Abstract

As presented in the previous chapter, there have been many different kinds of escapements. Though, at least 98% of the commercial mechanical watches today use the Swiss lever escapement. In this chapter, the Swiss lever escapement is studied in detail. Its working principle is illustrated and its dynamical model is derived. Experimental validation is also briefly discussed.
