Seiko Kinetic 5M42-0B09 with possibly a capacitor issue

[Carterlil21]

I have a Seiko Kinetic from the mid 90's. I got it second hand. The case seems to be in great condition, so either little wear or the watch was well looked after, or it was not worn a lot. 

When spun, the watch will begin to tick, but it will only tick as long as it is being spun. Sometimes, it doesn't spin even when spun if it is too light of a spin. Seems to hold no charge, or maybe there is something else wrong with it.

Seeing as it is old and a new capacitor wouldn't hurt, I will probably replace it, but I'd like to know if there are any other tests that I could do to find any other issues without manually inspecting each piece? I have done very little work on kinetic watches, so I am not all too knowledgeable.

You only need to replace the rechargeable battery (capacitor refers to the older technology). Many many videos and postings anywhere about that.

That it's only to replace the battery and it will be working again.

It's not a universal consensus that they're no longer called capacitors though, even if its technically accurate. For example if you get the replacement from Cousins, they still refer to it as a capacitor and so be aware of that when sourcing the replacement. Just so you can avoid confusion.

Cousins is  just a re-seller which like many others names them wrong. Seiko and the battery manufacturers calls them "lithium rechargeable battery".
