This is an interesting example of an electric wall clock dating from the 1930/40s. When new, these Brillié clocks could be regulated to an accuracy of +/- 1 sec/day.
The pendulum drives the motionwork by an electromagnetic system, powered with a 1.5V battery.
The half second pendulum with Invar steel rod was specially constructed to avoid variations in temperature. It has a large bronze spherical bob over a curved magnet.
The rectangular glazed oak case has two clips at the top to affix it to the marble slab on which the movement is mounted, which itself fixes to the wall by way of a metal strip.
The perfect 9-inch dial is signed Electrique Brillié, with Roman numerals and subsidiary seconds indication.
Large bold matching steel hands.
