Collectors value this reference for its Calibre 563, an automatic movement based on a Lemania ebauche featuring a unique instant-jump time zone complication. The 38mm case features the brand’s signature coin-edge fluting and a solid gold dial decorated with hand-guilloché wave patterns. Unlike modern world timers, the 3700 utilizes a simplified city disc system adjusted via the crown at 3 o'clock. On the secondary market, this reference typically trades between $12,000 and $18,000 depending on the presence of the original gold bracelet or leather strap. A notable production detail is the \"hidden\" signature on the dial, a security feature Breguet utilized to distinguish authentic pieces from contemporary counterfeits."}, "listing_stats": {"count": 1, "median": 12500.0, "low": 12500.0, "high": 12500.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_6930721407051", "title": "Breguet Breguet Hora Mundi 3700BB", "brand": "Breguet", "model": "Breguet Hora Mundi 3700BB", "reference": "3700BB", "price_usd": 12500.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "hodinkee", "merchant_name": "Hodinkee Shop", "image_url": "https://cdn.shopify.com/s/files/1/0146/0732/products/Breguet-Hora-Mundi-3700BB-10-10-BRG-G9VA4Y-26e5a7783223.jpg?v=1709586177", "detail_url": "https://mostexpensivewatches.net/listing/h_6930721407051", "buy_url": "https://mostexpensivewatches.net/out/h_6930721407051", "available": false}], "auction_lots": [{"slug": "breguet-3700-2017", "brand": "Breguet", "reference": "3700", "model": "Marine Hora Mundi", "case_material": "18k Yellow Gold", "hammer_usd": 10625, "year_sold": 2017, "venue": "Christie's New York", "lot_summary": "An iconic world time wristwatch from the Marine collection, featuring 24 cities on the dial and a distinctive wave-pattern guilloché.", "source_url": "https://www.christies.com/en/lot/lot-6104333", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/breguet-3700-2017"}]}
