Collectors prioritize this reference for the Calibre 1120 QPSQ/1, a skeletonized, self-winding movement measuring 4.05mm thick within an 8.1mm pink gold case. The open-worked dial features 18k pink gold hour markers and circular-grained finishes, maintaining a 50-meter water resistance rating despite its slim profile. It includes the brand’s proprietary interchangeable strap system with a gold bracelet, rubber, and leather options. On the secondary market, this model typically trades in the $140,000 to $180,000 range, though prices fluctuate based on inventory. A notable production detail is its 2020 Grand Prix d’Horlogerie de Genève (GPHG) win in the Calendar and Astronomy category, which solidified its status as a technical benchmark for the Overseas collection."}, "listing_stats": {"count": 2, "median": 125500.0, "low": 115000.0, "high": 136000.0, "brands": 1, "merchants": 2}, "listings": [{"id": "h_7700667859153", "title": "Vacheron Constantin Vacheron Constantin Overseas Perpetual Calendar 4300V/000R-B509", "brand": "Vacheron Constantin", "model": "Vacheron Constantin Overseas Perpetual Calendar 4300V/000R-B509", "reference": "4300V/000R-", "price_usd": 115000.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "18k Rose Gold", "case_size_mm": 41.5, "movement": "Automatic", "complications": ["Perpetual Calendar"], "merchant_slug": "material-good", "merchant_name": "Material Good", "image_url": "https://cdn.shopify.com/s/files/1/0561/5190/0369/files/IMG_2167.jpg?v=1771006702", "detail_url": "https://mostexpensivewatches.net/listing/h_7700667859153", "buy_url": "https://mostexpensivewatches.net/out/h_7700667859153", "alt_buy_urls": [{"partner": "goldsmiths", "name": "Goldsmiths", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_7700667859153/via/goldsmiths"}, {"partner": "selfridges", "name": "Selfridges", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_7700667859153/via/selfridges"}, {"partner": "farfetch", "name": "Farfetch", "region": "Global", "url": "https://mostexpensivewatches.net/out/h_7700667859153/via/farfetch"}], "available": true}, {"id": "h_7156159905875", "title": "Vacheron Constantin Overseas Perpetual Calendar Ultra-Thin Skeleton | 4300V | Rose Gold", "brand": "Vacheron Constantin", "model": "Overseas Perpetual Calendar Ultra-Thin Skeleton | 4300V | Rose Gold", "reference": "4300V", "price_usd": 136000.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "18k Rose Gold", "case_size_mm": 40.0, "movement": "Automatic", "complications": ["Perpetual Calendar", "Skeletonized"], "merchant_slug": "a-collected-man", "merchant_name": "A Collected Man", "image_url": "https://cdn.shopify.com/s/files/1/0606/5325/files/6165f6cecdf7bb3085b83efc5487b3d8_48062ff0-aaf1-4571-85d3-c8f40d0a0baa.jpg?v=1708088401", "detail_url": "https://mostexpensivewatches.net/listing/h_7156159905875", "buy_url": "https://mostexpensivewatches.net/out/h_7156159905875", "alt_buy_urls": [{"partner": "goldsmiths", "name": "Goldsmiths", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_7156159905875/via/goldsmiths"}, {"partner": "selfridges", "name": "Selfridges", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_7156159905875/via/selfridges"}, {"partner": "farfetch", "name": "Farfetch", "region": "Global", "url": "https://mostexpensivewatches.net/out/h_7156159905875/via/farfetch"}], "available": false}], "auction_lots": [{"slug": "vacheron-constantin-4300v-120r-b547-2022", "brand": "Vacheron Constantin", "reference": "4300V/120R-B547", "model": "Overseas Perpetual Calendar Ultra-Thin Skeleton", "case_material": "18k Pink Gold", "hammer_usd": 265000, "year_sold": 2022, "venue": "Sotheby's Geneva", "lot_summary": "A skeletonized version of the ultra-thin perpetual calendar, this model features the automatic Caliber 1120/1 and a translucent moon phase display.", "source_url": "https://www.sothebys.com/en/articles/the-five-most-expensive-vacheron-constantin-overseas-watches", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/vacheron-constantin-4300v-120r-b547-2022"}, {"slug": "vacheron-constantin-4300v-120g-b945-2022", "brand": "Vacheron Constantin", "reference": "4300V/120G-B945", "model": "Overseas Perpetual Calendar Ultra-Thin", "case_material": "18k White Gold", "hammer_usd": 153000, "year_sold": 2022, "venue": "Sotheby's Hong Kong", "lot_summary": "This white gold model features a striking sunburst blue lacquered dial and houses the ultra-thin Caliber 1120 QP/1.", "source_url": "https://www.sothebys.com/en/articles/the-five-most-expensive-vacheron-constantin-overseas-watches", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/vacheron-constantin-4300v-120g-b945-2022"}, {"slug": "vacheron-constantin-4300v-120g-b102-2021", "brand": "Vacheron Constantin", "reference": "4300V/120G-B102", "model": "Overseas Ultra-Thin", "case_material": "18k White Gold", "hammer_usd": 81900, "year_sold": 2021, "venue": "Sotheby's New York", "lot_summary": "Released in 2018, this understated perpetual calendar model features a grey dial and white gold case, powered by the automatic Caliber 1120/3.", "source_url": "https://www.sothebys.com/en/articles/the-five-most-expensive-vacheron-constantin-overseas-watches", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/vacheron-constantin-4300v-120g-b102-2021"}]}
