On an off chance, I went into the used book store across form my office and found this:
The History of the Self-Winding Watch 1770~1931
By Alfred Chapus and Eugene Jaquet English Edition, 1956
First Edition with multiple tipped in illustrations (pasted in prints)
It seems to be systematic study (with lots of reprinted diagrams from diaries and patent applications) of the evolution of first "pedometer" type self winding pocket watches to the rotating mass on stem design of todays wrist watches. At $75 bucks, I think I found a rather nice text.
