Throwback Thursday: Omega Speedmaster Ref.2915 ‘Broad Arrow’

The Speedmaster is, without a doubt, one of the most important and recognizable watches in the history of Omega. However, when this particular Ref.2915 was made in 1958, its true claim to fame was still in the future. That didn't make the Speedmaster any less innovative when it was launched. It was the very first chronograph that had the tachymeter scale engraved on the bezel rather than printed on the dial. This increased the legibility of all the functions and was one of the reasons many professionals embraced it. This would later even include NASA, where one of the successors of this model would make history as the first watch worn on the moon.
