Some of You OF-members might have heard the recent "social media" rumour that Edwin Buzz Aldrin offered the first watch worn on the Moon to Swiss Science Fiction writer Erich von Däniken in return for the millionth copy of Erich's eternal book "Chariots of the Gods".
Don't know if I can post the image for copyright reasons, so I'll only show the important bit:
.
As I mentioned beneath the photo, looks like a 1969 Apollo XI text caseback, so certainly not Aldrin's Apollo-flown NASA-issued n° 43, which was a 105.012-65 version with Hippocampus caseback. Of course Aldrin owned several Omega Speedmaster chronographs
Some of the early astronauts received 2 NASA-issued Omega Speedmaster chronographs. Normally these had to be returned to NASA as such an extent that Deke Slayton threatened letting them no longer fly T-38 jets as long as the astronauts didn't return their Speedies to NASA as these watches needed a service anyways !
As an interestinf side-note... Post-NASA, 1980s and 1990s, Edwin Buzz Aldrin went through different wrist watch make periods, first we noticed him often wearing
Rolex (GMT & Sea Dweller) and later mid-1990s
Breitling Emergency yellow dial versions !
. just my five cents
