Chronometer escapement pendulum clock

Chronometer style escapement is rarely used in clocks. Some time ago I built a 3D printed wall regulator prototype with one second pendulum, but over the time I changed the design to half-second table-top clock - and rather than wight driven using constant force negator springs. The pendulum has a semi kinematic mounting and the escapement (with beryllium copper detent and passing spring) will be fully jewelled. Here are some stages of the construction and the first setup to test the operation of the pendulum and the escapement.
