Omega Speedmaster – Reference 145.012-67 – Caliber 321 – 1967

An iconic Omega Speedmaster Reference 145.012-67, powered by the legendary Caliber 321, presented on a leather strap with an original Omega pin buckle, featuring an older service bezel — a classic and honest example of one of the most historically significant Speedmasters ever produced.

We are pleased to offer this exceptional Speedmaster 145.012-67, a reference that occupies a pivotal place in horological history. Produced in 1967, this model represents one of the final Speedmasters fitted with the revered Caliber 321, Omega’s column-wheel chronograph movement that accompanied astronauts during the golden era of space exploration.

The 145.012 is notably recognized as the reference worn by astronauts during NASA missions of the late 1960s, including the Apollo program. Its asymmetric 42mm stainless steel case with integrated crown guards embodies the unmistakable Speedmaster design language — purposeful, robust, and perfectly balanced on the wrist.

Fitted with an older Omega service bezel, the watch remains true to its tool-watch character. At its heart beats the legendary Omega Caliber 321, a movement based on the Lemania 2310 architecture, celebrated for its column-wheel construction, technical refinement, and enduring reliability. The Cal. 321 is widely regarded as one of the most important chronograph movements of the 20th century and remains a cornerstone of Speedmaster collectability.

Presented on a high-quality calf-leather strap with an Omega pin buckle, this Speedmaster offers both vintage charm and contemporary wearability. The combination enhances its versatile character — equally suited for daily wear or a curated collection.

The Reference 145.012-67 stands among the most desirable vintage Speedmasters, representing the culmination of the Caliber 321 era before the transition to the Caliber 861. Its direct connection to the space race and Omega’s role in NASA’s missions cements its status as a cornerstone model for serious collectors.

“Historic, mechanically significant, and eternally stylish — this Omega Speedmaster 145.012-67 with Caliber 321 is more than a watch; it is a tangible piece of space-age history and one of the purest expressions of the Speedmaster legacy.”
