In 1968, NASA engineer James Ragan approached Omega with the idea of creating a dedicated “Lunar Surface Chronograph”. Mr. Ragan was the same engineer who oversaw the 1965 tests which selected the Speedmaster as NASA’s official timepiece, and he was therefore very well acquainted with the model. Still, he was worried that the longer EVAs (“Extra Vehicular Activities”) on the lunar surface might prove excessive even for the qualified Speedmaster.
