Omega Speedmaster Professional Moonwatch 145.022-69 ST

Omega Speedmaster Professional Moonwatch SS Black Dial 1969 REF: 145.022-69 ST EWC: 64158

The Omega Speedmaster 145.022-69 ST represents one of the most celebrated epochs in horology, signifying a pivotal transition for the legendary Moonwatch series. Produced between 1969 and 1971, this reference is the final Speedmaster issued before Omega updated the caseback to commemorate its lunar legacy, making early examples particularly desirable among vintage collectors. It features the iconic stepped 'Medium S' black tritium dial with applied painted Omega logo and the distinctive 'dot over 90' tachymeter bezel, details highly prized in Omega scholarship. Most notably, this reference introduced the Caliber 861 Lemania-based manual-wind movement, replacing the previous column-wheel Cal. 321, marking a new era of reliability and serviceability for the chronograph. The 42mm stainless steel case with classic twisted lugs wears robustly yet with vintage charm, sitting comfortably with a 48mm lug-to-lug and a 14mm profile. Its 50-meter water resistance and domed hesalite crystal reinforce its professional tool credentials. The 145.022-69 bridges Speedmaster's pre-Moon and post-Moon watch eras, encapsulating a critical moment when Omega transitioned from exploratory ambition to celebrated lunar achievement. Revered for its historical significance and unmistakable design, it remains indispensable for serious enthusiasts and connoisseurs alike.
