While the 3357 remains in the current catalog, its production spans several decades of the brand’s post-quartz crisis history. Collectors value this reference for the manual-wind Calibre 558.1, which features a 2.5Hz frequency and extensive hand-engraving visible through the sapphire caseback. The 35mm case houses a solid gold dial decorated with three distinct guilloché patterns and an aperture at six o’clock displaying the tourbillon carriage. On the secondary market, this white gold reference typically trades between $35,000 and $50,000 depending on the presence of original documentation. A notable production detail is the shift from \"Breguet\" to \"Breguet Nouvelle\" markings on movements during the transition of ownership to the Swatch Group in 1999."}, "listing_stats": {"count": 4, "median": 44250.0, "low": 33000.0, "high": 120000.0, "brands": 1, "merchants": 3}, "listings": [{"id": "h_7670123626583", "title": "Breguet Breguet Classique Tourbillon Extra-Plat", "brand": "Breguet", "model": "Breguet Classique Tourbillon Extra-Plat", "reference": "40993342", "price_usd": 120000.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": ["Tourbillon"], "merchant_slug": "analog-shift", "merchant_name": "Analog/Shift", "image_url": "https://cdn.shopify.com/s/files/1/0809/1255/files/AS12425_40993342_BREGUET_CLASSIQUETOURBILLONEXTRA-PLAT_5377PT-12-9WU--1_33d94409-626a-4ea5-b9e2-d50e6168981d.jpg?v=1781627068", "detail_url": "https://mostexpensivewatches.net/listing/h_7670123626583", "buy_url": "https://mostexpensivewatches.net/out/h_7670123626583", "available": false}, {"id": "h_7015067123821", "title": "Breguet 2010s Breguet Classique Complications Tourbillon (Ref. 3358) 18K WG W/ Factory Diamond Case & MOP Guilloche Dial", "brand": "Breguet", "model": "2010s Breguet Classique Complications Tourbillon (Ref. 3358) 18K WG W/ Factory Diamond Case & MOP Guilloche Dial", "reference": "3358", "price_usd": 52000.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": ["Tourbillon"], "merchant_slug": "craft-and-tailored", "merchant_name": "Craft + Tailored", "image_url": "https://cdn.shopify.com/s/files/1/1104/9180/files/Img018563.jpg?v=1705444066", "detail_url": "https://mostexpensivewatches.net/listing/h_7015067123821", "buy_url": "https://mostexpensivewatches.net/out/h_7015067123821", "available": false}, {"id": "h_6756030283859", "title": "Breguet Tourbillon | Ref. 3357 | Yellow Gold", "brand": "Breguet", "model": "Tourbillon | Ref. 3357 | Yellow Gold", "reference": "3357", "price_usd": 36500.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "18k Yellow Gold", "case_size_mm": 40.0, "movement": "Automatic", "complications": ["Tourbillon"], "merchant_slug": "a-collected-man", "merchant_name": "A Collected Man", "image_url": "https://cdn.shopify.com/s/files/1/0606/5325/products/Breguet_Tourbillon_Ref_3357_YellowGA_Collected_Man_London_WYG_B1525_10.jpg?v=1651166257", "detail_url": "https://mostexpensivewatches.net/listing/h_6756030283859", "buy_url": "https://mostexpensivewatches.net/out/h_6756030283859", "available": false}, {"id": "h_6730849124435", "title": "Breguet Tourbillon | 3357 | White Gold", "brand": "Breguet", "model": "Tourbillon | 3357 | White Gold", "reference": "3357", "price_usd": 33000.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "18k White Gold", "case_size_mm": 40.0, "movement": "Automatic", "complications": ["Tourbillon"], "merchant_slug": "a-collected-man", "merchant_name": "A Collected Man", "image_url": "https://cdn.shopify.com/s/files/1/0606/5325/products/03_10_22_Breguet_Tourbillon_65copy.jpg?v=1647353037", "detail_url": "https://mostexpensivewatches.net/listing/h_6730849124435", "buy_url": "https://mostexpensivewatches.net/out/h_6730849124435", "available": false}], "auction_lots": [{"slug": "breguet-3357-2021", "brand": "Breguet", "reference": "3357", "model": "Classique Tourbillon", "case_material": "18k White Gold", "hammer_usd": 35000, "year_sold": 2021, "venue": "Christie's New York", "lot_summary": "A diamond-set version of the iconic Tourbillon Messidor, featuring a hand-engraved movement visible through the sapphire caseback.", "source_url": "https://www.christies.com/en/lot/lot-6321230", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/breguet-3357-2021"}]}
