HEUER AUTAVIA 7863 Vintage Chronograph

 This Heuer Autavia "30 Dato" reference 7863 is the first Autavia with a date function,
The case is beefed up to 40mm from a 38mm case in the earlier Autavia models. An other major difference: In 1968 Heuer adopted a snap-back compressor case, in which the caseback was actually controlled by the surrounding water pressure.


Overall, the watch is in very good condition. The dial is clean, original tritium has aged to a yellow.
The watch is in running condition and the chronograph is starting, stopping, and resetting correctly.
