I restored it as a part of the developer update for iOS9. Prior to iOS9, on iOS8, this happened for each time there was an update released. I don't understand why I would lose data if I can back-up my iPhone and my iPad and have all of the same apps, settings, and data. There is a 'restore from backup' option upon completing the update, but each time I also have set-up the watch preferences again (age, ***, height, weight) etc. for Activity. It wipes all my previous Activity history. I'm not sure why the back-up even exists because if it were truly a back-up, it would have this data and I wouldn't need to set-up the watch preferences again like it was a brand new Apple Wath each time.
