One of the highlights of the first ESA ‘Space Rarities’ auction being held on Friday, 12 April 2019, is this flown Omega Speedmaster X-33 Skywalker chronograph watch, serial No. 92115589. This watch is very special in that travelled as one of only five sent by Omega to the International Space Station on board the Japanese HTV-6 space vehicle, launched on 9 December 2016. It stayed on the ISS during ESA astronaut Thomas Pesquet's Proxima mission and returned to Earth on the SpaceX Dragon CRS-11 spacecraft on 3 July 2017, shortly after the return of Pesquet. It has logged 206 days in space including 202 on board the ISS.
