Perhaps one of the most fascinating timepieces ever devised, the Rolling Ball Clock was patented by Sir William Congreve in 1808. (A copy of the original specification is included with each clock). The basic concept is that the ball takes 15 seconds to run down the zig-zag track where it trips the escapement which reverses the angle of the tray and cause the clock hands to move forward correspondingly. The clock is supplied with a mahogany framed glass case, a green marble base is an optional extra.
