So here is a question to all you folks who do watch repair/renovations. Is there a Timegrapher database that shows known problems in watches and how these can be detected by a Timegrapher. For example, here is a snapshot of a Bullhead 6138 after I regulated it. It’s recent service history is not exactly known, probably sometime in the last 10 years. I fully wound it but the amplitude is a little low and the time would accuracy wander up and down. When it got below 1/2 power it would get a little noisy and slow some.

So this tells me that the gear train is dragging just a bit and that it might be due to get a service in the near future. But nothing bad is happening overall. Is this right? What other issues can be documented? Is this useful?

We should wipe out the descriptions, keep the diagrams and make up humorous statements for each
