Closest model I've found to this, although not sweep second, of course, is the Squadron L.
Can you confirm the M6 on case and movement?
Yes, it's M6, absolutely. Extra case pictures uploaded.
Look at the first ad posted under "New Bulova Watch Ads 1960-1969". Looks like the "Sea King AK."
Many SK "AK" ads, very good ad match.
Hello Hab, welcome to myBulova. Nice old Bulova watch. I agree with a Sea King AK ID.
Certainly looks like a Sea King; but I am not sure about the "AK" variant. When I look at the handful of ads for the AK they all show the luminous dots on the inside of the markers (subj watch has them on outside) and the smaller markers do not appear flat (subj watch looks flat).

By golley, you are right Andersok. Good job of noticing that detail. This one is going to require more researching.
Wow, nice result, fellas. I'm waiting for the watch to arrive and will need to do some mechanical restoration work (broken balance staff, missing stem, etc), as you can see. But the markers are, I believe, pitched and not flat. But the lume is certainly on the outside of the markers, as you rightly point out.
Thanks so much for your work on this!
I also agree with a Sea King AK ID.
