I've only had my watch for a week, its not the end of the world... but it appears the simple, "unpair/repair" didn't work for me. I am curious why it didn't work, so that is the pain point of the thread. When I got the new watch, I went into the iPhone and selected unpair. That completed. I then selected pair on the new one, and when prompted said to restore from backup and picked the backup from the other watch. The date on the backup wasn't today, so that is potentially part of the problem. I thought the backup was done automatically from watch to iPhone. I got no indication that it wasn't going to work and proceeded with the restore. Upon the restore finishing, I found that it was the default out of the box configuration... no apps... no app data. The new watch wasn't updated to WatchOS2. So, that could have been the issue... and I suspect that it was. I'm doing the update now, and being that it took about 10 hours on the first watch, this kind of spoiled my fun tonight. It does seem to be going a lot quicker this time though. Once the WatchOS2 update is completed, is there any way to get back to the backup from the original watch? It would still save me several hours of fiddling with settings if I could restore from that... but not a huge amount of exercise data that I'd lose since it was only a week.
