Speedmaster CK2998

The Omega Speedmaster CK2998 is a pivotal model in the Speedmaster lineage, first introduced in 1959 and famously worn by astronaut Wally Schirra during the Mercury-Atlas 8 mission. Its straight-lug case, symmetrical profile, and alpha hands set it apart from later Speedmasters, marking it as a favorite among collectors seeking the original pre-Moonwatch aesthetic. The 39.7mm case size offers a vintage-correct presence on the wrist, making it especially appealing to those who appreciate historically accurate proportions.

Key references include the original CK2998-1 through CK2998-6, each with subtle differences in dial details, hand shapes, and bezel inserts. Variations in the lollipop seconds hand and the use of the coveted "Base 1000" bezel can drive prices considerably higher. All original CK2998s house the manual-winding Caliber 321, a movement renowned for its column-wheel chronograph mechanism and direct lineage to later Moonwatch calibers, further enhancing desirability.

When assessing a CK2998, condition and originality are paramount—look for correct period parts, including the dial, hands, and bezel, as replacements or relumed components can impact value. Early references with untouched dials and original bezels command the strongest premiums, while later service parts or over-polished cases tend to reduce collector interest. This model’s scarcity, coupled with its historical significance, means competition for well-preserved examples is fierce, so be prepared to act decisively when the right piece appears.
