I just purchased a timegrapher and browsed through the threads I could find about them but there is conflicting information about lift angle for American Pocket Watches. I know someone here can lead me in the right direction so here is the question.

The timegrapher's default angle is 52 degrees. On the forum some have compiled various lift angles for American pocket watches to be anywhere from the 40's to the 60's. Some of my watches would fall into those listed but some do not. I would like to time my watches and would like to know where to start. I am not trying to be precise but would like to be right!

Thanks for any help

Use the slow motion video feature on your phone, and wind the watch up until you observe 180 degrees of amplitude. Place the watch on your timing machine, and adjust the lift angle util it reads 180. You now have the lift angle for that watch.

I have a file containing Lift Angles but I have never found much use in it. I'll add it here.
