Below is an aggregation all of the Heuer Autavia 3646 I have found with 1st Execution dial and 2nd Execution hands, with either a 30 minute or 45 minute recorder. If you see any duplicates, errors, have serial numbers to include, or know of other Heuer 3646 to add with a 1st execution dial and 2nd (or 3rd) execution hands, please let me know.

Ranges I have seen for the Heuer 3646 with 1st Execution hands and 2nd Execution dial: 48872 – 52495, corresponding to roughly 1962 – 1963. The serial number is engraved in between the lugs at 6 o’clock.

The range above is extremely limited due to few of these pieces available, and some without visible caseback images, or text, and many without serial number provided.

The watches represented on each row in the table below are intended to be unique, though given serial numbers are often not shown for images, the same watch may appear multiple times. I do my best to use visual cues to pair the same watch posted at different times. When the serial number can’t be established, I give the timepiece a unique ID (based on any part that is known, plus a related date posted).

Unfortunately, some images may not appear below as the table refers to the source page for the specific piece. If the image is removed or if the table is not able to process the site, a broken (or no) image will appear.

Caveats:
Description of pieces are generally based upon public images/video. For some detail, I do not have images and have to rely on text descriptions from the individual posting the timepiece. Some elements are often difficult to determine from pictures, including color of hands, for example if the register hands are black or blue. If I have a 50-50 guess, I leave the detail as “unknown.”
