Theory of clock, watch and chronometer escapements is important and interesting part of theory of mechanisms and kinematics. Despite the fact that chronometer escapements are invented in past times, from the viewpoint of kinematics and machine theory, these mechanisms represent the jewel treasuries of knowledge and engineering wisdom. This paper considers and discloses operational principles and constructive geometry of Thomas Earnshaw‟s chronometer detent escapement. Moreover, process of 3D solid modeling, and assembling of all escapement parts, as well as the motion study and simulation of escapement operational cycle are presented and explained. This analysis and considerations enlighten not just the kinematical properties and characteristic of one particular chronometer escapement type, but also clarify and illuminate the process of computer aided mechanism design, construction and motion analysis.
