The 42mm stainless steel case of this Omega Speedmaster retains the timeless lyre lug design that defines the Speedmaster Professional. Its robust construction and angular lines emphasize both durability and style, suitable for the rigorous demands of space exploration as well as everyday wear. The distinguishing feature of this reference lies on its case back, where the words "FLIGHT-QUALIFIED BY NASA FOR ALL MANNED SPACE MISSIONS" and "THE FIRST WATCH WORN ON THE MOON" are engraved in a straight format rather than the radial style found on later models. This engraving celebrates Omega’s pivotal role in the Apollo missions and sets the "Straight Writing" apart as a collector’s gem.

The Dial

The black stepped dial features the iconic tri-compax layout, with subdials for running seconds, a 30-minute chronograph counter, and a 12-hour chronograph counter. The applied Omega logo was replaced by a printed one in this era, signaling a shift in production techniques. The luminous hour markers and hands offer excellent legibility, even in low-light conditions.

The Movement

Inside the Speedmaster 145.022 beats the Caliber 861, a manual-wind chronograph movement introduced by Omega in 1968. Replacing the earlier Caliber 321, the Caliber 861 offered increased efficiency and reliability while maintaining the precision required for NASA’s space missions. Known for its robust construction and outstanding performance, the Caliber 861 is an integral part of Omega’s storied chronograph history.

Historical Significance

The "Straight Writing" Speedmaster holds a unique place in Omega’s timeline, produced during the early 1970s as the brand celebrated its lunar success. This specific case back engraving was only used for a short period, making it a rare and significant reference for collectors. Its direct connection to the Apollo missions and its role in Omega’s evolution solidify its importance in the Speedmaster lineage.

The Omega Speedmaster Professional "Straight Writing" reference 145.022 from 1970 is a true icon of horological and space exploration history. Its distinctive case back, classic design, and reliable Caliber 861 movement make it a must-have for Speedmaster enthusiasts and vintage watch collectors. Whether appreciated for its NASA heritage or its timeless aesthetic, this watch stands as a testament to Omega’s enduring legacy in precision timekeeping and innovation.
