Haven't opened this one yet. It measures 30MM or so across Runs and keeps time. Looks like it was never carried; and is on the original 12" lapel chain as shown in the linebooks. Second, hr and minute hands are silver. The darkness on minute and second hands is reflection of my camera.
Last photo shows it as pictured in the linebook with it's chainless cousin, the Trylon.
