The Apollo 15 third excursion lasted 4 hours, 49 minutes and 50 seconds. There are images of him wearing this watch, when he saluted the American flag on the Moon, with the Hadley Delta expanse in the background. The Bulova Chronograph Model #88510/01 that Scott wore on the lunar surface was expected to fetch more than $1 million, as it is the only privately owned watch to have been worn while walking on the lunar surface. So, during his third lunar walk, he used his backup Bulova watch. Transcripts from the Apollo 15 Lunar Surface Journal attest to the fact that during Scott's second excursion on the Moon's surface, the crystal face on his Omega watch had popped off. Those watches are deemed to be government property. All twelve men who walked on the Moon wore standard Omega Speedmaster watches that had been officially issued by NASA. In 1971, a Bulova chronograph was carried on board Apollo 15-the fourth mission to land men on the Moon-by mission commander David Scott. In the 1960s, the company was involved in a rivalry with Omega Watches to be selected as the 'first watch on the Moon'.
