Admiralty Pattern No. 6 Stopwatch in Hitchin
Circa 's and in full working order. These stopwatches calibrated to 6 secs and yards so that submarines and submarine hunters could measure distance from asdic (sonar) returns to target. This has serial numbers but no military markings or makers name on face, although the clues point this to being a Lemania, due to 'swiss made' on very edge of face at 6 o'clock, hinged rear case cover and the type face and positioning of the numbers. It does have a name and number scratched on the back and intriguingly '21 jung', 'jung' as far as I know is a german word???? Any military history sleuths out there?
