Bulle Electric Oak square Wall Clock, with 15 1/2 inch square case hinged at the top.
The perfect Arabic numeral dial is marked Bulle-Clock Electrique.
The clock is powered by 4 standard AA batteries, contained within the square section regulator.
The pendulum consists of a coil which passes over the curved bar magnet with three poles (North at either end and South in the centre, or vice cersa). As an electrical current is briefly imparted to the coil, it is attracted towards one end of the bar. It then naturally falls back to (and over-runs) the centre, when the impulse is again imparted to attract it to the other end.This movement design was patented in 1920, and during the period 1920 to 1952 it is estimated that production was in the region of 300,000 clocks.
Overhauled and guaranteed for 3 years.
