F.P. Journe Introduces the New Chronomètre à Résonance
Since its launch in 2000, the Chronomètre à Résonance has perhaps become the quintessential F.P. Journe wristwatch. Still the only wristwatch to rely on the principle of resonance – omitting any mechanical means of transmission – the Résonance has been revamped and improved for its 20th anniversary. While the Résonance was powered by essentially the same calibre (the cal. 1499 in several generations) for its first two decades, the new Chronomètre à Résonance is equipped with the brand-new cal. 1520. Several features set the new movement apart from its predecessor, most notably the use of a single barrel and a remontoir d’egalite constant force mechanism in each going train. Initial thoughts Having learnt a little about the new Résonance from hints dropped by Mr Journe in the past, I was looking forward to this – and the watch lives up to expectations. The basics of the new model are no surprise, since Mr Journe had let on that the movement will incorporate his signature remontoir. The upgrades to the new movement are sensible both in terms of function and timekeeping. Relying on a single barrel eliminates the finicky and occasionally unreliable double-barrel winding mechanism of the original movement. But the remontoir installed in each going train is the crucial upgrade as it optimises the going trains before and after the escapement. In the original Resonance movement, both balance wheels oscillate at an identical amplitude at any one time, but the am...
