One would have thought that at some stage, Apple and Garmin would provide watches that allow users to replace batteries by just removing a back cover. Imo, it would be a good selling point. Won't happen of course, both companies are banking on users buying a new watch when the battery fails rather than sending it off for a technician to replace a new one. I have both a Apple Watch 8 and Garmin Fenix 7, when the battery goes I will probably be seduced by new features that I will probably never use. As Tom Cruise once said, "show me the money."
