Collectors value this reference for its fruit-shaped case construction, featuring 18k gold and translucent red guilloché enamel over an engine-turned ground. The movement is a fire-gilded brass verge caliber with a fusee and chain, typical of the Fleurier style intended for export. The white enamel dial includes Roman numerals and gold spade hands, protected by a hinged cover. On the secondary market, these timepieces typically command prices in the mid-five-figure to low-six-figure range depending on enamel preservation. A notable auction result occurred at Christie’s in 2013, where a similar apple-form Bovet realized approximately $150,000. These watches are often found in pairs, as was the custom for the Qing dynasty imperial court, though single examples remain highly sought after for their mechanical and decorative condition."}, "listing_stats": {"count": 1, "median": 14750.0, "low": 14750.0, "high": 14750.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_8447996166323", "title": "Bovet Bovet 19Thirty Great Guilloché Turquoise (Pre-owned)", "brand": "Bovet", "model": "Bovet 19Thirty Great Guilloché Turquoise (Pre-owned)", "reference": "—", "price_usd": 14750.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "collective-horology", "merchant_name": "Collective Horology", "image_url": "https://cdn.shopify.com/s/files/1/0559/0623/8643/files/P1010918.jpg?v=1773338487", "detail_url": "https://mostexpensivewatches.net/listing/h_8447996166323", "buy_url": "https://mostexpensivewatches.net/out/h_8447996166323", "available": false}], "auction_lots": [{"slug": "bovet-663-2014", "brand": "Bovet", "reference": "663", "model": "Apple-Form Verge Watch", "case_material": "18k Gold and Enamel", "hammer_usd": 197000, "year_sold": 2014, "venue": "Christie's Geneva", "lot_summary": "An exceptional 19th-century apple-form watch made for the Chinese market, featuring fine enamel work and a gold case.", "source_url": "https://www.christies.com/en/lot/lot-5790000", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/bovet-663-2014"}]}
