The Omega Speedmaster CK2998-2 is an early iteration of the Speedmaster line, produced shortly after the original CK2915. It represents a transitional period, retaining many of the design cues that define the pre-Professional Speedmasters while introducing subtle refinements. This reference is part of the broader CK2998 series, which saw several sub-references with minor variations in hands and bezels, establishing the Speedmaster's identity as a robust chronograph.

This reference typically features a stainless steel case with straight lugs, a black dial, and a tachymeter bezel. Powering the watch is the manual-winding Omega Caliber 321, a column-wheel chronograph movement. The dial often presents with alpha hands for the hour and minute, a departure from the broad arrow hands of its predecessor, and often exhibits a desirable aged patina on its luminous elements.

For collectors, the CK2998-2 is highly sought after due to its historical significance as an early Speedmaster and its distinctive aesthetic. Its position in the lineage, bridging the gap between the very first Speedmasters and the later 'Professional' models, makes it a key reference for understanding the evolution of this celebrated chronograph. Examples with original components and an attractive patina are particularly valued.
