The first-generation Chronomètre à Résonance, housed in a 38mm case with a brass movement, draws inspiration from the pioneering work of 18th-century master watchmaker Antide Janvier. In 1983, François-Paul Journe set out to honor Janvier’s legacy by crafting a pocket watch that harnessed the resonance phenomenon. Sixteen years later, he introduced his now-iconic Chronomètre à Résonance wristwatch—the first of its kind to incorporate this remarkable principle.

At the heart of this groundbreaking timepiece lies a movement featuring two independent balance wheels, one acting as the "exciter" and the other as the "resonator." When in motion, these balances synchronize through resonance, naturally counterbalancing each other’s deviations to enhance precision.

Produced between 2000 and 2005, the first-generation Chronomètre à Résonance (reference R), like the present example, featured a rhodium-plated brass movement within its 38mm case.

According to reliable sources, approximately 70–80% of the -02 Résonance production was cased in platinum, making examples in pink gold extremely scarce. Even rarer is the striking combination of a pink gold case with a white gold dial. Numbered 178-02R, it is fresh-to-the market and offered complete with all its original accessories.
