Journe Centigraphe Souverain Sport reference 072-CTS was produced between 2011 and 2014 as part of the LineSport collection. This reference is distinguished by its 42mm case, bracelet, and manual-wind caliber 1506 movement all crafted from an aluminum alloy, a departure from the brand’s typical use of precious metals. Collectors value the 072-CTS for its lightweight construction, weighing approximately 55 grams, and its high-frequency chronograph capable of measuring 1/100th of a second. The movement features a patented mechanism that isolates the chronograph from the timekeeping gear train to maintain amplitude. On the secondary market, this reference typically trades in the mid-to-high six-figure range. A notable production detail is the transition from the aluminum caliber 1506 to titanium in later LineSport models, making the aluminum version a specific four-year production window rarity within the brand's history."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "f-p-journe-072-cts-2021", "brand": "F.P.
