Nic,
I just re-read your previous post and see that you said the watch is running 30 to 60 MINUTES per day slow. I thought you had said seconds per day.
First off best not to move balance screws to different positions as they were adjusted in the factory for temperature compensation as well as establishing a perfect relationship between the balance assembly center of mass and the balance staff axis. Moving them will change the dynamics of the balance. Also…if you are thinking of buying a timing machine so you can determine whether or not the cannon pinion is loose or slipping, there is a very simple way to do that without a machine. If you would like an explanation of how to go about it let me know and I’ll put it up here.
