AK10 Military

I picked up an AK 10 and A a Bulova A-11 case. Couple of questions.

1. Does the A 11 case have an "O" ring or gasket for the case back?

2. How do I remove the stem/crown from the movement?

3. What crystal does Bulova the A-11 case use?

4 / 5  - does anyone have the "O"ring (if needed) and Crystal for sale??

Stem removal is just the stem set screw, but I can't get it to turn. Any suggestions to losen it without damage. Was going to try a mini-drop of oil, but not thrilled with doing that.

The screw you're referring to is the set lever screw. If it won't loosen it probably has rust on it. A little penetrating oil might help loosen it but you will have to remove the hands and dial and oil it from the face side of the watch where the screw threads are.

I screwed up again.......

Got the set lever screw loose enough to get the stem out. Did not remove the screw entirely. I pulled out and removed the crown/stem. Now I get the stem all the way in, but after tightening the set lever screw the stem just falls out. What did I do wrong - how do I fix it??

Was there signs of rust on the stem Ken? If so, the set lever is probably rusty also and it has a little pin in it that fits into the groove on the stem. If that pin was rusty it has probably deteriorated to the point that it will no longer engage in the stem slot enough to hold it in place and you will have to replace the set lever.

Even with a perfectly clean setting/winding system, replacing a stem isn't completely a walk in the park. If you push too hard or tighten the setting lever when the stem is in the wrong position, you could bend the setting lever or shove the yoke out of the sliding pinion, and either situation will require the removal of hands and dial. This can happen even with some modern movts.
