Collectors prioritize this reference for its black PVD-coated stainless steel case, a departure from the standard brushed steel finishes of the era. It is powered by the manual-wind Valjoux 7740 movement rather than the earlier automatic Calibre 11 or 12. The dial features a matte black finish with orange accents on the hands and registers, creating a high-contrast aesthetic. Due to the fragility of early PVD coatings, finding examples with intact finishes is difficult, contributing to its rarity. On the secondary market, prices typically range from $40,000 to $80,000 depending on the condition of the coating. A notable example, formerly owned by Sammy Davis Jr., sold at auction in 2021 for over $450,000, highlighting the premium placed on provenance."}, "listing_stats": {"count": 1, "median": 8900.0, "low": 8900.0, "high": 8900.0, "brands": 1, "merchants": 1}, "listings": [{"id": "h_15751426900313", "title": "Heuer Heuer Monaco Ref 1133 Grey Dial", "brand": "Heuer", "model": "Heuer Monaco Ref 1133 Grey Dial", "reference": "1133", "price_usd": 8900.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "bulang-and-sons", "merchant_name": "Bulang & Sons", "image_url": "https://cdn.shopify.com/s/files/1/0961/8613/8969/files/W-782_Heuer_Monaco_1133_09-2.jpg?v=1756207204", "detail_url": "https://mostexpensivewatches.net/listing/h_15751426900313", "buy_url": "https://mostexpensivewatches.net/out/h_15751426900313", "alt_buy_urls": [{"partner": "goldsmiths", "name": "Goldsmiths", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_15751426900313/via/goldsmiths"}, {"partner": "selfridges", "name": "Selfridges", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_15751426900313/via/selfridges"}, {"partner": "farfetch", "name": "Farfetch", "region": "Global", "url": "https://mostexpensivewatches.net/out/h_15751426900313/via/farfetch"}], "available": false}], "auction_lots": [{"slug": "heuer-740303-n-2010", "brand": "Heuer", "reference": "740303 N", "model": "Monaco PVD \"Dark Lord\"", "case_material": "Black PVD Coated Stainless Steel", "hammer_usd": 74700, "year_sold": 2010, "venue": "Bonhams London", "lot_summary": "A near-mint example from the Arno Haslinger collection, this rare black PVD Monaco achieved a record price at the time, doubling its high estimate.", "source_url": "https://www.bonhams.com/auctions/18267/lot/98/", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/heuer-740303-n-2010"}]}
