Import Code YXY Calibers

Elgin National Watch Company (Elgin, IL, founded 1864) produced over 40 million movements at its peak. Beginning in 1953, it began importing Swiss movements (initially FHF calibers 643, 644, 645) because it could no longer produce American watches cost-competitively against Swiss and Timex. Swiss self-winding Elgins were imported from 1953 until the 762/761 Durabalance automatics arrived in 1960; Swiss imports continued through the company's final years in the mid-1960s.
