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.", "score": 206}, {"slug": "vacheron-constantin-4072", "brand": "Vacheron Constantin", "ref": "4072", "model": "Chronograph", "case_material": "Stainless Steel", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/vacheron-constantin-4072", "description": "Produced from 1938 until the late 1960s, the Vacheron Constantin reference 4072 is a manual-wind chronograph characterized by its 34mm case and square pushers. Collectors prioritize this reference for its balanced aesthetic and the use of high-grade movements, primarily the Valjoux-based Caliber 434 or the earlier Caliber 492. While the model was manufactured in yellow gold, rose gold, and steel-and-gold configurations, the stainless steel variant is the rarest, with fewer than 300 units estimated to have been produced across the entire production run. Dial variations include pulsometric or tachymetric scales and sector layouts. On the secondary market, stainless steel examples typically command between $40,000 and $100,000 depending on condition and dial rarity. A notable auction result occurred in 2022 when a steel example with a silvered sector dial sold for approximately $163,000, reflecting the premium placed on well-preserved steel specimens.", "score": 20}]}
