Bulova 1962 Jet Clipper

Hey everybody, it’s been a while, but I have another stumper. Automatic movement. Off white dial with Arabic markers marked self winding. The case has no lugs and fits inside an external case which houses the watch body. I’ve never seen anything like it and don’t even know how to remove the case back. No obvious pry points or areas to rotate. F832724 M2 stamped on caseback.  I wish I could provide more information. The watch is truly in amazing condition and I don’t want to try to get it apart to look at the movement. It is working flawlessly.
