Update: I think this was a failed purchase for the replacement battery and adhesive seal. After placing the finished repaired watch with the iFixit battery on my charger, the watchface seemed VERY warm to me, and soon became almost too hot to even touch.
Shortly thereafter, the charging symbol was replaced by a red thermostat symbol. Now when I put it on my charger, it’s blank and I get nothing from it in the way of a display. So, buyers beware! iFixit, your product and directions have disappointed me!
When I removed the old adhesive, there were to small tabs that extended into the watch batter case. No mention of these tabs, which are shaped like small T’s, anywhere in the repair manual for the Series 1 (original). I’ve just finished my repair (battery replacement and new seal, and have set the watch on the charger. I’m concerned that those two tabs, which I removed with the old adhesive seal, may have been important elements in the watch either for breaking some electrical connection, or making a “tamper proof” type of switch if broken or removed.
When I put the watch on my charger, it did not light up indicating it was being charged. SO, iFixit, you should better document the Series 1 removal of the adhesive seal to address those small “T’ shape extensions into the watch case!
