Astronaut chronographs... onboard Skylab space station Did You know that the NASA-issued manual-wind Omega Speedmaster chronographs were part of the medical research onboard NASA’s first space station? The research into radiological protection and medical dosimetry for Skylab crews encompassed two areas; expected radiation and unexpected radiation exposures. The Omega chronographs were listed in the onboard radiation sources. Moreover, each of the Skylab astronaut carried a small dosimeter, which some wore on the velcro strap of their Omega Speedmaster wristwatch. (Photo: NASA SP-377)
