Collectors prioritize this reference for its hand-applied cloisonné enamel dial, which depicts the continents of Europe, Africa, the Americas, and Oceania. Unlike the standard 5130, the 5131 features the Patek Philippe name and city names engraved directly onto the gold bezel rather than printed on the dial. It is powered by the ultra-thin caliber 240 HU automatic movement with a 22k gold micro-rotor. Due to the difficulty of the enameling process, production was limited to very few pieces annually, and the reference was never available through standard retail channels without application. On the secondary market, the 5131G typically trades in the $110,000 to $140,000 range. A notable production detail is that each enamel dial varies slightly in color and layout due to the artisanal firing process."}, "listing_stats": {"count": 1, "median": 88000.0, "low": 88000.0, "high": 88000.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_6864494329939", "title": "Patek Philippe World Time | Ref. 5131G-010 | White Gold", "brand": "Patek Philippe", "model": "World Time | Ref. 5131G-010 | White Gold", "reference": "5131G-010", "price_usd": 88000.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "18k White Gold", "case_size_mm": 40.0, "movement": "Automatic", "complications": ["GMT / Dual Time", "World Time"], "merchant_slug": "a-collected-man", "merchant_name": "A Collected Man", "image_url": "https://cdn.shopify.com/s/files/1/0606/5325/products/Patek_Philippe_World_Time_Ref_5131G_010_White_Gold_A_Collected_Man_London_CDSWG_P1614_09.jpg?v=1663238355", "detail_url": "https://mostexpensivewatches.net/listing/h_6864494329939", "buy_url": "https://mostexpensivewatches.net/out/h_6864494329939", "available": false}], "auction_lots": [{"slug": "patek-philippe-5131g-001-2023", "brand": "Patek Philippe", "reference": "5131G-001", "model": "World Time Cloisonné Enamel", "case_material": "18k White Gold", "hammer_usd": 113000, "year_sold": 2023, "venue": "Bonhams London", "lot_summary": "Features a handcrafted cloisonné enamel dial depicting the continents of Europe, Africa, and the Americas, a technique reserved for Patek Philippe's most artistic timepieces.", "source_url": "https://www.bonhams.com/auctions/28011/lot/101/", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/patek-philippe-5131g-001-2023"}]}
