Collectors target this reference for its 40mm case diameter and slim 6.79mm profile, which utilizes a two-part construction with a solid caseback to maintain structural rigidity. It is powered by the manual-wind Calibre 1400, an in-house movement bearing the Hallmark of Geneva. The dial features a silvered opaline finish with applied 18k gold hour markers and a \"pearl\" minute track composed of polished gold spheres. On the secondary market, this white gold model typically trades between $12,000 and $16,000 depending on the presence of original documentation. A notable production detail is the absence of a seconds hand or date window, a design choice intended to preserve the visual symmetry favored by purists of the minimalist dress watch genre."}, "listing_stats": {"count": 2, "median": 14087.5, "low": 12345.0, "high": 15830.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_7077850579019", "title": "Vacheron Constantin Vacheron Constantin Patrimony 81180", "brand": "Vacheron Constantin", "model": "Vacheron Constantin Patrimony 81180", "reference": "81180", "price_usd": 15830.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "hodinkee", "merchant_name": "Hodinkee Shop", "image_url": "https://cdn.shopify.com/s/files/1/0146/0732/files/Vacheron-Constantin-Patrimony-81180-10-21-VAC-EK6RKS-3cc79834bfc0.jpg?v=1714573421", "detail_url": "https://mostexpensivewatches.net/listing/h_7077850579019", "buy_url": "https://mostexpensivewatches.net/out/h_7077850579019", "alt_buy_urls": [{"partner": "goldsmiths", "name": "Goldsmiths", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_7077850579019/via/goldsmiths"}, {"partner": "selfridges", "name": "Selfridges", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_7077850579019/via/selfridges"}, {"partner": "farfetch", "name": "Farfetch", "region": "Global", "url": "https://mostexpensivewatches.net/out/h_7077850579019/via/farfetch"}], "available": false}, {"id": "h_7076933664843", "title": "Vacheron Constantin Vacheron Constantin Patrimony 81180/000J", "brand": "Vacheron Constantin", "model": "Vacheron Constantin Patrimony 81180/000J", "reference": "81180/000J", "price_usd": 12345.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "hodinkee", "merchant_name": "Hodinkee Shop", "image_url": "https://cdn.shopify.com/s/files/1/0146/0732/files/Vacheron-Constantin-Patrimony-81180-000J-10-21-VAC-2V2PWB-c45c65ef99e9.jpg?v=1714512447", "detail_url": "https://mostexpensivewatches.net/listing/h_7076933664843", "buy_url": "https://mostexpensivewatches.net/out/h_7076933664843", "alt_buy_urls": [{"partner": "goldsmiths", "name": "Goldsmiths", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_7076933664843/via/goldsmiths"}, {"partner": "selfridges", "name": "Selfridges", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_7076933664843/via/selfridges"}, {"partner": "farfetch", "name": "Farfetch", "region": "Global", "url": "https://mostexpensivewatches.net/out/h_7076933664843/via/farfetch"}], "available": false}], "auction_lots": [{"slug": "vacheron-constantin-81180-2014", "brand": "Vacheron Constantin", "reference": "81180", "model": "Patrimony Grande Taille", "case_material": "18k White Gold", "hammer_usd": 7500, "year_sold": 2014, "venue": "Christie's New York", "lot_summary": "A modern 40mm dress watch inspired by the minimalist designs of the 1950s, featuring a clean silvered dial and ultra-thin profile.", "source_url": "https://www.christies.com/en/lot/lot-5805101", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/vacheron-constantin-81180-2014"}]}
