Omega 145.022 Speedmaster Professional Moonwatch SS Black Dial c. 1985

The Omega Speedmaster Professional Moonwatch reference 145.022 is a cornerstone of horological heritage, introduced in 1968 as the first Speedmaster to house the manually wound caliber 861—a robust and high-beat movement that replaced the legendary caliber 321 and elevated reliability and serviceability for collectors and professionals alike. Its 42 mm stainless steel case with twisted lyre lugs and 48 mm lug‑to‑lug span retains the classic Moonwatch proportions, while the 13 mm thickness ensures a presence on the wrist without sacrificing comfort. The black stepped dial, often featuring tritium luminous markers, paired with the iconic tachymeter bezel and hesalite crystal, speaks directly to its space‑flight legacy and utilitarian roots. Produced through the late 1960s into the 1980s, this reference became NASA‑qualified and even served on space shuttle missions—cementing its status as the “Moonwatch.” The manually wound caliber 861 movement, operating at 21,600 vph, offers a 48‑hour power reserve and a shuttle‑cam chronograph action prized for its crisp reset and reliability. While not a limited edition, the reference’s long production run and variations—such as step dials, logo types, and bezel fonts—make certain early examples highly sought after by seasoned collectors. Its enduring design, mechanical pedigree, and space‑flight provenance make the 145.022 a watch of profound significance and timeless appeal. Excellent condition with Omega box.
