It was Albert Pellaton who was appointed as IWC's new technical director in 1944, who led the development of IWC’s first automatic watch. The 'Ingenieur', which translates as 'engineer', was originally launched as a 'tool watch', fitted with the calibre 81 or 85 (later the 852), an automatic movement which was housed in a soft-iron inner case for protection against magnetic fields. This calibre was their first two-directional automatic movement and was used by the manufacturers until the mid 60's. According to the serial number, this particular watch is one the earlier examples from 1955 containing the correct calibre 852, and the original ‘Arrow Logo,’ a Swiss thunderbolt icon indicating dangerous electrical currents.
