Movement Assembly
Spring-driven movement built on a jewelled plate: a fusee equalises the mainspring torque, a spring-detent escapement frees the balance to swing almost unimpeded, and a compensation balance corrects for temperature. A full specification article for this item is being written. Meanwhile its bill of materials and connections are below.
