The Omega reference 105.012-66 was released in 1964 and has been affectionately named the “Moonwatch” as lunar module pilot Buzz Aldrin wore this model on his space mission, which landed himself and Neil Armstrong on the moon for the first on July 20, 1969. The reference was the first to feature the “Professional” signature on the dial and became one of the leading watches wore by NASA astronauts during the late 1960s and early 1970s.

The present 105.012-66 is made even more collectible the fact the cbyase was not made by Huguenin Frères, the traditional casemaker for the Speedmaster but by La Central Boîtes (CB stamped inside the caseback), cases made by CB had flatter lugs. La Centrale Boites made the cases only for this reference.

The present example stands out due to its unrestored nature, retaining its original dial without a trace of intervention and featuring an impressive case fully preserving its original shapes and proportions. The presence of the stainless steel bracelet adds a final layer of collectability and appeal.
