Reasons to Bid

This Speedmaster Ref. 145.022-76 ST represents the late-1970s continuation of the Moonwatch line, retaining the classic case shape, dial layout, and hand design associated with NASA-era Speedmasters. The watch is powered by the Caliber 861, a reliable movement used by Omega for decades before being replaced by the Caliber 1861. As a well-preserved example of a reference produced for only a limited period, it offers an accessible entry into collecting vintage Speedmasters while maintaining the historical continuity of the model.
