My watch is causing electric shock.

To underscore DT8709’s very good suggestion, it’s really important you tell them it’s a safety issue. When you asked for repair, then they care about whether it’s within your warranty period, and will charge you if it isn’t. But a safety issue will have them concerned. This will help you because they will probably not charge you. And if they’re able to replicate the shocks in their own testing, it’s very likely they’ll replace it for free because the watch is defective and they don’t want the risk of anyone using it.

Call into Apple support at 1800myapple and ask to speak to senior advisor regarding a safety issue in getting shocked by the watch. They will probably give you 2 options mail it in or bring it to a store. Apple will evaluate it, and if it is truely a manufacter defect you may get a repair or replacement free of charge. I stress may. The watch is over a year old and does not fall under limited warranty. So it will be up to the repair depot to make that decision. They will send you a email letting you know what their evaluation is and what your options are before paying anything

Take your watch to the nearest Apple store genius bar for an evaluation. You will need to call first and make an appointment.

Mail it.
