Collectors prioritize this reference because it was the first Speedmaster to feature an asymmetrical case with integrated crown guards and twisted \"lyre\" lugs, establishing the modern Professional silhouette. It is historically significant as the specific model worn by Apollo 11 astronauts during the first lunar EVA. The watch utilizes the manual-wind Calibre 321 lateral clutch chronograph movement. Key details include a \"dot over ninety\" (DON) bezel and a stepped dial with an applied metal logo. On the secondary market, prices typically range from $12,000 to over $30,000 depending on the specific sub-reference and component originality. A notable production variant is the 105.012-63, which features a double-step caseback and is considered the earliest iteration of the reference, often commanding a premium at auction due to its limited production window."}, "listing_stats": {"count": 211, "median": 5300.0, "low": 3000.0, "high": 52270.0, "brands": 1, "merchants": 6}, "listings": [{"id": "h_8029451813186", "title": "OMEGA Speedmaster Moonwatch Professional Chronograph Calibre 321 - 42 mm Platinum Case - Black Dial - Black Leather Strap - 311.93.42.30.99.001", "brand": "OMEGA", "model": "Speedmaster Moonwatch Professional Chronograph Calibre 321 - 42 mm Platinum Case - Black Dial - Black Leather Strap - 311.93.42.30.99.001", "reference": "311.93", "price_usd": 52270.0, "currency": "USD", "condition": "excellent", "box_papers": "full_set", "year": null, "case_material": "Platinum", "case_size_mm": 42.0, "movement": "Automatic", "complications": ["Chronograph"], "merchant_slug": "watch-affinity", "merchant_name": "Watch-Affinity", "image_url": "https://cdn.shopify.com/s/files/1/0683/2449/1586/products/31193423099001.jpg?v=1669756256", "detail_url": "https://mostexpensivewatches.net/listing/h_8029451813186", "buy_url": "https://mostexpensivewatches.net/out/h_8029451813186", "available": true}, {"id": "h_16280589893977", "title": "OMEGA Omega Speedmaster 105.003 Ed White Tropical Brown Dial Pulsations Bezel with Extract of the Archives", "brand": "OMEGA", "model": "Omega Speedmaster 105.003 Ed White Tropical Brown Dial Pulsations Bezel with Extract of the Archives", "reference": "105.003", "price_usd": 24900.0, "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-3754OmegaSpeedmasterST105.003TropicalDialPulsationsBezelwithExtractoftheArchives_018_1x1_d87c9bec-beaf-4647-88bc-f75dfd162b9d.jpg?v=1777627229", "detail_url": "https://mostexpensivewatches.net/listing/h_16280589893977", "buy_url": "https://mostexpensivewatches.net/out/h_16280589893977", "available": true}, {"id": "h_15298845507967", "title": "OMEGA Stainless steel OMEGA Speedmaster ref. 105.002 chronograph wristwatch.
