Mine did the same thing after using it just over 1 year. I called Samsung and they said I still had a short time left on the warranty, so they got me a return label and I returned the watch and charger. They emailed me saying that it was no longer in warranty, and they wanted a lot of money to refurbish it (almost the same as a new watch would be). I replied that they should just send it back to me. When I received it back, everything worked fine. I don't know if it was the exact same charger or if the sent a new one. It continued to work fine for a couple of months, then stopped charging again. I ordered an aftermarket charger on Ebay; just received it this morning and it will not charge the watch. I know someone else who has a similar watch, I'll try to charge mine from his charger and see if his watch will charge on my chargers. Judging from the other complaints, I'll probably end up getting a different brand of watch!
