MoonwatchUniverse collection has a dozen photos showing Air Force pilots & backseaters wearing Heuer Autavia during the latter stages of the Vietnam war in the early 1970s, but we'll focus on spaceflight instead... 50 years ago an Heuer Autavia chronograph at NASA... as between 1972 & 1982 well-known NASA astronaut & physician Franklin Story Musgrave wore an Autavia chronograph. In 1967, Story Musgrave was selected as a NASA astronaut and after completing flight training he started as a backup for the Skylab space station program. Already in 1972, Musgrave conducted cardiovascular research for spaceflight laboartories, a week-long simulation which was repeated in January 1976 as the Life Sciences Spacelab Simulation Mission II. He wore his Heuer Autavia 11630 chronograph with Tachymeter bezel during both simulations and in the early 1973 Skylab backup crew photo! Musgrave is the only astronaut to have flown on all 5 Space Shuttle orbiters and retired from NASA after 30 years, in 1997. (Photos: NASA) .
