I am not with NASA either, and I don't think I have been unfriendly as I happen to disagree with my friends pretty often.

I believe your video evidence, while interesting, is flawed by the fact that it is showing a single movement that, as far as I know, has never powered a watch sent to space. A more interesting observation could be made with a Lemania 5100 movement which has been used on many orbital missions, most notably by the Russian Space Agency.

It is also to be noted that the ETA 2894-2 has, due to its bi-directional winding ability (absent from the aforementioned Lemania), a stiffer rotor than on most watches, making it a lot more dependent on gravity than many other automatic calibres. So your demonstration has at the most demonstrated the poor suitability of that particular movement for space travel. I do not think drawing universal conclusions from you little experiment is scientifically valid though...
