Bulova 30 Jewel Self-Winding Watch (Commander E)–Sold

I decided to branch out a bit from my Elgin collecting.  To that end I bought a Bulova automatic with 3o jewels.  Beyond that, I know little else about this watch.

Update:  Thanks to Hawk53 at Watch Talk Forums, it seems it is a 1965 Commander E.  And from Oliverb I learned that the code on the back, M5 dates the watch to 1965 as well.  Apparently there is matching code on the movement.  I’d check that, but I can’t get the detachable stem to come apart.
