1960's Hamilton GS "General Service"

The Hamilton GS ("General Service") was produced from 1960 to the end of 70' for the non-military personnel of the British armed forces and UK government personnel. This specific variation has 'H.S.C 103' stamped on the case back. H.S. Cooke & Co., Ltd was a manufacture of various accessories for firearms during WWII. Specifically producing parts for the Lee Enfield rifles. What the '103' means is a mystery. Since these "General Service" watches were for non-military personal. It can be assumed this watch was for someone within the manufacturing side to help with the war. The broad arrow making this watch even more interesting being on the front and the back.
