Checking if amplitude is above a certain threshold and checking for beat error will definitely help but at my watchmaker you still have to remove the caseback to do this (especially on divers with thick casebaacks like the OS
) so I will try it on a hit or miss method first then check it on the timing machine when I go to do the vacuum test
...at least that's what I thought..
I will adjust slightly once per day then time it to a datum to check what is the daily rate...
When men build lives from honest toil...courage never fails
