The Omega Speedmaster Professional is by far one of our most favorite chronographs. The Speedmaster has an incredible history starting with automotive racing moving into flight and eventually to NASA and the U.S. Space Program.  There are many subtle differences within the vintage Omega Speedmaster range of references that make them all slightly unique and different.

The very first commemorative Speedmaster Professional that Omega released after NASA’s successful Apollo 11 mission to the Moon is known amongst collectors as the “Straight Writing” model. These short-lived executions were in production between 1970-1974, and feature a commemorative engraving on the case back that reads “The First Watch Worn On The Moon” in straight text, which is where the nickname originates from. Shortly after this “Straight Writing” production run, Omega introduced the medallion case back with curved text which remains in use today.

The step dial or "Pie Pan" Omega Speedmasters possess a charm and feel that the new modern equivalents don't seem to quite have. The ref. 145.022 with the workhorse Cal. 861 movement is clearly built to last. The Speedmaster looks great on the bracelet as well as a handcrafted leather strap. It is one of our favorite chronographs due to its timeless design and functionality. Its versatility to be paired with the most formal and the most casual of wardrobes also makes the Speedmaster a good choice for the first vintage timepiece and or a classic daily driver.
