Omega 145.012 Vintage Speedmaster Professional Pre-Moon SS Black Dial

The Omega Speedmaster Professional reference 145.012 stands as one of the most important vintage Speedmasters ever produced, representing the final reference to house the legendary manual-wind Caliber 321. Produced in the late 1960s, with examples most commonly associated with 1967 to 1969, it marks the end of the original column-wheel chronograph era before Omega transitioned to the Caliber 861. Its 42mm asymmetric stainless steel lyre-lug case established the familiar Professional profile that would define the Moonwatch for decades to come. The matte black dial, typically with an applied Omega logo on earlier examples, gives the watch the purposeful, highly legible character collectors expect from a true pre-Moon Speedmaster. Inside, the Lemania-based Caliber 321 remains the principal attraction, prized for its architecture, historical relevance, and direct connection to the most revered chapter of Speedmaster collecting. The reference is especially appreciated for combining the robust Professional case with one of Omega's most respected chronograph movements, making it a cornerstone piece for serious vintage enthusiasts. Offered on a strap, the watch takes on a more understated and period-correct character, emphasizing the pure instrument quality of the design. It is not a limited edition, nor was it made for a specific boutique or country, which only reinforces its significance as a core production reference with outsized historical importance. Among vintage chronographs, the 145.012 remains one of the most compelling entries into top-tier Speedmaster collecting because it delivers genuine Caliber 321 pedigree in a reference widely recognized by the enthusiast community. Excellent Condition with EWC leather travel pouch.
