12 o'clock, and is reversed, beginning at 40 and moving toward 0. This was a deliberate choice on Journe's part, as he borrowed this idea from marine chronometer clocks, with the power reserve showing how many hours have passed since the watch was wound instead of how many hours are left. The signature hands form a distinct contrast to the silver and rose-gold dial.\u003c\/p\u003e\n\u003cp\u003eIn around 2004, the brand retired the brass movements that marked its earliest years in favour of those crafted from 18 carat gold. This was also true of the Chronomètre à Résonance, with the brass calibre 1499 giving way to the solid gold version designated calibre 1499.2. These were fitted to the updated reference Resonance Nouveau (RN).\u003cbr\u003e \u003cbr\u003eThe RN used two movements – the calibre 1499.2 would give way to the 1499.3 (with improved power-reserve). The 1499.2 is understood to have been made for a brief period around 2005 to 2006. As a result, examples powered by the calibre 1499.2 are more of a rarity than even the first generation, brass-movement pieces.\u003c\/p\u003e\n\u003cp\u003eThe calibre features horizontal striping and edges adorned with anglage, while the baseplate is decorated with perlage. The movement features 36 pivot jewels for the twin gear train. It has a straight-line lever escapement, monometallic four-arm balance with four timing weights, self-compensating free-sprung flat balance spring oscillating at a rate of 21,600 vibrations per hour.\u003c\/p\u003e\n\u003cp\u003eThe Chronomètre à Résonance is perhaps the most consequential watch F. P. Journe has produced. It wears the weight of the history that informs it lightly, fitting it in proportions suited to contemporary preferences. The Résonance Nouveau follows in this trajectory, both in its proportions and the updated solid gold calibre 1499.2, while the use of silver-toned sub-dials is also noteworthy, as the combination of features makes this especially unusual. The limited production period of this particular item is also a collectible detail. \u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eIf sold within the United Kingdom, this F. P.
