I know nothing about vintage watches. I typically hang out on the dive watch forum and the affordable forum. A friend of mine brought me a vintage Timex that belonged to his Grandfather. He said his grandfather past away in 1967 and this watch had been locked away pretty much since then. Amazingly, the watch began to run after a quick wind. The only engraving on the case back is "US Time" along with a serial number of A-0325. Anyone familiar with this? Thanks for any assistance you guys can provide.
