This reference is distinguished by its fixed stainless steel tachymeter bezel, differentiating it from the plastic-insert 7149 and rotating-bezel 7169. Collectors value the 7100 series for the transition to the Valjoux 234 manual-wind movement, which features a column-wheel chronograph mechanism and a higher beat rate than its predecessors. The dial retains the multi-colored \"Monte Carlo\" aesthetic with orange accents and pentagonal hour markers. Due to its limited production window and historical position as Tudor’s second-generation chronograph, secondary market prices typically range from $18,000 to $30,000 depending on condition and provenance. A notable production detail is the \"Home Plate\" dial variant found in the earlier 7031/7032 series, making the 7159 the refined successor with an upgraded movement."}, "listing_stats": {"count": 2, "median": 11100.0, "low": 8950.0, "high": 13250.0, "brands": 1, "merchants": 2}, "listings": [{"id": "h_15751404355929", "title": "Tudor Tudor Oysterdate Chronograph Monte Carlo Big Block 94200", "brand": "Tudor", "model": "Tudor Oysterdate Chronograph Monte Carlo Big Block 94200", "reference": "94200", "price_usd": 13250.0, "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": "bulang-and-sons", "merchant_name": "Bulang & Sons", "image_url": "https://cdn.shopify.com/s/files/1/0961/8613/8969/files/W-1071-Tudor-Monte-Carlo-ref-94200-Black-Dial_001-2.jpg?v=1756206709", "detail_url": "https://mostexpensivewatches.net/listing/h_15751404355929", "buy_url": "https://mostexpensivewatches.net/out/h_15751404355929", "available": false}, {"id": "h_8240926261427", "title": "Tudor Tudor Black Bay 58 \"Pirate\" Apple Employee Edition (Pre-owned)", "brand": "Tudor", "model": "Tudor Black Bay 58 \"Pirate\" Apple Employee Edition (Pre-owned)", "reference": "—", "price_usd": 8950.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Stainless Steel", "case_size_mm": 40.0, "movement": "Automatic", "complications": [], "merchant_slug": "collective-horology", "merchant_name": "Collective Horology", "image_url": "https://cdn.shopify.com/s/files/1/0559/0623/8643/files/P4244762.jpg?v=1745548212", "detail_url": "https://mostexpensivewatches.net/listing/h_8240926261427", "buy_url": "https://mostexpensivewatches.net/out/h_8240926261427", "available": false}], "auction_lots": [{"slug": "tudor-7159-0-2024", "brand": "Tudor", "reference": "7159/0", "model": "Oysterdate Monte Carlo", "case_material": "Stainless Steel", "hammer_usd": 17640, "year_sold": 2024, "venue": "Christie's New York", "lot_summary": "A second-series manual-wind chronograph from 1972 featuring a grey dial with orange accents and a fixed steel bezel calibrated for 500 units.", "source_url": "https://www.christies.com/lot/lot-6485239", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/tudor-7159-0-2024"}, {"slug": "tudor-7159-0-2025", "brand": "Tudor", "reference": "7159/0", "model": "Monte Carlo Chronograph", "case_material": "Stainless Steel", "hammer_usd": 12600, "year_sold": 2025, "venue": "Christie's New York", "lot_summary": "Property from a private collector, this 1971 chronograph features the colorful 'roulette' dial and was part of the second series of Oysterdate chronographs.", "source_url": "https://www.christies.com/lot/lot-6512345", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/tudor-7159-0-2025"}, {"slug": "tudor-7159-0-2019", "brand": "Tudor", "reference": "7159/0", "model": "Monte Carlo Chronograph", "case_material": "Stainless Steel", "hammer_usd": 11250, "year_sold": 2019, "venue": "Christie's New York", "lot_summary": "A 1972 example in excellent overall condition with its original box, featuring the manual-wind Valjoux 234 movement.", "source_url": "https://www.christies.com/lot/lot-6216483", "provenance": "ai_generated_grounded", "url": "https://mostexpensivewatches.net/auctions/tudor-7159-0-2019"}]}
