This model represents the manufacturer’s first self-winding wristwatch, powered by the caliber 12-600 AT, which features a 30-jewel movement and an 18k gold rotor. Collectors prioritize this reference for its fired cream enamel dial and heavy two-body water-resistant case. While the majority of the estimated 580 total units were cased in yellow gold, the platinum execution is the rarest variant, with fewer than 25 examples documented publicly. Secondary market prices for platinum models typically reside in the mid-to-high six-figure range, significantly exceeding the values of gold counterparts. A notable auction result occurred in 2023 when a platinum 2526 with a Tiffany & Co. signed dial and a matching platinum bracelet sold for over 600,000 USD. Current market availability is limited to specialized vintage auctions and high-end secondary dealers."}, "listing_stats": {"count": 2, "median": 88500.0, "low": 82500.0, "high": 94500.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_7419537948759", "title": "Patek Philippe Patek Philippe Calatrava 2526 'Double Swiss'", "brand": "Patek Philippe", "model": "Patek Philippe Calatrava 2526 'Double Swiss'", "reference": "2526", "price_usd": 94500.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "analog-shift", "merchant_name": "Analog/Shift", "image_url": "https://cdn.shopify.com/s/files/1/0809/1255/files/AS10353_40930625_PATEKPHILIPPE_CALATRAVAYG_2526J-6.jpg?v=1749831053", "detail_url": "https://mostexpensivewatches.net/listing/h_7419537948759", "buy_url": "https://mostexpensivewatches.net/out/h_7419537948759", "available": false}, {"id": "h_7419594408023", "title": "Patek Philippe Patek Philippe Calatrava 2526 'First Series'", "brand": "Patek Philippe", "model": "Patek Philippe Calatrava 2526 'First Series'", "reference": "2526", "price_usd": 82500.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "analog-shift", "merchant_name": "Analog/Shift", "image_url": "https://cdn.shopify.com/s/files/1/0809/1255/files/AS10352_40930624_PATEKPHILIPPE_CALATRAVAYG_2526J-6.jpg?v=1749826891", "detail_url": "https://mostexpensivewatches.net/listing/h_7419594408023", "buy_url": "https://mostexpensivewatches.net/out/h_7419594408023", "available": false}], "auction_lots": [{"slug": "patek-philippe-2526-platinum-enamel", "brand": "Patek Philippe", "reference": "2526", "model": "First Automatic Enamel", "case_material": "Platinum", "hammer_usd": 500000, "year_sold": 2022, "venue": "Phillips Geneva", "lot_summary": "The reference 2526 was Patek's first automatic watch, and this platinum example features a pristine white grand feu enamel dial.
