         Section One Notes
         The first nine chapters are explained without math. These chapters are less complicated, and they introduce the reader to the logic behind the drawing techniques, so as to serve the needs of those who want to learn about escapements but would not be drawing them on their own computers. The tenth chapter explains the math behind the previous chapters. This way the reader has the option whether or not to become involved with the math.

         Section Two Notes
         Chapters 12 to 18 are similarly presented in order to introduce the reader to the logic behind the drawings, though these drawings are more involved and require some understanding of watch theory, such as lock, drop, draw, and impulse. These drawings are not simplified (as in Section 1) and are shown in full detail with full method outline. Chapter 19 and beyond become more involved with the math that is required to create the drawings. The reader who does not want to become involved with the math could benefit from the logic of the latter chapters by passing over the math.
