Collectors prioritize this reference for its oversized 39.5mm to 40mm stainless steel step-bezel case and the caliber 13ZN movement, which features a flyback chronograph complication. This specific model is distinguished by its central minute counter, utilizing two co-axial chronograph hands rather than a traditional sub-dial for minutes. Due to its technical complexity and limited production numbers, the 5699 is considered a high-tier vintage chronograph. On the secondary market, prices typically range from $60,000 to over $120,000 depending on condition and dial configuration. A notable variant includes the \"Sommer\" version, and a well-preserved example achieved a sale price of approximately 162,500 CHF at a 2017 Phillips auction, underscoring its value relative to standard 13ZN references."}, "listing_stats": {"count": 1, "median": 99000.0, "low": 99000.0, "high": 99000.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_15751432569177", "title": "Longines Longines 5699 Sommatore Steel Chronograph 13ZN Calibre", "brand": "Longines", "model": "Longines 5699 Sommatore Steel Chronograph 13ZN Calibre", "reference": "5699", "price_usd": 99000.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 39.5, "movement": "Automatic", "complications": ["Chronograph"], "merchant_slug": "bulang-and-sons", "merchant_name": "Bulang & Sons", "image_url": "https://cdn.shopify.com/s/files/1/0961/8613/8969/files/W-709_Longines_13ZN_Sommatore_Chronograph_02_2048x2048_d43b82ee-cbc6-4ec8-b458-9e412b7745d8.jpg?v=1756207310", "detail_url": "https://mostexpensivewatches.net/listing/h_15751432569177", "buy_url": "https://mostexpensivewatches.net/out/h_15751432569177", "available": false}], "auction_lots": [{"slug": "longines-5699-2025", "brand": "Longines", "reference": "5699", "model": "Doppia Lancetta", "case_material": "Stainless Steel", "hammer_usd": 106680, "year_sold": 2025, "venue": "Phillips New York", "lot_summary": "An exceptionally well-preserved example of the 'double hand' chronograph featuring the 13ZN-12 movement, gifted to a WWII veteran and noted oncologist.", "source_url": "https://www.phillips.com/detail/longines/NY080125/21", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/longines-5699-2025"}, {"slug": "longines-5699-2016", "brand": "Longines", "reference": "5699", "model": "Doppia Lancetta", "case_material": "Stainless Steel", "hammer_usd": 89250, "year_sold": 2016, "venue": "Phillips Geneva", "lot_summary": "A rare 1947 chronograph with two central hands for elapsed seconds and minutes, powered by the legendary caliber 13ZN.", "source_url": "https://www.phillips.com/detail/longines/CH080016/24", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/longines-5699-2016"}]}
