Thanks you for sharing. Easy enough to follow. A bit fiddly but took my time and made sure I had a small box to keep the bits in while I waited for the new battery to arrive. One of the springs did pop out (Step 2) but I didn’t lose it!! Reassembled and the watch turns on so all looking good! I think my old battery leaked so I am hoping no internal damage was done and the watch can recharge the new battery.
