Runs 1.5x speed - already troubleshot a lot…help!
EB8800 movement. Ran 1.5x speed when I got it. Wanted to trouble shoot and fix.
Demagnetized it already.
Lost the jewel on the balance cock so got a full new balance and hair spring and pivot from another watch.
Pegged the jewel and other part the pivot staff goes into.
Oiled jewel.
Regulated, got beat error down to 0.5ms (though when I close it up, it somehow pops back up to like 20ms when I reopen it).
Regulated again.
And it’s still going 1.5x speed.
I keep moving the regulator arm further towards the stud and still just can’t get it happy.
Help!
