WWII Naval ships

[SusanSusan]

I have a brass ships clock which I am very curious about. I'm told is a zig-zag clock, and it came from a ship that was being broken up on the Tyne after the war. Anyone who can shed any more light on the matter - I'd be very grateful.

Also known as a convoy clock. A ship maintaining a steady course would be an easy target for a U-boat. To make it more difficult for the U-boat to predict the ship's course they would follow a zig-zag course. Ships were fitted with these special clocks that would close an electrical contact at intervals and cause a bell to ring thereby indicating it was time to alter course. I believe examples in good condition with all the electrical bits inside are quite rare.

If yours needs repair the British Horological Institute [01636 - 813795] can supply names of approved restorers in your area.

The National Maritime Museum at Greenwich can probably supply more information these clocks.
