from what I have been able to touch on, there were 4 watches that went to the moon. they were all issues Omega Speedy's, several wore thier Bulova Accutrons. Swigert on Apollo 13 wore a rolex (still trying to find the model) and Dave Scott brought a Bulova to the moon, and wore it on his 3rd EVA. Bulova has released the watch as a limeted edition - the Lunar Pilot. I now own a Speedy, an Accutron, and this Lunar Pilot.
