Journe Chronomètre à Résonance in platinum was first introduced in 2000, with the original 38mm reference featuring a brass movement (Calibre 1499) produced until approximately 2004. Subsequent iterations transitioned to 18k rose gold movements (Calibre 1499.2 and 1499.3) and introduced a 40mm case option before the 2020 redesign (Calibre 1520). Collectors prioritize this reference for its dual-balance movement, which utilizes the physical phenomenon of resonance to synchronize two independent oscillators for improved chronometric stability. Early \"Brass Movement\" examples and \"Pre-Souscription\" dials are particularly sought after due to their rarity and significance in the brand's founding era. On the secondary market, prices typically range from $250,000 to over $500,000 depending on the specific generation and dial configuration. A notable auction result occurred in 2023 when a rare 38mm platinum \"Souscription\" model achieved a hammer price exceeding $1,000,000."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "fp-journe-resonance-brass-movement", "brand": "F.P.
