Collectors prioritize this reference for its 18k yellow gold case, which features a tiered, gadrooned construction mimicking the organic texture of bamboo. Measuring approximately 27mm by 36mm, the \"Jumbo\" designation distinguishes it from smaller ladies' versions of the era. It typically houses the manual-wind Caliber 2512 and features a white dial with Roman numerals and a \"Paris\" or \"London\" signature. Due to limited production runs, these pieces are rare on the secondary market, with prices generally ranging from $25,000 to $45,000 depending on provenance and condition. A notable auction result occurred in 2023 when a well-preserved example sold for approximately $44,000, reflecting increased demand for non-tank shaped vintage Cartier geometry."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "cartier-78102-2025", "brand": "Cartier", "reference": "78102", "model": "Coussin Bamboo Jumbo", "case_material": "18k Yellow Gold", "hammer_usd": 177800, "year_sold": 2025, "venue": "Phillips New York", "lot_summary": "A world record for the reference in yellow gold, this 1978 'Jumbo' model features a distinctive bamboo-style stepped case.", "source_url": "https://www.phillips.com/detail/cartier/NY080125/38", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/cartier-78102-2025"}]}
