- The history of the Speedmaster dates back to 1957 when it was initially introduced as a chronograph designed for sports and racing. However, it wasn't until the 1960s that it gained widespread fame for its pivotal role in space exploration. Since then, the collection has expanded to encompass a wide range of variations in terms of materials, complications, and sizes. In 1985, Omega made a significant decision to launch a Speedmaster variant that incorporated an elegant complication befitting the collection's rich history: the moon phases.

- The reference 345.0809, being the first Speedmaster Professional to feature this particular complication, stands out with its special sub-dial design where all the calendar numbers face towards the center. With a relatively brief production span of only three years, approximately 1,300 pieces of this model were ever manufactured, making it exceptionally rare and highly sought after by collectors who affectionately refer to it as the "Speedymoon."

- Retaining the iconic aesthetic of the original Speedmaster Professional, the case boasts elegant twisted lugs and houses the Lemania-based movement calibre 866, an upgrade from the renowned and robust calibre 861. Furthermore, this timepiece is offered in excellent condition with the correct “1450” bracelet and “808” endlinks, also showcasing a captivating large moon phases and aged creamy lumes that exude vintage charisma.
