Highly important Omega Speedmaster 2915-1, representing the very first generation of the model that would later become the NASA Moonwatch. Produced around 1958, this watch features all the hallmark elements of the earliest Speedmasters: BASE 1000 steel bezel, straight lugs, Broad Arrow hands, and the legendary Caliber 321 movement — a cornerstone of Omega chronograph history. The dial has aged into a stunning and desirable tropical tone, with evenly patinated luminous material offering exceptional character. The original engraved bezel is particularly rare and greatly increases the collectability of this example. A milestone in tool-watch evolution, and an exceptional opportunity to own one of the most sought-after Speedmasters ever produced.
