Reply To: Pocket watch running WAY-WAY FAST

Yes that’s definitely a possibility David.
If the new spring is powerful enough to kick the balance amplitude high enough to cause knocking (re-banking) then it could run very fast. A timing machine would reveal a knocking problem instantly but not sure if Watchdogg has or has access to a machine. Another way is to use an amplifier to listen to the ticking. If it’s knocking it will sound like a galloping horse!
Another way to check it without a machine is to wind it a few turns to keep the amplitude down and then check it’s rate.
