Note 5 — The Invention
Reading edition
Those who have seen the Waterbury watch, which developed from this design, may be drawn to the conclusion that this explains why it took so long to wind the Waterbury. Such is not really the case; in the Waterbury the winding wheel (which is on the outer rim of the barrel) was nearly as large as the inside diameter of the case while the pinion engaging with it was of only nominal diameter. This meant that one turn of the winding crown wound the barrel a much smaller fraction of a revolution than in a watch of conventional design.
