Why not just make the electronics removable through a topside opening to have battery replaced at a watch shop? I don't get why the "jewel" part of this has to be resin molded. Normally you do this because smart rings are made by affixing a flexible PCB with somewhat-bendable battery inside a ring and then molding the entire inner part of the ring using clear resin, but the ring part for this one appears to be just a dead ring.
