I was at the Houston Museum of Natural Science with my wife and kids today. We were looking at the mercury exhibit and my oldest son that annual shouted out that I should look at a watch. Check out these photos I guess this isn't a 3570.50
Looks like a later serial 145.022-69 or a-71 (DNN bezel w/ stepped dial)? I think the Mercury missions ended in 1963 or 1964.. I wonder why they chose the Speedmaster that they did?
I'm fairly certain that this particular part of the exhibit pertains to the Gemini missions, as the suit is a Gemini-era EVA suit.
Makes sense, although Gemini also ended before that watch was made I think. Regardless, it's always neat to see how they wore them on the outside of the spacesuits. Pretty harsh environment.
maybe the answer is as simple as the museum didn't want to spend the extra money and knew most people would not know the difference..
So, I'm friends with one of the head guys at that museum, showed him this post, which gave him a chuckle (non-watch guy). He agreed to humor me and get me the serial number off the watch! Give me a few days --he said I could post it. Then the speedy experts here can dissect away for kicks.
Fyi: The display was created and on loan to the museum by nasa. The museum didn't design or create the display. Museum records list the watch, but do not list a serial number. My friend is trying to see what he can do to assist us watch nerds with the actual serial number. Are you guys still interested?
