I got this old Abx-24 watch and wanted to replace the battery. At some point I found the small spring on my desk (that's next to the casio logo in the picture). (The little step in it was my fault as I squeezed my tweezers too hard accidentally). It's not the signal spring that connects to the backplate as that ones still in place. Where does this spring go?

It can't be from another watch or anything else on my desk...

Thanks for any help in advance
