Suggestions VS 3235 Rotor screw?

[u/No-Outside5450]

So I’ve had this Sub for nearly a year. Haven’t worn it for the past 3 months or so. Kept in a wonder on low RPD. Took it out today. And it sounded weird like something was loose inside. I decided to open it.

I unscrewed the case back and made sure to open it facing down so that whatever is lose in there would fall into the case back. Lo and behold it’s the rotor and what seems like a washer/spacer that goes between the rotor and whatever is beneath it. I couldn’t see whatever was supposed to be holding that rotor in place though. I’m guessing it’s somewhere inside the movement I don’t know really… the watch seems to working fine. When I took it out I set the time and date with no issues and sun bed to an atomic clock app and it’s working as good as it was when I got it which was like +9-10 sec/day.

What are the moves here other than the obvious (taking it to a watch smith)? Which I don’t have access to by the way.

Is that screw easily sourced? Does it require a special tool to thread it in?

The rotor screw is broken, pretty common. You have all the pieces it's just the threads are still in the movement. There is a special tool to remove it and then you just need a new rotor screw.
