I am using tg-timer to time an Unitas 6340. The ebay seller said it was serviced. Apart from the slow rate, it actually looks pretty good. However, I noticed some subtle problems with the waveform of the graph. First, on the bottom panel, there is an extra noise detected. According to this, something is glazing in the balance. Second, in the middle panel, right before the pallet locks the wheel, there is an extra noise. Does that mean the balance is hitting something it's not suppose to?
I am new to watch repairing so I am wondering if I am reading this graph right.
