This reference is the first Speedmaster to feature the black aluminum tachymeter bezel and \"Alpha\" style hands, replacing the Broad Arrow handset of the inaugural model. It utilizes the manual-wind Calibre 321 movement and a 39mm stainless steel case with straight lugs and no crown guards. Collectors prioritize the CK2998-1 for its transitional role in the model's evolution and its association with early space exploration, as a later CK2998 variant was the first Omega worn in space. On the secondary market, well-preserved examples typically command prices in the $150,000 to $250,000 range. A notable auction result occurred in 2018 when a CK2998-1 with a tropical dial sold for approximately $275,000, reflecting the premium placed on original components and uniform aging."}, "listing_stats": {"count": 349, "median": 5450.0, "low": 3000.0, "high": 74000.0, "brands": 1, "merchants": 7}, "listings": [{"id": "h_16484156408153", "title": "OMEGA Omega Speedmaster 145.022-69 Grey Racing dial with Original Box and Booklet", "brand": "OMEGA", "model": "Omega Speedmaster 145.022-69 Grey Racing dial with Original Box and Booklet", "reference": "145.022-69", "price_usd": 48500.0, "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-3895OmegaSpeedmaster145.022RacingdialwithoriginalboxesW-3895OmegaSpeedmaster145.022Racingdialwithoriginalboxes_118_1x1_9786c92d-c816-4b9e-8673-61b74ad2fbb8.jpg?v=1790686179", "detail_url": "https://mostexpensivewatches.net/listing/h_16484156408153", "buy_url": "https://mostexpensivewatches.net/out/h_16484156408153", "alt_buy_urls": [{"partner": "goldsmiths", "name": "Goldsmiths", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_16484156408153/via/goldsmiths"}, {"partner": "selfridges", "name": "Selfridges", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_16484156408153/via/selfridges"}, {"partner": "farfetch", "name": "Farfetch", "region": "Global", "url": "https://mostexpensivewatches.net/out/h_16484156408153/via/farfetch"}], "available": true}, {"id": "h_16351981928793", "title": "OMEGA Omega Speedmaster 2998 -61", "brand": "OMEGA", "model": "Omega Speedmaster 2998 -61", "reference": "2998", "price_usd": 23900.0, "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-3782OmegaSpeedmaster299861_392_1x1_51d6ecf6-72a1-4f58-86e0-621fdb42d188.jpg?v=1790686604", "detail_url": "https://mostexpensivewatches.net/listing/h_16351981928793", "buy_url": "https://mostexpensivewatches.net/out/h_16351981928793", "alt_buy_urls": [{"partner": "goldsmiths", "name": "Goldsmiths", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_16351981928793/via/goldsmiths"}, {"partner": "selfridges", "name": "Selfridges", "region": "UK", "url": "https://mostexpensivewatches.net/out/h_16351981928793/via/selfridges"}, {"partner": "farfetch", "name": "Farfetch", "region": "Global", "url": "https://mostexpensivewatches.net/out/h_16351981928793/via/farfetch"}], "available": true}, {"id": "h_15298845507967", "title": "OMEGA Stainless steel OMEGA Speedmaster ref. 105.002 chronograph wristwatch.
