Collectors prioritize this reference for its solid gold construction and the Valjoux 72 manual-wind movement, a column-wheel caliber shared with contemporary high-end chronographs. The 36mm case features the signature long, faceted lugs characteristic of early Carreras, typically paired with a silvered sunburst dial and applied gold markers. Due to the high cost of gold at the time, production numbers were significantly lower than steel counterparts, making well-preserved examples rare. On the secondary market, prices generally range from $15,000 to $25,000 depending on the presence of original hallmarks and dial condition. A notable variant includes the 2456S, which features a tachymeter scale printed on the inner tension ring, a detail that often commands a premium at specialized watch auctions.", "score": 199}]}
