The installation was relatively easy because the tools packed with the batter were of decent quality and were absolutely correct for the case "y" head screws and the motherboard Phillips screws.

Watch was two years old, so I was hoping it was the battery. It was. The install was a little frustration because I had issues getting the back cover off. The 1.5mm Y screwdriver that comes with the kit didn't do a great job of loosening the screws. Fortunately, I had a second bit kit that had the same size. I was then able to unscrew the back easily, so I am not sure if anyone elase will have the same issue. Once you get the back off, there are a couple of tiny Phillips screws and three ribbon cables that need to come off. You then need to carefully pry the thin cover of the internal casing off to expose the battery and the fourth ribbon cable. You should be able to do this if you take your time. It's not overly complicated but requires a steady hand to get the tiny ribbon cables reconnected. I am happy to report the watch is working perfectly now.
