Seiko Vintage 6139-6002 'Pogue' Automatic Chronograph from December 1974
All original except for: 1. Crystal which was replaced at service & 2. Bracelet end links
These watches are referred to as the 'Pogue' after Colonel William Pogue who wore his own personal 6139 on NASA's Skylab 4 mission in 1973, the third and final mission to the United States’ first space station. Although the 6139 was never formally approved for mission use, Pogue stated that his operated flawlessly during his time in space where he used it to time engine burns. Pogue said that as he had been using his Seiko during training for up to year before the mission launched, (they weren't issued their Omega Speedmaster's until very late in training) and had grown familiar with the Seiko, he decided to bring it as his trusted timepiece without seeking official approval from NASA
