Collectors prioritize this reference for its caliber RD5707, which carries the Geneva Seal and is based on a Longines L990 base with a complication module by Agenhor. The 37mm case features the original Sympathie design with complex faceted lugs and a shaped sapphire crystal that follows the unconventional geometry of the bezel. The dial displays a bi-retrograde layout for the day and date, alongside a moon phase and leap year indicator. Production was limited, often to 28 pieces per metal variant. On the secondary market, these watches typically trade between $40,000 and $65,000. A notable auction result occurred at Phillips in 2022, where a white gold example reached approximately $60,000."}, "listing_stats": {"count": 1, "median": 44000.0, "low": 44000.0, "high": 44000.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_6740074070099", "title": "Roger Dubuis Sympathie Chronograph S37 | Rose Gold", "brand": "Roger Dubuis", "model": "Sympathie Chronograph S37 | Rose Gold", "reference": "WRG_R1440", "price_usd": 44000.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "18k Rose Gold", "case_size_mm": 40.0, "movement": "Automatic", "complications": ["Chronograph"], "merchant_slug": "a-collected-man", "merchant_name": "A Collected Man", "image_url": "https://cdn.shopify.com/s/files/1/0606/5325/products/Roger_Dubuis_Sympathie_ChronographA_Collected_Man_London_WRG_R1440_09.jpg?v=1648641354", "detail_url": "https://mostexpensivewatches.net/listing/h_6740074070099", "buy_url": "https://mostexpensivewatches.net/out/h_6740074070099", "available": false}], "auction_lots": [{"slug": "roger-dubuis-s37-57070-2022", "brand": "Roger Dubuis", "reference": "S37 57070", "model": "Sympathie Bi-retrograde Perpetual Calendar", "case_material": "18k White Gold", "hammer_usd": 50400, "year_sold": 2022, "venue": "Sotheby's New York", "lot_summary": "A limited edition (4/28) white gold perpetual calendar with moon phases, epitomizing the complex early work of Roger Dubuis.", "source_url": "https://www.sothebys.com/en/buy/auction/2022/fine-watches-2/reference-s37-57070-sympathie-a-limited-edition", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/roger-dubuis-s37-57070-2022"}, {"slug": "roger-dubuis-s37-56-5-2025", "brand": "Roger Dubuis", "reference": "S37 56 5", "model": "Sympathie S37", "case_material": "18k Pink Gold", "hammer_usd": 25400, "year_sold": 2025, "venue": "Phillips New York", "lot_summary": "An early Sympathie chronograph with a black luminous dial, showcasing the brand's unique case design and high-level movement finishing.", "source_url": "https://www.phillips.com/detail/roger-dubuis/NY080325/16", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/roger-dubuis-s37-56-5-2025"}, {"slug": "roger-dubuis-s37-57-5-2022", "brand": "Roger Dubuis", "reference": "S37.57.5", "model": "Sympathie", "case_material": "18k Pink Gold", "hammer_usd": 19050, "year_sold": 2022, "venue": "Phillips New York", "lot_summary": "A fine pink gold wristwatch with a cream dial and Breguet numerals, featuring the automatic caliber 57 with the Geneva Seal.", "source_url": "https://www.phillips.com/detail/roger-dubuis/NY080322/105", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/roger-dubuis-s37-57-5-2022"}, {"slug": "roger-dubuis-s37-570-2024", "brand": "Roger Dubuis", "reference": "S37 570", "model": "Sympathie", "case_material": "18k White Gold", "hammer_usd": 12160, "year_sold": 2024, "venue": "Bonhams New York", "lot_summary": "A limited edition automatic wristwatch from the early 2000s, featuring the brand's signature Sympathie case design and a black dial.", "source_url": "https://www.bonhams.com/auctions/30693/lot/49/", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/roger-dubuis-s37-570-2024"}]}
