"NASA began using the watch. Omega only found out what NASA had been doing with their watches in April 1966, well after Edward White was the first American to "walk in space" (wearing a Speedmaster on the outside of his suit). To commemorate its success at NASA, Omega added the word "Professional" to the title of the Speedmaster in October 1966. "
