this is an absolute stunning 50 year old (!!!) Heuer autavia racing-chronograph from 1972. the watch comes on it´s corfam racingband with original heuer shield buckle and it´s box. the whole piece is in unpolished, mint and allover original condition which you will find only very rarely in todays market. the automatic caliber 12 is running exactly and is nor in the need for a service soon. serial-  and reference-number are clearly readable between the lugs of the 42mm steel case.
