Moving your arm alltogheter will mess up the timekeeping.
Not only the position your arm is in.

A lot of people here seem to think that COSC is an accuracy for timekeeping.
That is only true if you dont move the watch. How the watch behaves under movement (something you cant prevent when you wear it) is a whole other matter.
If you regulate a watch with a timegrapher you can see that it can sometimes take 30 sec. or so before the watch is in a resting state that the timekeeping is constant again.
So how you use the watch also determines how accurate it is. If your useprofile is accurate you can regulate a watch to your specific behaviour.
