RR Auction is currently in the middle of auctioning off hundreds of pieces of space and aviation history, and one of its most interesting lots is an Omega Speedmaster worn by none other than Gennady Padalka, a Russian cosmonaut who currently holds the record for most days spent in space (879, if you’re wondering). This specific Speedy was worn by Padalka on his 2012 trip to the International Space Station, where he spent a solid 125 days in orbit. The watch even spent close to six hours in the vacuum of space when Padalka left it in an airlock during his ninth spacewalk.
To confirm its legitimacy, the watch comes with two letters of authenticity signed by Padalka and is accompanied by the original box labeled with his name. The watch itself comes affixed to the same velcro strap used to affix the watch to the outside of Padalka’s space suit (it comes with the original OEM bracelet, too). As of writing, bidding sits at $5,363 with just two days to go. If you’re interested in a piece of space history, it’s not too big a premium on what is already an excellent timepiece.
