Based on the Reference 1463 \"Tasti Tondi\" water-resistant case, it features a screw-down caseback and round fluted pushers. The watch is powered by the manual-wind Caliber 13-130, modified with a split-seconds mechanism. Collectors value this reference for its extreme rarity and its status as one of the few vintage waterproof split-seconds chronographs ever manufactured by the brand. One notable example belonged to jazz musician Duke Ellington, featuring a silvered dial with Breguet numerals. Due to its scarcity, the Reference 1563 rarely appears at auction. When it does, market values typically reach the mid-to-high seven-figure range. A yellow gold example sold at Christie’s in 2013 for approximately 1.45 million CHF, while current valuations for the few existing pieces exceed several million dollars."}, "listing_stats": {"count": 2, "median": 243885.0, "low": 209770.0, "high": 278000.0, "brands": 1, "merchants": 2}, "listings": [{"id": "h_6957465894995", "title": "Patek Philippe Split Seconds Chronograph | 5004 | White Gold", "brand": "Patek Philippe", "model": "Split Seconds Chronograph | 5004 | White Gold", "reference": "5004", "price_usd": 278000.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "18k White Gold", "case_size_mm": 40.0, "movement": "Automatic", "complications": ["Perpetual Calendar", "Chronograph", "Split-Seconds Chronograph"], "merchant_slug": "a-collected-man", "merchant_name": "A Collected Man", "image_url": "https://cdn.shopify.com/s/files/1/0606/5325/products/Patek_Philippe_Split_Seconds_Chronograph_5004_whitegold_A_Collected_Man_London_00.jpg?v=1678889909", "detail_url": "https://mostexpensivewatches.net/listing/h_6957465894995", "buy_url": "https://mostexpensivewatches.net/out/h_6957465894995", "available": false}, {"id": "h_7317322399831", "title": "Patek Philippe Patek Philippe Split-Seconds Chronograph", "brand": "Patek Philippe", "model": "Patek Philippe Split-Seconds Chronograph", "reference": "40930538", "price_usd": 209770.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": ["Chronograph", "Split-Seconds Chronograph"], "merchant_slug": "analog-shift", "merchant_name": "Analog/Shift", "image_url": "https://cdn.shopify.com/s/files/1/0809/1255/files/AS10164_40930538_PATEKPHILIPPE_SPLITSECONDSCHRONOGRAPH_5370P-011-5.jpg?v=1730518237", "detail_url": "https://mostexpensivewatches.net/listing/h_7317322399831", "buy_url": "https://mostexpensivewatches.net/out/h_7317322399831", "available": false}], "auction_lots": [{"slug": "patek-philippe-1563-2024", "brand": "Patek Philippe", "reference": "1563", "model": "Split-Seconds Chronograph", "case_material": "18k Yellow Gold", "hammer_usd": 3820000, "year_sold": 2024, "venue": "Sotheby's Geneva", "lot_summary": "One of only three known examples of Ref. 1563, this unique piece is distinguished by its luminous Breguet numerals and hands.", "source_url": "https://www.sothebys.com/en/buy/auction/2024/treasures-of-time/reference-1563-a-unique-yellow-gold-split-second", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/patek-philippe-1563-2024"}]}
