Collectors target this reference for its manual-wind Caliber 567, a movement based on a Lemania ebauche that features a traditional strike governor and hand-finished components visible through a sapphire caseback. The dial is characterized by solid gold construction with hand-guilloché patterns, Roman numerals, and blued steel Breguet hands. The 36mm case includes the brand’s signature coin-edge fluting and straight lugs with screw-bars. On the secondary market, this reference typically trades in the $65,000 to $90,000 range depending on the presence of original documentation. A notable production detail is the inclusion of a \"jump hour\" variant, reference 3637BA, though the standard minute repeater remains the foundational complication for this specific lineage of neo-vintage Breguet timepieces."}, "listing_stats": {"count": 0, "median": 0, "low": 0, "high": 0}, "listings": [], "auction_lots": [{"slug": "breguet-3637-2020", "brand": "Breguet", "reference": "3637", "model": "Classique Minute Repeater", "case_material": "18k Rose Gold", "hammer_usd": 52500, "year_sold": 2020, "venue": "Christie's New York", "lot_summary": "A magnificent minute repeating wristwatch with a 24-hour indicator, showcasing four different styles of hand-crafted guilloché on the dial.", "source_url": "https://www.christies.com/en/lot/lot-6291412", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/breguet-3637-2020"}]}
