Movement jewels unknown. Last picture is the top of the inside box. Looks close to the "Surf King" listed in one of the posted 1964 ads.

Can't tell from the pics but it could be a 1 piece case which means the back does not come off. The way the engraving lines up on the case back leads me to believe that it is a 1 piece case (unless the last person to apply the back was as OCD as me and took the time to line it up with the case). Check carefully, if the back does come off there should be a small indent where you can get a small blade in. Sometimes the case detail makes it look like the case back is a separate piece. When you pull the crown out to the set position is there any movement side to side or does the stem stay rigid. If there is any play in the stem it may be a 2 piece stem which would indicate a 1 piece case.
I hope I haven't confused you too much.
