"The ‘Zig-Zag’ clock was used for ships in convoy on an attempt to avoid torpedo bombing as the ships continually zig zagged. They required a signal to tell them exactly when to change course, these Zig-Zag clocks would have been kept on the bridge and every time the bell rang as the minute hand passed the contact this was the signal to change course. The whole convoy would change direction in unison so as to avoid collision. This made the ‘Zig-Zag’ clock a very important tool in the war at sea." * summary from British Antique Dealers.
