Journe Chronomètre Bleu (Reference CB) entered production in 2009 and remains a catalog piece, though annual output is strictly limited. Collectors prioritize this reference for its 39mm case constructed from tantalum, a rare, dense, and hard-to-machine refractory metal with a distinct blue-grey luster. It houses the manual-wind Calibre 1304, a movement manufactured from 18k rose gold featuring twin barrels and a 56-hour power reserve. The dial is characterized by a chrome-blue finish achieved through multiple layers of lacquer and polishing, paired with cream-colored Arabic numerals and tapered hands. While the original retail price was approximately $20,000, secondary market values currently fluctuate between $75,000 and $100,000. A notable production detail is the \"Byblos\" limited edition of 50 pieces, which features an open-worked dial and was released in 2014 to commemorate the opening of the Beirut boutique."}, "listing_stats": {"count": 1, "median": 449500.0, "low": 449500.0, "high": 449500.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_7783833305175", "title": "F.P.
