Bulle Electric Clock Under Glass Dome

Partially verified

This antique electric timepiece by Bulle is dated by the dealer to circa 1920. Supported by a circular wooden plinth with stepped mouldings and feet, the clock features a tall brass tubular column beneath a tall clear glass dome. The white ring dial displays black Arabic numerals and bears the Bulle trademark below twelve o'clock, with an open center revealing parts of the motion work. Below the dial, the pendulum incorporates a cylindrical electromagnetic coil that swings along a curved horizontal bar magnet mounted on the wooden base.
