As the story goes, Dave Scott's Speedmaster became damaged and the front crystal popped off, which necessitated he wear his back-up Bulova. Colonel Scott went on to walk on the Moon's surface and was the first person to operate a lunar rover vehicle. One his wrist at the time was reportedly the Bulova watch. After the Apollo 15 mission, the Bulova watch - as it was Scott's personal property - remained his personal possession for many years. In 2015, Scott himself decided to auction off the Bulova watch, along with a few other items he had on the Apollo 15 mission with him. The price achieved for Dave Scott's "Bulova moon watch" was a staggering $1,625,000 in late 2015.
