Seiko 6139 Watch Review
Wednesday - 15 February 2012
An avid watch collector has discovered that the Seiko 6139 was the first automatic chronograph in space - confirmed by the astronaut that wore it.
It was widely believed that the Sinn 142 held this record but David Bruno had heard claims that the Seiko model had been worn by an astronaut on an earlier space mission.
Bruno contacted Col. William Pogue with his questions and received detailed replies that included letters photographs and even the original sales receipt for the watch.
The letters confirmed that Pogue had worn the Seiko without official NASA approval on the Skylab 4 mission in 1973. He explained: 'I had been using the Seiko for well over six months (perhaps over a year) and had found it very handy for timing engine burns in the simulator.'
