Cap Jewel question

[LittleWatchShop]

When cleaning this watch in my L&R spinning machine, this one cap jewel separated from the "holder" (for lack of a better term).  What I have done is just assemble the watch by placing the jewel first and then placing the holder on top and screwing down.

Is that correct?

I don't know, but my, and I'm sure your impression, is that the jewel shouldn't normally separate from the holder. Let's see what the pros have to say about it.

I think that should be a rubbed in jewel.

That will work, but is should be burnished into the setting; but your technique will work.

Pivot is suppose to somewhat protrude the jewel hole before reaching end stone. 

 You now are likely to have the end stone touching cock jewel, hence  have zero  pivot protrusion, as a result pivot would easily jump out of the jewel hole in the event of a shock.

If the end stone doesn't want to stay put,  I try to slightly peen the hole for a tighter fit of the end stone.

No glue whatsoever, I havev seen glued ones as scrap in lots I buy.

Whichever pivot this end stone is suppose to cap, might now be pushed on by the cap as you have installed it, possibly retarding or fully stopping the pivot from turning. 

Another point worth mentioning is that I see all three cap jewels are off, unless marked or some how kept track of, how do you know which one goes back where, you inadvertantly have altered end shake all are three relevent arbours, thats not good watch repair. As you acquire more experience, you would want to check and adjust end shakes on all arbours for a smooth gear train. This is part of what makes watch repair an art as well as watchmaking.
