The Omega Speedmaster 145.022, launched in 1968, introduced the robust and easier-to-produce Caliber 861, replacing the legendary 321. It became the workhorse of the Speedmaster line for over two decades, accompanying astronauts on numerous missions after Apollo 11. Today, it’s prized for its durability, its strong ties to space exploration, and its vintage aesthetics, especially the tritium patina. 

 This watch is one of the most iconic models in the famous Speedmaster collection. Launched in 1968, this reference marked a significant transition in both movement and design. It’s highly sought after by collectors for its links to space exploration and its role in continuing a legendary series of chronographs.

 The 145.022 represented a technical leap from earlier models, replacing the column-wheel Caliber 321 with the cam-actuated Caliber 861. This movement, developed by Albert Piguet of Lemania, was designed for easier mass production while retaining precision and robustness. It beat at 21,600 vibrations per hour—higher than the 18,000 of the 321—improving stability and timing.

 The Speedmaster 145.022 blends technical innovation, space heritage, and timeless design. Well-preserved examples with original tritium dials, vintage tachymeter bezels, and correct case backs are especially sought after. Each variant reflects a chapter of both space exploration and horological history.
