Citizen movements

Hello.

I was looking to get a Citizen Stiletto (not the blade) as my next watch. I found a few used that are a good price. The only thing I am worried about is what to do if the watch stops working. It is an eco-drive powered model with no day/date which is why I like it. I feel like I'll be able to set it once and leave it alone for a very long time in terms of changing the time/date (because there is no date) and worrying about a battery. I want to get a mechanical watch soon, but for now this would be a good beater watch that is dressier than my G-shock. I found a used one on Ebay that the seller said did not work, and in the details it said Citizen doesn't manufacture the movement for this watch anymore which is what it needs.

Does anyone know the reliability of this watch? The reliability of Citizen eco-drives in general? If it is true Citizen stops making movements/parts for movements even while they still list the watch on their site? Would it be possible to fix an eco-drive if this is the case (may be hard to swap in any movement since it is a thing watch)?

I really like this watch, but if I have to worry about it breaking down and being unable to be repaired, I'll avoid it and buy something else on my list.

Thank you.
