Omega 145.022 Speedmaster Professional Stainless Steel Black Dial Circa 1969

The Omega 145.022 Speedmaster Professional is a storied chronograph introduced in 1968 as the successor to the Caliber 321 models, featuring the rugged and reliable Caliber 861 manual‑winding movement. Its 42 mm asymmetrical stainless steel case with lyre lugs, paired with a black tachymeter bezel and hesalite crystal, preserves the iconic Moonwatch aesthetic while offering improved durability and serviceability. The 48 mm lug‑to‑lug span and 14 mm thickness give it a commanding yet wearable presence on the wrist. The Caliber 861, running at 21,600 vph with approximately 48 hours of power reserve, marked a technical leap forward with its shuttle‑cam chronograph mechanism and robust construction. Produced through the late 1960s into the 1980s, the 145.022 remains highly sought after by collectors for its direct lineage to NASA’s space missions and its enduring design. The black dial with tri‑register layout, luminous baton indices, and chronograph registers offers superb legibility and vintage charm. This reference stands as a cornerstone of chronograph history, blending horological significance, space‑flight heritage, and mechanical excellence. Excellent Condition with European Watch Company leather pouch.
