Collectors value this reference for its 33mm platinum case and the caliber 2120/2800, a self-winding movement based on the Jaeger-LeCoultre 920 base with a perpetual calendar module. The open-worked dial features four sub-dials for day, date, month, and moon phase, often accented by blued steel hands and white sub-dial rings for legibility. Its rarity is defined by limited production numbers compared to standard solid-dial variants. On the secondary market, this reference typically trades in the $60,000 to $90,000 range depending on the presence of the original box and papers. A notable production detail is the use of a sapphire caseback, which was a transition from the solid casebacks found on earlier 25656 or 25668 references."}, "listing_stats": {"count": 2, "median": 25000.0, "low": 22000.0, "high": 28000.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_6804884258899", "title": "Audemars Piguet Quantième Perpétuel Automatique | 5548BA | Yellow Gold", "brand": "Audemars Piguet", "model": "Quantième Perpétuel Automatique | 5548BA | Yellow Gold", "reference": "5548BA", "price_usd": 28000.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "18k Yellow Gold", "case_size_mm": 40.0, "movement": "Automatic", "complications": ["Perpetual Calendar"], "merchant_slug": "a-collected-man", "merchant_name": "A Collected Man", "image_url": "https://cdn.shopify.com/s/files/1/0606/5325/products/Audemars_Piguet_Quantieme_Perpetuel_Automatique_5548BA_Yellow_Gold_A_Collected_Man_London_CJCYG_A1573_10.jpg?v=1657536308", "detail_url": "https://mostexpensivewatches.net/listing/h_6804884258899", "buy_url": "https://mostexpensivewatches.net/out/h_6804884258899", "available": false}, {"id": "h_6861524435027", "title": "Audemars Piguet Quantième Perpétuel Automatique | 25657OR | Rose Gold", "brand": "Audemars Piguet", "model": "Quantième Perpétuel Automatique | 25657OR | Rose Gold", "reference": "25657OR", "price_usd": 22000.0, "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", "Moon Phase"], "merchant_slug": "a-collected-man", "merchant_name": "A Collected Man", "image_url": "https://cdn.shopify.com/s/files/1/0606/5325/products/Audemars_Piguet_Quantieme_Perpetuel_Automatique_25657OR_Rose_Gold_A_Collected_Man_London_CBLRG_A1595_09.jpg?v=1663059484", "detail_url": "https://mostexpensivewatches.net/listing/h_6861524435027", "buy_url": "https://mostexpensivewatches.net/out/h_6861524435027", "available": false}], "auction_lots": [{"slug": "audemars-piguet-25736pt-2025", "brand": "Audemars Piguet", "reference": "25736PT", "model": "Quantième Perpétuel Automatique", "case_material": "Platinum", "hammer_usd": 165600, "year_sold": 2025, "venue": "Bonhams New York", "lot_summary": "A fine platinum automatic perpetual calendar featuring a rare mother-of-pearl dial and the iconic ultra-thin Caliber 2120/2800.", "source_url": "https://www.bonhams.com/press_release/38473/", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/audemars-piguet-25736pt-2025"}]}
