Breitling Navitimer Ref. 806 from 1970

Extremely nice Breitling Navitimer ref. 806 from 1970 in untouched and completely original condition. The case is unpolished and is only showing some often-seen traces of unprofessional efforts to open the case. The dial and hands set are in very good to mint condition with some normal oxidation around the markers. The service history is unknown but my watchmaker hast just checked the movement (Venus 178) and it is running perfectly well in all functions.
