Family: ETA
The Wittnauer 11SR is a manual-winding ebauche based on an ETA caliber, produced during the 1960s. Wittnauer served as Longines' U.S. distributor, and some watches bearing this movement were fitted with actual Longines calibers. The movement is not in-house, reflecting Wittnauer's role as an assembler rather than manufacturer. It was discontinued in the late 1960s.
