still thinking about this mysteries jewel that alludes my mind
A simple solution. A jewel assortment and a Seitz jewelling tool.
It would be better if you reviewed your A.I. queries and then responded here in plain text as to what you have deduced.
Giant screen dumps of A.I. slop are irritating to me.
There's nothing wrong with the movement - what you are seeing is perfectly normal and expected.
Clear jewels are pretty common. Longines used to use them a lot, basically my least favorite part about working on older Longines. I have a longines I just finished on my bench that used clear CAP jewels. Finding jewels in the epilame is hard enough AS IS, but even harder when they are clear!
On a previous watch I did, I lost a cap jewel and spent an hour looking for it because it got stuck to the tip of the tweezers I was using. It hit the light JUUUST right that I could only see it from a certain angle.
And yes, the split in the balance wheel is intentional and common.
You DO once again have a hairspring problem though. Magnetized, dirty, or wrong in some way, it needs help. Rest of the movement is pretty filthy and needs a clean ASAP too though.
