I tried removing the battery with the prying tool as instructed, but I think it may have slightly damaged the outer black plastic wrapping of the battery. Does this mean the battery is now damaged and needs to be replaced? Or is that just a cover around the battery and it doesn’t matter? I just don’t want any battery chemicals leaking out. Asking before I stick the screen back on the watch, I’ve done all the rest and it seems fine otherwise.
There is, but it is way too complicated… involves using a thin wire to separate the digitiser (touch screen) from the lcd display which is very labour intensive, then using a special laminate, which you can get, but then also you need the industrial machinery to bind them together… this is why even though I have the exact same problem as you I am thinking of replacing the whole screen with lcd. I will post a reply here if/when I am successful!
