k, you might stop into, or call, NW Art & Frame in the Junction, and see if they have a replacement clock movement, that will work with your clock.
Years ago, like probably 20 or so, I replaced the movement in one of those wall clocks that is also basically a framed photo.
Now, the one I bought, was a AA, or perhaps AAA battery one, but it might be worth a shot.
I believe I bought it at an Arts/Crafts store, quite possibly NW Art & Frame.
One caveat though, that I didn’t think to consider, was the shaft from the movement, that runs through the clock body, and which the hands mount on was noticeably longer in the new movement.
No big deal in my case, it just kinda drove me nuts until I got used to it.
The part I’m talking about, looks pretty much like this:
