Pre-Owned and New F.P. Journe Chronomètre à Résonance Watches for Sale

F.P. Journe Chronomètre à Résonance in Dubai

Prestige Calibers offers new and pre-owned F.P. Journe Chronomètre à Résonance watches in Dubai. The watch carries two complete movements side by side in one case. Each has its own balance and escapement, and each shows its own time on its own dial.

How the resonance works

The idea goes back to the coupled-oscillator experiments of Abraham-Louis Breguet. One specialist source explains that the two balances pass tiny vibrations to each other through the main plate. They trade energy and settle into a shared rhythm, so a rate error in one balance is shared by both.

The balances are free-sprung, which means the watch has no regulator. The maker adjusts the rate with weights on the balances. According to a 2003 interview with François-Paul Journe, the two balances must run within 5 seconds a day of each other for resonance to occur.

Two time displays and Calibre 1520

The left dial shows 24 hours and the right dial shows 12 hours. Each dial has its own small seconds, and a power reserve indicator sits at 12 o'clock.

Calibre 1520 is wound by hand and made of 18K rose gold. It has 62 jewels and two remontoirs d'égalité, a device that gives each escapement an even force. The movement beats at 21,600 vibrations per hour. The power reserve is 42 hours in total, and the brand gives an efficient running time of 28 hours, plus or minus 2.
