The Wishing Fish Clock in the Regent Shopping Arcade, Cheltenham, may be the world's tallest mechanical clock. The vertical distance from the duck to the fish is 14 metres. It weighs 3 tons. On the hour the fish that is suspended under the clock revolves and blows out bubbles.
The famous "Wishing Fish Clock" was designed by Cotswold artist-craftsman Kit Williams, author of the book "Masquerade", and built by Cheltenham clockmakers, Sinclair Harding & Co. The 45 foot high clock was unveiled in January of 1987, costing £80,000. It is believed to be the worlds tallest mechanical clock, weighing in at just over 3 tonnes. Every half hour, the magical performance of the bubble-blowing clock brings the arcade to a stand-still, fascinating young and old. Jumping up and catching a bubble will grant you a wish.
