Anyone care to recommend engineering-level books about watches? I've read "Complicated Watches and Their Repair" by deCarle and "The Science of Clocks and Watches" by Rawlings, plus a variety of lesser known books about escapements. These texts are quite old, however, and other than Rawlings book, are more about how to work on them rather than the science behind them. I'm interested in how the various mechanisms work, as well. Anything related to modern micro-mechanical manufacturing would also be interesting. Complex math is not a problem.
Thanks in advance.
