Omega Speedmaster Professional

About this reference

The Omega Speedmaster Professional reference 145.012 was produced between approximately 1967 and 1969. Collectors prioritize this reference because it is the final Speedmaster to house the column-wheel Calibre 321 movement before the transition to the cam-actuated Calibre 861. It features the asymmetrical 42mm stainless steel case with twisted lyre lugs and integrated crown guards. This reference is historically significant as the specific model worn by the majority of Apollo astronauts on the lunar surface. On the secondary market, prices typically range from $10,000 to $20,000 depending on the condition of the "Dot Over 90" bezel and dial patina. A notable production variant is the 145.012-67 SP, which often features a specific pusher design. While more common than the symmetrical-case 105.003, the 145.012 remains a primary target for those seeking the original technical specifications used during the NASA moon landings.
