It is no longer in production. Collectors value this reference for its cushion-shaped 18k white gold case, which measures 40mm by 49.3mm, and its use of the manufacture caliber 2460DT. This self-winding movement features a second time zone sub-dial at 4 o’clock and a day-night indicator at 8 o’clock, all adjustable via the crown. The silvered opaline dial includes blue painted Arabic numerals and leaf-shaped hands. A distinguishing feature of this anniversary edition is the balance cock, which is hand-engraved with a scrolling \"fleurisanne\" motif inspired by a 1755 pocket watch. On the secondary market, this reference typically trades between $25,000 and $35,000. A smaller 37mm version set with diamonds, reference 7805S, was produced concurrently for women."}, "listing_stats": {"count": 3, "median": 9950.0, "low": 5950.0, "high": 17950.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_15587161866623", "title": "Vacheron Constantin Vacheron Constantin Harmony | REF. 61701/940 | Pavé Diamond Dial | 18k Yellow Gold | 19mm | Circa 1980's", "brand": "Vacheron Constantin", "model": "Vacheron Constantin Harmony | REF. 61701/940 | Pavé Diamond Dial | 18k Yellow Gold | 19mm | Circa 1980's", "reference": "61701/940", "price_usd": 17950.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "18k Yellow Gold", "case_size_mm": 19.0, "movement": "Automatic", "complications": [], "merchant_slug": "watch-collectors-uk", "merchant_name": "Watch Collectors UK", "image_url": "https://cdn.shopify.com/s/files/1/0628/2218/7234/files/VacheronConstantinHarmonyVintage18KDiamond_8a64c02a-eb2f-414b-af7f-21886b7999b2.jpg?v=1738859142", "detail_url": "https://mostexpensivewatches.net/listing/h_15587161866623", "buy_url": "https://mostexpensivewatches.net/out/h_15587161866623", "alt_buy_urls": [{"partner": "goldsmiths", "name": "Goldsmiths", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_15587161866623/via/goldsmiths"}, {"partner": "selfridges", "name": "Selfridges", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_15587161866623/via/selfridges"}, {"partner": "farfetch", "name": "Farfetch", "region": "Global", "url": "https://mostexpensivewatches.net/out/h_15587161866623/via/farfetch"}], "available": true}, {"id": "h_14932465287551", "title": "Vacheron Constantin Vacheron Constantin Harmony | REF. 61701/940 | Pavé Diamond Dial | 18k Yellow Gold | Circa 1980's", "brand": "Vacheron Constantin", "model": "Vacheron Constantin Harmony | REF. 61701/940 | Pavé Diamond Dial | 18k Yellow Gold | Circa 1980's", "reference": "61701/940", "price_usd": 9950.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "18k Yellow Gold", "case_size_mm": 19.0, "movement": "Automatic", "complications": [], "merchant_slug": "watch-collectors-uk", "merchant_name": "Watch Collectors UK", "image_url": "https://cdn.shopify.com/s/files/1/0628/2218/7234/files/VacheronConstantinHarmonyVintage18KDiamond_8a64c02a-eb2f-414b-af7f-21886b7999b2.jpg?v=1738859142", "detail_url": "https://mostexpensivewatches.net/listing/h_14932465287551", "buy_url": "https://mostexpensivewatches.net/out/h_14932465287551", "alt_buy_urls": [{"partner": "goldsmiths", "name": "Goldsmiths", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_14932465287551/via/goldsmiths"}, {"partner": "selfridges", "name": "Selfridges", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_14932465287551/via/selfridges"}, {"partner": "farfetch", "name": "Farfetch", "region": "Global", "url": "https://mostexpensivewatches.net/out/h_14932465287551/via/farfetch"}], "available": false}, {"id": "h_8116817854690", "title": "Vacheron Constantin Vacheron Constantin Harmony | REF. 61201/939 | 18k Yellow Gold | 1980's | Quartz", "brand": "Vacheron Constantin", "model": "Vacheron Constantin Harmony | REF. 61201/939 | 18k Yellow Gold | 1980's | Quartz", "reference": "61201/939", "price_usd": 5950.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "18k Yellow Gold", "case_size_mm": 19.0, "movement": "Automatic", "complications": [], "merchant_slug": "watch-collectors-uk", "merchant_name": "Watch Collectors UK", "image_url": "https://cdn.shopify.com/s/files/1/0628/2218/7234/files/1E0A2245.jpg?v=1689351751", "detail_url": "https://mostexpensivewatches.net/listing/h_8116817854690", "buy_url": "https://mostexpensivewatches.net/out/h_8116817854690", "alt_buy_urls": [{"partner": "goldsmiths", "name": "Goldsmiths", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_8116817854690/via/goldsmiths"}, {"partner": "selfridges", "name": "Selfridges", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_8116817854690/via/selfridges"}, {"partner": "farfetch", "name": "Farfetch", "region": "Global", "url": "https://mostexpensivewatches.net/out/h_8116817854690/via/farfetch"}], "available": false}], "auction_lots": [{"slug": "vacheron-constantin-7810s-000g-b050-2024", "brand": "Vacheron Constantin", "reference": "7810S/000G-B050", "model": "Harmony Dual Time", "case_material": "18k White Gold", "hammer_usd": 23940, "year_sold": 2024, "venue": "Christie's Dubai", "lot_summary": "A cushion-shaped dual time wristwatch from the Harmony collection, featuring a day/night indicator and a sophisticated white gold case.", "source_url": "https://www.christies.com/en/lot/lot-6493832", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/vacheron-constantin-7810s-000g-b050-2024"}]}
