So next up the repair of a Bulova movement.
I finally broke down and bought a timing machine.
It shows the watch as - 19 seconds with a beat error of 2.8ms. (hopefully picture uploaded)
But can someone explain to me fundamentally what that means?
This is my guess -----
The 2.8ms is not a problem w/ the going train as that would just slow down the movement entirely... .
It must be a problem w/ the escape or balance wheel????
It is probably not a problem w/ the arbor or the escape wheel as that would affect the movement unilaterally ????
I am guessing it is most likely a problem w/ the pallet jewels or the guard fork???
I just don't understand beat error.
Can someone explain to a novice?
At the end of the day my question is how do I diagnose and repair this problem?
I am having a real hard time understanding and interpreting beat error.
