Thanks for posting this … I figured this had to be a relatively easy thing to do (e.g., you’re basically replacing a coin-cell “capacitor” instead of a traditional watch battery) but I was amazed at how many online comments I read suggesting that this procedure was somehow “too difficult,” or “not worth it” for Eco-drive watches. My guess is that the only thing that would make it “not worth it,” is if, e.g., the watch is damaged, and/or the movement components too badly in need of internal cleaning/maintenance to make replacing the capacitor worth the effort.
Great guide … thank you very much. If I was going to add anything, it would be a little warning about opening the main cover. I’ve got fairly strong hands, and I found it pretty difficult to fully separate the cover from the main body, even once I had it started at the corner shown in the guide. The adhesives used by the manufacturer around the edges of this cover are strong, and you have to be patient/careful as you apply the force required to pry all the edges of the cover up and away from the main body, e.g., so you don’t lose control of the Charge, the cover, or your tool as you’re working.
