What replacement battery did you buy? My 1st gen Moto 360 has been sitting in a drawer in need of a new battery. It would be nice to have working again.
Edit: Just watched the YouTube video and found the kit he used in the comments - https://www.amazon.com/gp/product/B018F1WT8G/ref=oh_aui_search_detailpage?ie=UTF8&psc=1. Is this what you used?
