1973 OMEGA Speedmaster Professional (Ref. 145.022-69) "Straight Writing"

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.

This specific example is no exception as you will find that this 1973 Omega Speedmaster professional possesses the rare commemorative case back with straight writing which was in production for less than 3 years from around only 1970/1974. The straight writing case backs were Omega’s first commercial response to the Speedmaster’s involvement during the NASA 1969 Moon landings

The step dial or "Pie Pan" Omega Speedmaster's possess a charm and feel that 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 wardrobe also makes the Speedmaster a good choice for the first vintage timepiece and or a classic daily driver.
