Autavia 7863c Dato
Heuer extended the Autavia range in 1968 to include a date feature with the launch of the new 40mm compression case. The Autavia 7863c Dato is a manual wind two register chronograph with date powered by a Valjoux 7732 movement. Examples can be found with plain pushers (early) and fluted pushers (later) as well as one of the three bezel options namely H, MH or T.
