This specific execution is distinguished by its three-register \"Noir Tachymeter\" configuration, featuring a matte black dial with a white outer tachymeter scale. Collectors prioritize this reference for its 36mm stainless steel case with sharp, faceted lugs and the manual-wind Valjoux 72 movement, a column-wheel caliber noted for its reliability and historical significance. The 2447NT is rarer than the standard silver-dial 2447S or black-dial 2447N due to the added functional scale. On the secondary market, prices typically range from $15,000 to $30,000 depending on the presence of original tritium lume and case sharpness. A notable production detail is the transition from \"Swiss\" only to \"T Swiss\" markings on the dial, which indicates the shift from radium to tritium luminous material during the mid-1960s."}, "listing_stats": {"count": 4, "median": 6375.0, "low": 4500.0, "high": 11000.0, "brands": 1, "merchants": 3}, "listings": [{"id": "h_6895312339019", "title": "Heuer Heuer Heuer Carrera 2447 N", "brand": "Heuer", "model": "Heuer Heuer Carrera 2447 N", "reference": "2447", "price_usd": 11000.0, "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/Heuer-Heuer-Carrera-2447-N-10-10-HEU-CVD80L-3957d4a5d476.jpg?v=1700671537", "detail_url": "https://mostexpensivewatches.net/listing/h_6895312339019", "buy_url": "https://mostexpensivewatches.net/out/h_6895312339019", "alt_buy_urls": [{"partner": "goldsmiths", "name": "Goldsmiths", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_6895312339019/via/goldsmiths"}, {"partner": "selfridges", "name": "Selfridges", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_6895312339019/via/selfridges"}, {"partner": "farfetch", "name": "Farfetch", "region": "Global", "url": "https://mostexpensivewatches.net/out/h_6895312339019/via/farfetch"}], "available": false}, {"id": "h_7189166129261", "title": "Heuer 1950s Heuer Pre-Carrera Chronograph (Ref. 3336) \"Decimeter\"", "brand": "Heuer", "model": "1950s Heuer Pre-Carrera Chronograph (Ref. 3336) \"Decimeter\"", "reference": "3336", "price_usd": 6850.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": ["Chronograph"], "merchant_slug": "craft-and-tailored", "merchant_name": "Craft + Tailored", "image_url": "https://cdn.shopify.com/s/files/1/1104/9180/files/Img024375.jpg?v=1706301510", "detail_url": "https://mostexpensivewatches.net/listing/h_7189166129261", "buy_url": "https://mostexpensivewatches.net/out/h_7189166129261", "alt_buy_urls": [{"partner": "goldsmiths", "name": "Goldsmiths", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_7189166129261/via/goldsmiths"}, {"partner": "selfridges", "name": "Selfridges", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_7189166129261/via/selfridges"}, {"partner": "farfetch", "name": "Farfetch", "region": "Global", "url": "https://mostexpensivewatches.net/out/h_7189166129261/via/farfetch"}], "available": false}, {"id": "h_15751385383257", "title": "Heuer Heuer Pre-Carrera Step Case Chronograph", "brand": "Heuer", "model": "Heuer Pre-Carrera Step Case Chronograph", "reference": "W-1288", "price_usd": 5900.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 37.0, "movement": "Automatic", "complications": ["Chronograph"], "merchant_slug": "bulang-and-sons", "merchant_name": "Bulang & Sons", "image_url": "https://cdn.shopify.com/s/files/1/0961/8613/8969/files/W-1288-Heuer-Pre-Carrera-Chronograph_001.jpg?v=1756206300", "detail_url": "https://mostexpensivewatches.net/listing/h_15751385383257", "buy_url": "https://mostexpensivewatches.net/out/h_15751385383257", "alt_buy_urls": [{"partner": "goldsmiths", "name": "Goldsmiths", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_15751385383257/via/goldsmiths"}, {"partner": "selfridges", "name": "Selfridges", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_15751385383257/via/selfridges"}, {"partner": "farfetch", "name": "Farfetch", "region": "Global", "url": "https://mostexpensivewatches.net/out/h_15751385383257/via/farfetch"}], "available": false}, {"id": "h_7594334060653", "title": "Heuer 2020 TAG Heuer Carrera Chronograph (Ref.
