How these movements pass timegrapher test and then arrive doa is beyond me. 7750 brand new Swiss swap would cost almost 1k with labor movement alone costs $700CAD + tax in Toronto
I think in my case a timegraph would not have caught the problem. Since technically the second hand was running. It just was not transferring the power to the minute hand since they were slipping? That's just a guess I have no idea how the time graph works. Someone correct me if I'm wrong.
