This was probably beyond my skill level, but I tried this and it seemed straightforward, but after re-assembly, when I hooked it up to the charge cable, the watch doesn't seem to be charging and won't turn on.

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.

Extra hints:

Step 2 - The red seal can come out with the back - carefully place it back into its slot in the body of the watch before reassembly. It only goes in one way. Not sure about turning it over to be ‘face up’ as the springs will fall out. Move onto step 3 and tape them, etc.

Step 3 - you can tape the springs, but when the motherboard is removed, they can fall out the back. Consider carefully removing them first and setting aside in the matching pattern for easy replacement

Steps 4-6 - all good, but don’t bend those metal clips too much…

Step 7 - consider taking the tape off the front of the battery (+ side) as well and moving to the new one

Step 8 - reassembly of motherboard - carefully compress each corner and feel as each clip ‘clicks’ back into place

Step 9 - place back in housing, making sure it sits level

Step 10 - replace back of watch - a few careful jiggles may be required as there are 6 different springs to get touching at the right places.

Regarding symptoms where the buttons don't work after putting it back together:

The rectangle cutout in the battery tape seems to be important to have in the exact same orientation so that the contacts from the cover can connect with the battery. I solved this by removing most of the tape.

I got in trouble by removing the tape to get the old battery out, thereby losing the correct placement.

Worked beautifully - thanks for this guide. If ericcox1 still checks this, I had the same issue after replacing the battery - cleaning the charge nodes on the watch and charger cable with a Q-Tip and rubbing alcohol fixed it. Fired up as good as new.
