Zero gravity watch testing!
I do not know if it has been some discussion about that already, I can't find anything on the forum.
I wonder if the use of mechanical watches in zero-gravity environment need special regulation.
I enclose an interesting article about the testing, but the results are still unclear.

In fact it is known that the gravitational field affects the accuracy of a mechanical watch. From the mathematical formulas that describe the behavior of the real pendulum, this fact is also clear. (Hence the invention of tourbillon). Searching the Internet I have not found explicit opinion. Many agree, and it seems obvious that in zero gravity conditions mechanical watch should be more accurate, but what about the timing (Again, does it need special regulation or not)?
Every opinion from respected members of the forum is welcome.
