Danish watch website TimeGeeks (“because stamps are for nerds”) came up with this YouTube movie of an Omega Speedmaster X-33 that is being repaired in zero gravity. To be honest, the Speedmaster X-33 might be a good investment, since they are not being sold anymore. It was introduced in 1998 and only upgraded once (Omega got rid of the shiny bezel and other shiny parts to replace it by brushed ones). Omega discontinued the X-33 in 2006. Ryan Rooney dedicated a web site on the Speedmaster X-33, which is really worth visiting. Anyway, Kristiaan Hagen of TimeGeeks reported this great movie about repairing one in space. NASA astronaut Don Pettit made and published this movie.
p.s. Thanks to Bernard for letting me know about this movie🙂
