Thanks. You can take e.g. the Watch Tuner Timegrapher App which uses a headphone as microphone. A bit tricky due to the mic. installation in different watch positions and external noise. I tried that too and it works to get a first idea, not as stable as a timegrapher but therefore much much cheaper.
The scatter of some data points on the above Watch Tuner Timegrapher figure have nothing to do with the watch movement, their are noise induced, which can be improved, for sure.
