Released by Seiko in 1969, the 6139 was the first automatic chronograph movement on the market (although it was overshadowed for a number of reasons). If that wasn’t enough, in 2007 it was discovered that the 6139-600X series was worn on a 1973 space mission, making it the first automatic chronograph worn in space by a margin of 12 years. It turns out that Colonel William Pogue had purchased his gold-faced 6139-6002 at the PX on base, and after training with it for over 6 months, felt more comfortable with his Seiko than the NASA-issued Omega Speedmaster.
