http://www.abc.net.au/news/2015-10-24/watch-worn-by-us-astronaut-on-moon-sells-for-more-than-2-million/6881728An exceptionally rare watch worn by an American astronaut on the Moon has sold for more than $US1.6 million ($2.2 million), a US auction house has reported.
Dave Scott, the commander of the Apollo 15 mission to the Moon in 1971, wore the Bulova Chronograph watch on his third lunar walk after his standard-issue Swiss Omega was damaged.
It is the only watch worn on the Moon in private hands and was bought by a Florida businessman in a frenetic, 12-minute bidding war with a rival in Britain, said Boston-based RR Auction.

The watch exhibits significant wear from exposure while on the Moon, as well as from splashdown and recovery.
