An amazing opportunity to have your vintage VC piece examined by a member of the heritage dept. He noted movement and case numbers, made a quick phone call to Geneva and a couple of minutes later confirmed that my father's watch was purchased in Sydney in 1964. That made sense because my father was given this watch by a distant relative who had moved out there in the 1920's. It's a Ref 6394, as Tick-Talk identified a while back. Cal K1072. A certificate will arrive from Geneva shortly confirming all this - a wonderful gesture from VC to its vintage watch owners.
Nice to meet Lucy from VC UK and of course Alex. Many thanks to VC heritage dept in particular
