F.P. Journe Chronomètre à Résonance

About this reference

The F.P. Journe Chronomètre à Résonance RT (Reference RT) was produced between approximately 2010 and 2019. This reference is distinguished by its 40mm or 38mm case construction, often pairing a platinum or 18k pink gold exterior with an 18k rose gold movement, specifically the Calibre 1499.3. Collectors prioritize this model for its use of physical resonance, where two independent balance wheels synchronize to improve chronometric stability. The RT generation introduced a digital 24-hour disc at the 24-hour sub-dial, replacing the analog hands found on earlier versions. On the secondary market, these pieces typically trade in the mid-to-high six-figure range, often between $250,000 and $450,000 depending on metal and dial configuration. A notable production detail is the transition from the 38mm to 40mm case size during this period, with the smaller 38mm variants often commanding a premium due to lower production volumes.
