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": 453, "median": 6250.0, "low": 3000.0, "high": 74000.0, "brands": 1, "merchants": 7}, "listings": [{"id": "h_8029446734146", "title": "OMEGA Speedmaster Moonwatch Omega Co-Axial Master Chronometer Moonphase Chronograph -
