I don't know if this has been posted at any other time, but I was listening to a radio show the other day, (stand up with Pete Dominick) on Sirius XM, and he had an astronaut on. His name is Chris Hadfield and he has posted several youtube videos that are shown in schools about life aboard the ISS. Anyway, one of the videos is about how his watch wobbles around in zero gravity (he doesn't have it fitted very well for his wrist), and someone mentioned in the comments that it is an Omega X-33. I googled it and this link came up. Gen 1 and Gen 2 X-33 – I Already Have a Watch. Its an excellent article about the history and testing of this timepiece and I thought would be an excellent topic for our discussion.. Enjoy!
