This 36mm 18k yellow gold timepiece is valued for its regulator-style display, which separates the hours into a subdial at 12 o’clock while the central hand tracks minutes, mimicking historical precision clocks. It features a solid gold, hand-guilloché dial and the automatic Caliber 591, a movement based on a Lemania 8810 ebauche. The case incorporates signature brand elements including a coin-edged midcase and soldered straight lugs. On the secondary market, this reference typically trades between $12,000 and $18,000 depending on condition and the presence of original documentation. While the yellow gold 1747BA is the most common iteration, a limited series of 300 pieces was produced in platinum (1747PT) for the 1997 anniversary."}, "listing_stats": {"count": 1, "median": 11900.0, "low": 11900.0, "high": 11900.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_15751342883161", "title": "Breguet Breguet Regulator 1747 Limited Edition 18K Gold Automatic", "brand": "Breguet", "model": "Breguet Regulator 1747 Limited Edition 18K Gold Automatic", "reference": "1747", "price_usd": 11900.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "18k Yellow Gold", "case_size_mm": 36.0, "movement": "Automatic", "complications": [], "merchant_slug": "bulang-and-sons", "merchant_name": "Bulang & Sons", "image_url": "https://cdn.shopify.com/s/files/1/0961/8613/8969/files/W-1848BreguetRegulatorLimitedEditioninYellowGold_020_1x1_70596f92-75db-4112-a3e7-e352860e9d28.jpg?v=1756205396", "detail_url": "https://mostexpensivewatches.net/listing/h_15751342883161", "buy_url": "https://mostexpensivewatches.net/out/h_15751342883161", "available": false}], "auction_lots": [{"slug": "breguet-1747ba-11-286-2021", "brand": "Breguet", "reference": "1747BA/11/286", "model": "Classique Regulator 1747", "case_material": "18k Yellow Gold", "hammer_usd": 19626, "year_sold": 2021, "venue": "Phillips Hong Kong", "lot_summary": "A regulator-dial wristwatch produced in 1997 to celebrate the 250th anniversary of the birth of Abraham-Louis Breguet.", "source_url": "https://www.phillips.com/detail/breguet/HK080221/976", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/breguet-1747ba-11-286-2021"}]}
