In the meantime, here are images of clocks Erika built at the Arcadian Clock Co.
This skeletonized timepiece features an engraved aluminum dial with shaped torch-blued hands.
The Arcadian R Astronomical Regulator features a split impulse deadbeat escapement with sapphire pallet jewels. Each face of the steel escapement wheel has been polished to a high finish.
This 2/3 second pendulum adjusts for temperature differences through Garnier's "dumbbell" system of bimetallic compensation. As the central steel rod expands with an increase in temperature, the brass side rods extend further, raising the pivoted compensation weights. The weights can be moved to adjust the compensation. The solid brass beat scale is a separate element, engraved on the pendulum circumference.
This suspension detail highlights .001" machining accuracy and hand-lapped finishes. The whimsical keyhole opening for the verge is a functional flourish for an otherwise serious clock.
