The Omega Speedmaster reference 145.022 represents a significant evolution within the Speedmaster lineage, transitioning from earlier references while retaining core design elements. This reference is characterized by its robust construction and the introduction of a new movement, distinguishing it from its predecessors. It served as a foundational model for subsequent Speedmaster iterations, establishing many of the visual and technical characteristics that would define the series for decades.

This reference features a stainless steel case with a diameter of 42 mm, housing the manual-winding caliber 861. The movement provides a power reserve of 48 hours. A Hesalite crystal protects the black dial, and the watch is rated for a water resistance of 50 meters. The fixed tachymeter bezel is a prominent feature, consistent with the functional design of the Speedmaster series.

For collectors, the 145.022 is notable for its long production run and the various dial and case back variations that emerged during its manufacturing period. It appeals to those interested in the technical progression of the Speedmaster, offering a blend of established design and updated mechanics. The reference is often found paired with a steel bracelet, reflecting its original configuration and utility.

The Omega Speedmaster Professional reference 145.022-69 represents a pivotal transition within the Speedmaster lineage, being one of the last references to utilize the revered Caliber 861 manual-winding movement before subsequent iterations. This reference is significant for its introduction of the applied Omega logo on the dial, moving away from the painted logo of earlier models, and for its diverse range of bezel and dial variations.

This reference typically features a 42mm stainless steel asymmetrical case with twisted lugs, a Hesalite crystal, and a black tachymeter bezel. Powering the watch is the Omega Caliber 861, a cam-actuated chronograph movement with 17 jewels, operating at 21,600 vibrations per hour and offering a power reserve of approximately 40 hours. The caseback often features the 'Flight-Qualified by NASA' engraving.

For collectors, the 145.022-69 is highly sought after due to its historical proximity to the 'Moonwatch' era, its robust and reliable movement, and the variety of subtle dial and bezel nuances that exist within the production run. These variations, such as different 'straight writing' or 'dot over 90' bezels, contribute to its collectibility and make it a rich area for specialized research among enthusiasts.
