First off, the movie was awesome, and I too couldn't stop looking at the details on the suit. It was a bit fast paced, could of definitely used another half hour. One choice they made really bugged me, but otherwise pretty much perfect.
That's the watch that has come up in a few links in the thread. Felt a bit forced to have it show up there, but now we know what that flap on the right wrist is for. I mean a mechanical watch in space would serve as a backup for electronic failure of the wrist computer, but still. I was hoping he would wear it inside and it would not be part of the suit, but no such luck. Will have to figure something out.
