Galaxy watch FOUND

I finally found my watch after 12 months of searching (maybe longer??) … My excitement was short-lived because it won’t turn on/charge/nada! Is the underlying issue the fact that it hasn’t been on or used in so long? Is there a solution? The charge cradle appears to be working (tiny light at the base illuminates when plugged in)… Any suggestions or help is greatly appreciated! Thanks! (Side note: I also found my original Samsung Galaxy watch that I lost before this one, and isn’t responding either…?)

Thanks again!

Cheers,

Blair
