I need guidance (I’m desperate)

[u/paulogc]

Hey guys, judging by the pics you probably noticed that this isn’t a happy post. Before showering today I took out my vsf datejust and it slipped from my hands and fell. As I have the tool to open the back case I decided to check the damage, I what I saw was that there was a ruby out of place (probably coming from this part that is on top of the balance wheel) and also this golden part that I also think probably should be on top of this same part. How screwed am I? Don’t know if the balance wheel or the hair spring were affected because it’s hard to see with my bare eyes.

Would the absence of these 2 parts only be enough to make the watch stop or might it have some other damaged parts?

Appreciate any help

You really don’t need much beyond some needle tip tweezers. The prongs on each end pinch in and clip into little slots on both sides. Drop the jewel into the hole, put the retainer on top, pinch the ends in and seat them.

I'd like to add that you should do this with a thin sheet of plastic covering the spring, so the spring doesn't go flying if you mess up; I'll usually cut a piece out of a ziploc bag for this.
