Early iterations are distinguished by their countdown bezels and thin \"thin-arrow\" seconds hands. Due to the fragile nature of the original acrylic bezel inserts, examples with intact, original components are rare. On the secondary market, prices typically range from $15,000 to over $50,000 depending on the specific sub-reference and condition.

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.

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.

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.
