Introduced in 2000, the F.P. Journe Chronomètre à Resonance was the world’s first wristwatch that applied the resonance phenomenon where the movement is equipped with two independent balances, alternatively serving as an “exciter” and “resonator”. When in motion, the balances create the resonance effect and beat in opposition, naturally evening out each other’s discrepancies and thus enhancing its accuracy.

Inspired by the work of the 18th-century master watchmaker Antide Janvier, Journe rose to the challenge in 1983 and created a pocket-watch using the resonance phenomenon, which subsequently led to the birth of the Chronomètre à Résonance dress watch 17 years later.

François-Paul Journe’s take on the Resonance has slowly evolved from a 38mm case to a 40mm case with rose gold movement. Launched in 2010, the present timepiece is part of the third series, bearing an “RT” serial and boasting a refreshed dial, better known amongst collectors as the “Parking Meter” dial for its distinct dual-time layout. This highly coveted variant was in production until 2019, where a digital time display replaced the traditional analogue format on the left, indicating the hours and minutes via two rotating discs on a 24-hour scale.

Offered in excellent overall condition with its original accessories, the present platinum 40mm Chronomètre à Résonance, numbered 177-RT is a phenomenal display of Journe’s mechanical prowess and is a must-have in any collection.
