What's wrong with my 18238?

I started over at the tech forum, but thought I may get more information by posting this here.

I have a new to me 18238 that has an issue. When I set the time and the minute hand is turning, the stem (?) seems to skip and click and the minute hand stops turning temporarily.

I will have to take it in for repairs, but I am curious if anyone knows what I may be looking at. Minor? Major? Is the stem broken or is it some gear?

Here is a 45 second video of what the watch is doing.

Sorry, I couldn't find a way to embed a video. Any feedback is appreciated.

Here's a quick pic of it on my wrist. I was so excited to receive it but now I have to wait to get it repaired.
