For those interested in learning more about dynamic poising and the adjustment of a precision watch, the best book I know of that’s available in English is “Watch Adjustment” by Hans Jendritzki. The best introduction to dynamic poising, which references Jendritzki’s work, that I’m aware of online is the PDF written by Dewey Clark, here. The importance of the point made above that dynamic poising should only be attempted on a watch that has been properly serviced and free of any mechanical defects cannot be overstated.
