87’ X-Swatch - Repairable?

Hi friends - I found an X-Swatch a long while ago and it’s been sitting around doing nothing. Yes THE coveted xxx Swatch (lol kidding)

I’ve considered sending this somewhere to try to get it repaired but felt nervous to do that.

The time has come - is there any way I can repair this bad boy somehow? I tried replacing the battery and one of the hands sprung to life..looked like it was trying to move then just stopped.

Anyone experienced with this? Should I not risk breaking it?

I really want to wear it as a grail piece (reselling is not an option)

Thank you!

Edit:

Thanks for all your comments so far. I am near NYC if anyone maybe has any recommendations? I wouldn’t be opposed to using the face and rebuilding it or maybe creating a new watch with the face. Thoughts on this?
