During the summer, when auction schedules slow down, The Hot Bid showcases world auction records.
What you see: The Bulova chronograph that astronaut David Scott wore on the surface of the moon during the Apollo 15 mission. RR Auction sold it in October 2015 for $1.6 million against an estimate of $750,000. It set a then-record for an Apollo item, a record for an item owned and directly consigned by an astronaut, a record for a timepiece used on the lunar surface, a record for any Bulova watch, and a RR Auction house record for the most expensive lot that it has handled.
