- Page 2 Preface Chronomètre à Résonance An emblematic timekeeper_ With the invention of the pendulum, watchmakers noticed that their beat often interfered with the environment and it was not unusual for a pendulum clock to stop, on its own, when it entered into resonance with the driving-weight hanging from the cords. The first to get the feeling that one might turn this disadvantage into an asset was Antide Janvier, a particularly brilliant watch- maker or “mechanical engineer”...
- Page 3 What is the resonance phenomenon? Two frequencies which get into harmony_ Any animated element transmits a vibration to its environment. When another element picks up this vibration, it absorbs its energy and begins to vibrate at the same frequency. The first is called the “exciter” and the second the “resonator”. This physical phe- nomenon known as “resonance”...
- Page 4 Biography Antide Janvier French master watchmaker, 1751—1835 Antide Janvier is one of the most renowned French watchmakers. He created many horological masterpieces, in particular celestial spheres and planetariums with astronomical indications. Antide Janvier was born on July 1 , 1751 in Briva, near Saint-Claude. He was the son of Claude-Etienne Janvier, a farm plough- man who gave up his plough to dedicate himself to clock making.

- Page 7 Préface Tourbillon Souverain À la conquête de la précision_ He remained close to the King and spent many late evenings observing the satellites of Jupiter and other celestial objects with him. In 1792, he presented his Geographic clock to the Queen, tactlessly telling her Majesty: “You see, you can tell the time anywhere;...
- Page 8 In 2004, F.P. Journe introduced a second version of the Chronomètre à Résonance with the introduction of the first movement ever made in 18K rose Gold, a specification that, from then on, applied to all the precision chronometers of the brand.
- Page 10 Operating instructions Tourbillon Souverain À la conquête de la précision_ Crown_ Winding : Keep the crown on position 1 and turn forwards until it stops. The Chronomètre à Résonance features an efficient power reserve of 42 hours. It can nonetheless beat above these 42 hours but in this case, the watch needs to be completely wound until it stops, in order to gain back the total strength of the spring.

- Page 12 Characteristics Chronomètre à Résonance Mechanism Patented system_ The Chronomètre à Résonance features two specific balances with four long inertia weights for the setting of advance and delay. They have been set in our engineering workshops to beat to a frequency of 21’600 v/h. The two balances enter in sympathy thanks to the resonance effect and naturally begin to beat in opposition.
