C.1960, English, "Rolling Ball" Clock.

C.1960, English, "Rolling Ball" Clock. The power supplied via a large fusee; the timekeeping governed by a steel ball rolling on a grooved table, releasing a latch at the end of its travel, allowing the train to advance while the table tilts toward the opposite end and the ball re-traces its original path in the other direction. The time is indicated on three elevated dials, minutes in the center, hours to the left and seconds to the right. With a sturdy plexi-glass cover and a polished black marble base; very high quality throughout. Height of clock 14", with cover and base 17".
