Collectors prioritize this reference for its 39.7mm straight-lug case, \"Alpha\" style hands, and the manual-wind Calibre 321 movement. This specific sub-reference is distinguished by its \"Base 1000\" or \"Tachymètre\" bezel and the introduction of the \"drop-straight\" chronograph seconds hand, which replaced the earlier lollipop style. As a pre-Professional model without crown guards, it occupies a specific niche in the evolution toward the moon-watch configuration. On the secondary market, prices typically range from $25,000 to $50,000 depending on the integrity of the \"Dot Over Ninety\" bezel and dial patina. A notable production detail is that the CK2998 series was the first Omega worn in space by astronaut Wally Schirra during the Mercury-Atlas 8 mission.", "score": 187}, {"slug": "omega-ck2998-1", "brand": "Omega", "ref": "CK2998-1", "model": "Speedmaster", "case_material": "Stainless Steel", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/omega-ck2998-1", "description": "The Omega Speedmaster CK2998-1 was produced between 1959 and 1960 as the successor to the CK2915. 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.", "score": 20}, {"slug": "omega-ck2998-62", "brand": "Omega", "ref": "CK2998-62", "model": "Speedmaster", "case_material": "Stainless Steel", "provenance": "extracted_from_auction_comps", "url": "https://mostexpensivewatches.net/reference/omega-ck2998-62", "description": "The Omega Speedmaster CK2998-62 was produced for approximately one year, beginning in 1962, and represents the final iteration of the CK2998 reference series. Collectors prioritize this model as a transitional piece featuring the manual-wind Calibre 321 movement and the 39mm straight-lug case design without crown guards. This specific sub-reference is distinguished by its \"Alpha\" hands and the introduction of the \"Dauphine\" style chronograph seconds hand, alongside a \"Base 1000\" or \"Base 500\" tachymeter bezel. Due to its limited production window and historical position as the precursor to the 105.002, market values typically range from $25,000 to over $50,000 depending on the presence of the original \"Dot Over 90\" bezel and dial patination. A notable production detail is that late-series CK2998-62 examples occasionally feature baton hands, marking the aesthetic shift toward the later professional models.", "score": 20}]}
