OK we all know there are many...but for the sake of this post the other one is..... Rolex GMT 1675 worn on Apolo 14 by Edgar Mitchell. 1971 https://www.hodinkee.com/articles/b...eference-1675-on-apollo-14-launch-day-in-1971
That's not the other watch worn on the moon. It was a Bulova. Also the only watch worn on the moon in private hands. The only non speedmaster worn outside.
I actually did know other astronauts took other watches up and that Rolex was on the moon ( can't remember worn by whom) but it's cool to see the pic
I guess. Not sure. Obviously they all had their own watches and then the Nasa watches... A little like the Explorer and Sir Edmund Hillary
