I‘m new in the world of vintage watches and recently found my grandfathers Heuer watch in a box. He bought it in the mid-late 60ies and it rarely left his wrist- explaining the not so nice cosmetic condition. However, the watch works fine, and I really enjoyed wearing it the last couple of days.
My question to the experts here: After reading the infos on OTD ( really great site!) I think I have somthing like the Autavia Ref3646 Andretti , with screwback case and Autavia imprint on the back, however, while the dial is (to my eyes) identical, there is no Autavia signing on the dial. From my google search I have not found an Autavia dial without Autavia signing,
Is this known or is this watch one of these Economy Models?
Serial number is 84xxx, this should fit to the Andretti, right?
Thanks for your help,
