Collectors prioritize this reference for its 39mm \"Jumbo\" case profile and the ultra-thin caliber 2120/2800, which lacks a leap year indicator on the dial. Unlike modern iterations, the 25654ST features a smooth, non-tapisserie dial, often found in silver or blue, and a closed caseback. Its historical significance lies in its role as a transitional model that maintained the original Genta proportions while housing a complex complication. Secondary market prices typically range from $120,000 to $180,000 depending on condition and provenance. A notable variant includes the \"Yves Klein\" blue dial, which commands a significant premium at auction. Production records indicate that while 800 total units were planned across all metals, the steel version remains the most sought-after for its utilitarian aesthetic.", "score": 202}]}
