So far so good

Mon problème

The battery died from age and repeated charges.

Ma solution

I was able to remove the battery without difficulty after carefully following all the steps listed--and will all the recommended tools I purchased from ifixit. Now I'm just waiting on my new watch battery to arrive from an outside vendor, so that I can reassemble the watch again, hopefully as good as new!

Mon conseil

Follow the ifixit instructions methodically and don't rush it!
