FJ & RD Story Antique Clocks has dated this piece to the 1930s.

The simple movement is fully displayed, the battery is mounted under the base, hidden from sight.
The original painted dial has Arabic numerals and blued-steel hands, it is signed BULLE-CLOCK, BREVETÉ SGDG, PATENTED, FRANCE, the signed movement is visible through the centre cut-out.

This pioneering electro-magnetic movement design was patented in 1920 by Favre-Bulle, and during the period 1920 to 1952 it is estimated that production was in the region of 300,000 clocks.
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 versa).

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.

Condition:
The clock is in very good original condition with the movement fully serviced by our FBHI horologist and in good working order.
There is a small oyster chip to the top of the bevelled glass to the left and right hand side of the case (see the images).
