Speedmaster Professional Moonwatch question
I've tried to find the answer to this, but it looks like my searchfu is not all that strong.
To the best of my knowledge, the 321 movement is the Speed that passed all the tests. But by the time of the 1st Moon Landing, Omega had upgraded the movement to the 821 (I think that's the number). Did NASA upgrade to the 821 by then, or did they still use the 321? Also, did the 821 movement pass all the same tests? Thanks for any help you can provide.

"The watches used for Apollo 11's mission were the 1967 "pre-Moon" 321 versions."
All of the early Speedmasters used the same Calibre 321 movement, which was only replaced in 1968/1969 with the introduction of the Calibre 861 movement, used in the "Moon watch".
It looks like Apollo 12 and all the subsequent missions used the 861.

Yep, my 105.012-66 was a 321
Already answered but I think they used them all and continuing to do so.
