Did NASA astronaut/physician Serena Aunòn-Chancellor wear the first Omega Seamaster in space ? It looks like Dr Serena Aunòn-Chancellor wore a two-tone Omega Seamaster Professional Chronometer 300m/100Ft on her first spaceflight mission, Soyuz MS-09 in June 2018. As far as we know the first Omega Seamaster worn on a Soyuz launch to the ISS... Serena is a Flight surgeon and her first space mission as a member of ISS expedition 57 lasted almost 200 days onboard the International Space Station. As a licensed amateur radio operator with callsign KG5TMT, she was the last female astronaut to have made random ham radio contacts from the ISS. Aerospace medecine is an important field of research in order to prepare for long-duration spaceflight mission to the Moon & beyond! (Photo: NASA)
