Warning! Inserting the screw to the plate that holds down the battery connector and the GPS antenna was very difficult. I actually lost the screw and thought it was down inside the watch. I removed the battery to see if it shake out. I realized that it was not inside the watch. My last hope was looking on the area rug with a big magnifying glass. Low and behold I found it. Tip! Do not try this repair on a bare wooden tabletop. That tiny little screw will bounce a long way if you drop it. You need to work on a soft rubber mat or on the top of the magnetic parts mat that Fixit sells. After several attempts trying to get that screw started, I still failed. Eventually, I had to use the tweezers from Fixit to hold the screw then dab a tiny bit of Gorilla glue on the Y0000 bit and hold the screw with the pliers and push onto the bit until it dries. Once the screw was glued to the bit I had no problem.
