If you got it from Google they would provide return shipping of the defective watch.
The only thing is they actually ask you to go through the motion of purchasing a second watch, so if they do not get the original watch back they would charge you after I think 20 days.
Me I called them,
They emailed me the instructions, UPS label.
I clicked on the link ordered the replacement.
Taped up the original defective watch, used the supplied UPS label.
Dropped the box at UPS drop box location.
They sent out the replacement the same day.
The original defective watch arrived at Google in two days.
Got an email the cost of the replacement watch was completely refunded.
Got the new working watch in 3 days.
Now you being overseas may complicate things.
I know NZ does not use 110volts 60hz, the power could be an issue but I sound like you dealt with this issue before. (Can not see why the Gear adapter would not work) it should supply the same required 5v DC, USB is universal.
