Model: X10 Chronometer Escapement
Versions of this escapement were invented by Le Roy, 1752, Arnold and Thomas Earnshaw. One of the key features of this escapement is the use of an elastic beam to release and lock the escape wheel. According to Grazley, the chronometer is one of the most accurate of all escapements. The design of the escapement in this model is attributed by Reuleaux to Urban Jurgensen.
